for 2k2 2k3 owners, if you need a new MAF...
Hey, hopefully this will help someone out. I noticed a loss in power and decided to swap out my MAF. I already did the 2k1 MAF + thermistor swap two years ago but was never really happy with the results.
I looked on Rockauto and Amazon and noticed that Hitachi sells just the sensor for $109 (for the 2k2) and bought it. For the last three weeks, my car has never run better. It may be a good alternative for those who don't want to modify the 2k1 MAFs. Hitachi is the OEM supplier for Nissan coils so I figured they would make a decent MAF and I like the outcome.
Here is the 2k2 MAF I bought from amazon.

Hitachi catalog shows a different part number for 2002 and 2003 maximas

I installed this MAF on Saturday to see if I could improve my gas mileage issue, but that info will be granted in due time I guess.... but on another note, I can tell my idle has gotten smoother, and acceleration has improved also so I am pleased with the purchase 
So i had purchased the $22 Maf posted in this thread as well....
that may be my issue i think still. Still experiencing rough idle/power surge/lack of power issues. Guess will be buying the hitachi one next.

Code P1122 is the Electric Throttle Control Actuator assembly. It consists of the throttle control motor, throttle position sensor. The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The opening angle of the throttle valve is detected by the throttle position sensor and it provides the feedback to the ECM to control the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
You either have a bad Electric Throttle Control Actuator or the wires going to it are damaged.

Check 15 amp fuse # 63 that is under the hood by the battery. It is towards the front of the car and the cover has the label THROT MTR on it.
There is a relay in the circuit. It is in front of the battery, the row next to the battery, 3rd one from the left. Relays don't go bad that often, but it is a possibility.

I just found the original MAF Sensor from my old 2003 Maxima SE 6MT, sitting in a box of parts from way back when. It has approximately 50K miles on it, from 2003 through 2010. There are zero problems with the unit... at the time my thinking was to experiment with the 2001 MAF + Honeywell Thermistor, and have the original as a back-up, since the MAF is a known point of failure on the 2002-2003 Maxima. (That approach works just fine, BTW. Although my soldering skills suck *****.)
New, the price is stupidly high. We all know that, and are familiar with the sticker shock when you need one. Now that there are aftermarket MAFS (because there didn't used to be), it seems to go for $110+. After discovering that I still had this part, I thought about creating a FS thread, but then found this active thread when researching what to do with it.
Most of you here probably don't remember me, but NmexMAX can vouch for Rochester, right Manny?

Wow.
Larger MAF housing using the same OEM MAF is a good idea, but not that straightforward.
And yes Rochester, there are a few MAF's now even the 02+ that are relatively inexpensive not 400$, and of course there's the 00/01 option wnad swapping the thermistor, and of course the community has matured more so as of late that now even the thermistor is available for separate purchase.

Hope all is well, Manny.
Great price.

No, no performance gain.
