About 6 months ago I received the death code P1778 (stepper motor) in my 2008 Altima. I searched far and wide, low and high, only to be told 2 things… you need a new transmission, or you need a new valve body. Since I didn’t have $2500 for a new trans, let alone $800 for the valve body I decided to look into this a little further. watched a YouTube video the only one I could find was a Nissan armada, but thought what the hell. I drained the fluid, dropped the pan, yanked out the valve body, and found that little bastard that gave me such trouble.

Now with part in hand I went to my local parts store, and told we don’t sell that part, its not even in our system… went to the dealership, told the same thing and was told I needed to buy a new transmission as they are not “serviceable” funny but I had the part in hand, how can it be not serviceable?

Lastly I took a gamble, I went to eBay, ordered a stepper motor. 20k miles later, still no code, no whine, and no lock up.

Part Number: 203452A
Description: JF011E RE0F10E F1CJA Transmission CVT Stepper Motor For SENTRAN Nissan Dodge Refurbished
Price: $30-$40

Here is how I saved thousands and bought a $35 part.

  1. Drain fluid.
  2. Drop pan (clean with brake cleaner)
  3. Remove the 3 bolts holding filter. (clean with brake cleaner while your at it)
  4. Remove the valve body about 11 bolts
  5. Remove the stepper motor from the top of the valve body (the side you can’t see with the pan off) 2 bolts
  6. Replace with the new stepper motor found here https://www.ebay.com/itm/282288900117 or https://www.ebay.com/itm/183910578995
  7. Take a piece of dental floss about a foot long and hold the spring loaded arm back against the stepper motor and return the valve body back to the transmission.
  8. After you have a few bolts in place remove the floss before you tighten all the way.
  9. Reconnect trans filter and bolt back into place.
  10. Rejoin the fluid pan to the transmission and replace with quality CVT fluid. Amsoil makes a great product.

I hope this helps and if you have questions please feel free to ask.

About Product & Seller: 

Jemini Power Performance was officially founded on 12/28/17 and named after my beautiful wife who God has blessed me with and who puts up with me dedicating my time to this community. This business and group were created for the 7th and 8th generation, Nissan Maxima. We are specializing in bringing back the well sought after performance y-pipe for the VQ35.

We took the Racingline y-pipe and revamped it to a whole new level. Racingline used bare materials such as mild steel, mild coated with aluminum, and 201 stainless steel to produce the initial y-pipe. We had it tested to see these results. Many people have seen the results of this down the road with rust and premature failure.

What we are now bringing to the Maxima community is far better. Top-quality 304 stainless steel construction throughout that will not rust, all custom made gaskets for 2 entry and 1 exit path, shortened .5 inches to meet OEM specifications and a 2 year warranty.

Everyone knows what these y-pipes do and are capable of. If you have questions please ask. From my own experience, I felt a difference immediately after install. Much smoother powerband from the CVT, no lag at all, and steady pickup. From 0 much more responsive and carries that power to well over 100+.

If you are DIY person and love working on your Nissan Maxima, then this tool is a MUST HAVE! When you go to the Nissan dealer, the person working on your car typically uses a tool called a Nissan Consult. The Nissan Consult that the dealer uses costs thousand of dollars and is only available to dealers. By using the Nissan DataScan software, a laptop and a generic VAG COM OBDII adapter you can achieve just about the same level of on-board diagnosis that $5,000 Nissan Consult provides. This software allows you to:

  • Check CEL codes
  • Check/Reset ABS and SRS-Airbag Faults
  • Check/Reset TCM Codes
  • Adjust timing
  • Perform Idle Air Relearn
  • Reset ECU learned settings
  • Data-log
  • Program keys
  • Check Emissions Readiness Monitors
  • Active Test temporary modify some of the engine parameters for testing purposes
  • And Much much more….

The software itself costs $55.00 and generic cable costs around $7.00-$8.00.

