Installing New MAP Sensor

[Vapor]

I have a 2001 Maxima SE. SEL came on so I had it checked with my local repair shop. Told me P0171 code was present. He checked the MAP sensor and said it was at the end of it's life. Took the car home and purchased a new MAP from (thepartsbin.com). I have not installed yet because I need some feedback from members here. The following warning came with the unit.

1. This airflow meter assembly must be replaced as a complete unit. Do not remove the element and transfer to the old body.

2. This unit requires special ECM reprogramming of the vehicle.

3. Refer to TSB NTB01-036/ITB01-029 for the special ECM ID code that must be entered in the ASIST ECM data screen to download the correct data.

4. This data is not available through the regular MY / Model lookup.

5. Replace the air filter and clean all dust/dirt from the air cleaner box.

Steps 1 and 5 are no problem.Steps 2,3 & 4 are above my ability. Do not have the equipment. Are these steps absolutely required to complete the job?

As far as I know, replace it go to autozone, have them clear the code and you should be good to go. I very well could be wrong, wait, and maxhopper will be able to answer this for sure.

I know you said you got a MAP sensor. But those directions sound like you got a MAF (mass air flow)?

Sorry about the typo. Yes, you are right, I am talking about Mass air flow sensor.

I found where the TSB recommends an ECU reflash, but I don't know if it's because the sensor has been updated. In doing some searching, I've read where some people have not gotten the reflash, and not had any problems.

I would say go with Noah's suggestion about replacement and clearing the code. But if you have any further problems, I would have the dealer do the reflash. The dealer should only charge a maximum of one hour labor to do the reflash.
