You are probably wondering, what is the difference? The difference is that the #50-1220 (new version) fits our OEM fuel pump housing 100% PERFECT. This fuel pump is the most fuel flowing pump on the market that can support over 1,000hp and does not sacrifice you getting rid of your OEM fuel pump housing, which also means it does not need an install kit as most do. That is the beauty of AEM’s updated 320 LPH Fuel Pump. It’s also compatible with E85.
I confirmed with AEM that they changed the design of that portion of these pumps to the more common type of plug connection. The rest of the dimensions and specs remain the same. Kit still comes with the pre-filter sock, sock clip, submersible hose, two hose clamps, harness plug, lower rubber pad, some rubber isolation options, instructions, and an AEM decal. Most part distributor sites are not using updated photos. Even AEM’s own website isn’t updated to reflect those changed.
Fuel pump size comparison. #50-1220 on the left, and #50-1200 on the right.
OEM Fuel Pump Connector Reference – You can see why the #50-1220 is plug-n-play.
This will allow you to use a newer Mass Airflow Sensor to your 2002-2003 Nissan Maxima. This upgrade has been available for many years in the Maxima community. The newer MAF sensor is pretty much the same as 90% of the newer Nissan Models. Much cheaper and easier to find. You just need to be sure you also use the newer MAF housing when installing.
You can either get an OEM pigtail or use the one from eBay below. I went with the eBay pigtail which costs around $16 bucks shipped. The most important part is that you follow the pin order (wire colors do not really matter as long you follow pin order).
********************************* Important Note: In order to properly use this new MAF, your car will require tuning. The car will drive OK but your idle will be off and may fluctuate. If you’re preparing to get an ECU tune using stock ECU, make sure to let your tuner know so new MAF can be factored in. *********************************
For installing, you just need to match the wires as noted below. Very simple but please proceed with caution.
2002-2003 5thgen Maxima MAF Pinout
Pin 1: MAF Signal (White) Pin 2: 5v (Red-DO NOT USE) x Pin 3: Ground (Black) Pin 4: +12v ( Red/Green) Pin 5: IAT Signal (Yellow/Black)
For reference, once you swap to this MAF… you can use MAF’s from any of the cars below. They all share the same exact MAF which makes this a better option.

UpRev is still working on this ECU. Once it becomes available, the 8thgen 6-Speed Swap will become a reality as the proper tuning will be available (like the 7thgen Nissan Maxima).
The fans on my 6thgen Maxima went bad, so I decided to try out these eBay ones before buying a more expensive brand again. At this price, I figured I could repurpose them for something else in the event my car was not cooling properly. I previously had a SPAL fan where the motor seized. To my surprise, these actually ended up working great with no issues. While a shroud is recommended, I don’t have one and my car didn’t have any issues with cooling during the summer. I have an external water temp gauge and temps are as they normally should be.
So if you’re looking for a Mishimoto alternative or OEM stock fan replacement, you can give these a try. And quite honestly, I saw no difference between these and a set a Mishimoto fans that I have on another car. I have these wired up directly to stock harness used a 4thgen Maxima pigtail. No external relay was required for these.

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.
Drain fluid.
Drop pan (clean with brake cleaner)
Remove the 3 bolts holding filter. (clean with brake cleaner while your at it)
Remove the valve body about 11 bolts
Remove the stepper motor from the top of the valve body (the side you can’t see with the pan off) 2 bolts
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.
After you have a few bolts in place remove the floss before you tighten all the way.
Reconnect trans filter and bolt back into place.
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.

While this is advertised as Plug-n-Play, it’s really not. You have to run some extra shielded wires for two signals as it does not come with with the crank and cam signal wires. This has happened to about 4 maxima owners who purchased this harness. Overall, the harness does work but it’s not straight plug-n-play and questionable if its worth $500. Car may or may not run without these wires so please keep this in mind.
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.
You can find the cables on eBay between $12.00-$20.00 shipped. It ranges based on location and shipping. Search for the following keywords on eBay and you will find it: “KKL 409.1 VAG-COM OBD2 USB Cable”
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.
ECU Part Number BCM
The BCM tab shows the BCM Nissan Identification part number. Basic Functions can be selected by clicking on the buttons or using the Menu bar. All functions are disabled until communication with the ECU is successfully established.
Progress bar at the bottom indicates data being send between the ECU and PC. If the bar is not moving there is no data being received from the ECU.
Note: Some vehicles may use K line for diagnostics of engine ECU (ECM) but still use DDL1 line for diagnostics of other control modules. This software does not support diagnostics over the DDL1 line. Some of those models are: X-trail, Maxima, Patrol.
Self Diagnostics BCM
Self Diagnostics function allows users to read and reset BCM error codes.
Active Test BCM
Active Test allows users to temporally activate some of the functions of the BCM. This is usually used to manually test the functionality of the systems controlled by the BCM.
Note: Functions not supported by the BCM are disabled (grayed out).
ECU Part Number TCM
The TCM tab shows the TCM Nissan Identification part number. Basic Functions can be selected by clicking on the buttons 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 data being send between the ECU and PC. If the bar is not moving there is no data being received from the ECU.
Note: Some vehicles may use K line for diagnostics of engine ECU (ECM) but still use DDL1 line for diagnostics of other control modules. This software does not support diagnostics over the DDL1 line. Some of those models are: X-trail, Maxima, Patrol.
Data Logging TCM
Selected parameters can be logged to a file. This function can also be accessed from the Data Display window so the data can be logged while it is displayed. The data log file can be analysed using the Data Replay or Data Analyser functions.
Self Diagnostics TCM
Self Diagnostics function allows users to read and reset TCM error codes.
ECU Part Number ABS
The ABS tab shows the ABS Nissan Identification part number. Basic Functions can be selected by clicking on the buttons 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 data being send between the ECU and PC. If the bar is not moving there is no data being received from the ECU.

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.
OBDII Self Diagnostics
OBDII Self Diagnostics function allows users to read and reset ECU error codes.
OBDII Monitor Status
OBDII Monitor Status shows the current status of various monitoring systems used by the car’s engine management system.
OBDII Log Analyser
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.
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.