Below are all the functions it provides:

ECU Part Number

This is the main window of the NDSII software which shows the ECM Nissan Identification part number. Basic and Advance Functions can be selected by clicking on the buttons, using the shortcut keys (F1 – F11) or using the Menu bar. Most functions except Data Replay and Log Analyser are disabled until communication with the ECU is successfully established.

Progress bar at the bottom indicates communication between the ECU and PC. If the bar is not moving there is no data being received from the ECU.

Data Display Settings

This window is used to assign parameters to be displayed by the Data Display function. Only parameters that are supported by the currently connected ECU are available for selection. Gauges are counted from left to right, top to bottom. Multiple gauges can monitor the same parameter.

Data Logging ECM

Selected parameters can be logged to a file. This function can also be accessed from the Data Display window. The data log file can be analysed using the Data Replay or Log Analyser functions.

Self Diagnostics ECM

Self Diagnostics function allows users to read and reset engine ECU error codes.

Idle Adjustment

Idle Adjustment function allows users to adjust the base idle RPM. The setting is saved to the ECU and it does not reset with engine restart.

Timing Adjustment

Timing Adjustment function allows users to adjust the base ignition timing. The setting is saved to the ECU and it does not reset with engine restart.

Active Test ECM

Active Test allows users to temporary modify some of the engine parameters for testing purposes. They return to their original values when a function is stopped, PC disconnected or engine restarted.

Note: It is possible to damage the engine if the A/F Base % functions is used to excessively modify fuel delivery. Likewise the engine may overheat if the Engine Temperature is set to low for a long period of time. Do not use those functions if you are not sure how they will effect your engine.

Work Support

Work Support functions allow users to perform some of the advance service procedures. Those procedures may need to be performed after replacement parts are installed.

Clear Self Learn – clears the A/F Base SL map learned by the ECU.

Idle Air Volume Learn – is an operation to learn the fully closed position of the throttle valve.

Program Immobiliser Key – allows to register the Nissan transponder keys with the Immobiliser Note: The immobiliser security PIN CODE needs to be known. Initially all registered keys will be erased and all keys will need to be reregistered.

Cylinder Power Test

Cylinder Power Test function can be used to identify cylinder that is under performing. This function allows shutting down individual cylinders. If all of the cylinders are producing the same amount of power the engine RPMs will drop exactly the same amount on each cylinder that is cancelled.

Log Analyser is used to review log files previously generated by with Data Logging function. Graphs are drawn by selecting boxes next to parameter value. Graph colours match the parameter value colours.

Speed Test

Speed Test is a unique function for measuring car’s acceleration performance. Predefined or user specific tests can be used. Due to the low resolution of Nissan speed sensors, measurements should only be used as a guide and not a true reflection of car’s performance.

Note: This function should not be used while driving on public roads.

Address Watch

Address Watch function is used for monitor specific ECU memory addresses. By monitoring a memory address extra information can be retrieved that is not normally available using Consult II protocol. A knock sensor reading can be obtain using this method if knock sensor memory address is known.

Wideband O2 sensor

Nissan DataScan II also supports wideband Air/Fuel ratio meters from Innovate Motorsports. A second serial port is used to connect to the controller and collect data.

The data from the wideband meter can be displayed or logged in conjunction with other engine parameters using the Data Logging function.

OBDII Fuel System Satus

OBDII Fuel System Status can be used to check if the car’s fuel system is running in Closed Loop mode.

Fuel systems do not normally refer to injector banks. They are intended to represent completely different fuel systems that can independently enter and exit closed loop fuel. Banks of injectors on a V-engine are generally not independent and share the same closed-loop enablement criteria.

OBDII Data Logging

Selected OBDII parameters can be logged to a file. The data log file can then be analysed using the Log Analyser function.

Due to the slow nature of OBDII protocol it’s recommended to log only the required parameters.

