OK.. I know I am new here, but here goes. Took my 2000 maxima in 2 days ago, the MIL was on. They claimed they couldnt find anything currently wrong, but it gave them 2 codes, both Fuel System Lean codes (0171 & 0174). I took it home, light came back on last night. I took it in today, and they are claiming the MAF sensor needs replaced now (681.77). This seems a little strange, any advice?

 

search the site - the MAF failure is pretty common. I think there was a TSB for it.

Search the site - apparently the actual sensor can be purchased for as little as $70 dollars and it is a very simple repair.

The people on here are excellent - they have done almost everything you can do to a car and have experienced and solved almost every known problem with the 5th gen Maxima.

good luck

 

Clean the MAF. Or, replace it if need be.

 

Check with emax95, he has figured out a way to clean them.

 

You can clean a MAF and not have to replace it? Oh joy if this is true....