Audi R8 Coil Pack Advantages:

  • 50,000 volts compared to Nissans/Infiniti 30,000 volts.
    • Some measure it with Kv so Nissans coils put out 21Kv while VW coils put out 30Kv
  • Quicker Heat dissipation. (Because of its metal body construction it can quickly dissipate heat. Nissan OEM body is made out of rubber that isolates heat instead of disperses it.)
  • More complete burn of the fuel mixture compared to OEM Nissan which equals to better MPG.
  • Idle Stability Improved
  • NO CEL (Check Engine Lights)
  • BEST PART ABOUT THEM IS THEY ARE CHEAPER $$$ than Nissan OEM yet they are much better.
  • Looks 10000% Cooler than OEM Coilpacks

Now the coil packs price varies due to different name brands. They range from $132-$216 for a V6 engine. Below is the link of the coil packs below so you can see the prices and brands. Doesn’t matter which brand you use. They all make the same exact power.

NASHVILLE, Tenn. – A new Maxima 40th Anniversary Edition joins the 2021 Nissan Maxima lineup when it goes on sale this fall. The limited production package builds on the fully equipped Maxima Platinum grade and includes:

  • Unique two-tone Ruby Slate Gray Pearl exterior color with black roof
  • Exclusive 19-inch gloss black aluminum-alloy wheels
  • Black exterior finishers and trim badges, including 40th Anniversary badge
  • Black exhaust finishers
  • Red semi-aniline leather-appointed seating with 40th Anniversary embossing
  • Red contrast interior stitching
  • Satin Dark Chrome interior faceted finishers
  • White speedometer and tachometer faces reminiscent of past Maxima models
  • Heated rear seats

Maxima is the longest continuous running Nissan nameplate in the U.S., linking back to 1981, the year Maxima was first sold here.

As the flagship of Nissan’s vibrant sedan lineup, which includes the trio of recently redesigned Altima, Sentra and Versa models, Maxima continues to garner prestigious industry awards. In June, Maxima was named the top vehicle in the Large Car segment of J.D. Power Initial Quality Study for the third consecutive year. In July, Maxima led J.D. Power’s APEAL Study Large Car category, again for the third year in a row and 30 points ahead of the segment average. It has also achieved a Top Safety Pick rating from the Insurance Institute for Highway Safety for five straight years1.

In addition to the 40th Anniversary Edition, the 2021 Maxima will be offered in SV, SR and Platinum grade levels – each equipped with a 300-horsepower 3.5-liter DOHC 24-valve V6 engine and Xtronic transmission.

The Original “4-Door Sports Car”
Today, Maxima is known for its premium level of luxury with performance and sportiness. For generations, before the arrival of diamond quilted Ascot leather-appointed seats, Satin Birdseye Maple wood finishers and 11-speaker Bose® Premium Audio system, it was simply known as the “4-Door Sports Car.”

Now in its eighth-generation, Maxima’s storied history as an authentic sports sedan goes back even farther to the Datsun Bluebird 810 of the late 1970s. The 1981 Datsun 810 – often described as a larger interpretation of the legendary Datsun 510 – was the first to carry the Maxima nameplate.

Dropping the 810 name, the true first generation Maxima featured the engine of the 240Z and a 5-speed manual transmission at a time when industry standard was a 4-speed box or less. Next came the second-generation 1985 – 1988 Maxima, which was the first to offer a V6 engine and front-wheel drive. It was the last to be available with a station wagon body.

The third-generation Maxima emerged in 1989 as the true 4DSC. Considered the best affordable sedan in the world by many, it was powered by a 160-horsepower 3.0-liter V6 and went head-to-head against European sports sedans in road test comparisons by leading automotive publications.

Not willing to rest on its laurels, the Nissan engineering team came back in 1995 with a larger body design and featuring a new engine, new rear suspension and 30 extra horsepower (190-hp). It was chosen as Motor Trend’s Import Car of the Year and was included on Car and Driver’s 10 Best list.

Three more generations followed quickly. The fifth-generation Maxima, introduced in 2000, received the legendary VQ35 V6 and a boost to 255-horsepower (from model year 2002). In 2004, the sixth-generation Maxima upped the luxury factor substantially. The seventh-generation added new aggressive styling to go along with the now-290-horsepower 3.5-liter V6.

In 2016, the current-generation Maxima debuted sporting the V-Motion front end and floating roof design. A minor facelift followed in 2019 with enhancements to its safety, security and connectivity technology.

Over four decades, Maxima has remained faithful to its heritage as a true performance sedan and brand flagship – as well as to its large owner base, which is among the most loyal among all Nissan models. With the addition of the special 40th Anniversary Edition, Maxima adds to its long history once again.

More information on the full 2021 Maxima lineup, including pricing and specifications, will be announced closer to its fall 2020 on-sale date.

Introducing The Nissan Maxima 7GM/8GM Shockwave Tuned Helmholtz Exhaust System. This exhaust works on both 7thgens (2009-2015) and 8thgens (2016 to Present).

Full Exhaust Price: $1,429.00
ART Y-Pipe Price: $592.00

Order Link: https://motordyneengineering.com/product-category/nissan-maxima/nissan-maxima-exhaust/

A high quality build, completely polished, TIG welded Stainless Steel 304 tubing with a 2.5″ inlet and dual 3″ outlets utilizing carefully tuned Helmholtz resonators for precise sound control. This high performance system provides a bright and deep warble with high detail in the exhaust note. At idle and cruising speed the sound level is clean and moderate but when you step on it and bring it up to high RPM it really earns its name the Shockwave.

The uniquely shaped midpipe muffler allows for gradual wave expansion into the sound dampening fiberglass for greatly reduced drone and rasp. The midpipe muffler uses 3 stages of high, mid and low frequency sound attenuation. The first stage of the is 3.5″ diameter and it works like a small glass packed resonator. A small resonator is effective at reducing the high frequency content of rasp while a large muffler is better at lower frequencies. The 3.5″ section then expands to a 5″ diameter glass packed resonator where the sound then expands to a thicker layer of fiberglass for midrange sound attenuation. The back end of the midpipe muffler is leads into an axially aligned protruding annular orifice that gives the equivalent of a 8″ diameter. The total sound reduction is performed in three stages of high, mid and low frequencies for broad band sound reduction. Smooth deep sound with pure straight through flow. The flow is then divided into a dual 3″ axle-back section that uses 2 large Helmholtz side-branch resonators for sound control. Combined with the ART y-pipe the result is straight through flow with deep sound, no drone and no rasp.

If you are reading this article, you are very likely trying to resolve P0420/P0430 without having to spend a lot of money on the issue. Most of the time, the codes are due to a bad clogged catalytic converter or bad O2 sensors. Before replacing the O2 sensor, be sure to do the spacer fix modification first because O2 sensors are not cheap.

There aren’t usually any drivability issues associated with these codes. For most people, the first sign that anything is wrong at all is the check engine light. Below are the typical check engine lights you would normally get:

  • P0420 NISSAN – Catalyst System Efficiency Below Threshold Bank 1
  • P0430 NISSAN – Catalyst System Efficiency Below Threshold Bank 2

The Fix

You can eliminate the codes by using a spark plug non-fouler which tricks your engine computer to think that everything is working fine. This simple trick will pull the O2 sensor away from the exhaust flow and the computer will think the Catalytic converter is working properly. This will work if you remove the catalytic converter or have a bad cat. It’s very simple and cheap to do. Below is a video on how to perform the fix:

You can also buy them pre-made on eBay if you do not want to drill.

 

Make Your Own Spacers/Foulers

You can buy these non-fouler spacers at your local parts store. You can get them from Advanced Auto or Autozone for about $7-8 bucks.

You now need to drill out 1 of the non-foulers using a 1/2″ drill bit. When finished this is what it will look like.

Second, unmodified non-fouler now installed on modified non-fouler, then threaded into the pipe

Below are photos of the spacers installed and 100% working on Nissan Maximas by generation. After installing the spacers, the CEL codes went away.
