MAF now....

[AJRK]

So, after replacing a second O2 sensor yesterday, the SES light came back on today... So back to the shop I went... they told me it was the MAF and it was reading 135 when it should be about 100. The technician cleaned it then took the car for a drive and he told me he got the reading down to about 120.

Can anyone clarify this a bit for me? My understanding is that MAF controlls the fuel mixture and if the high readings persist, I'll have to replace it.

Thanks!

I can't say for sure that is your problem.

However, check this thread:

It seems to me that MAFs fail frequently on 2001 Pathfinders and QX4s. That might be just an observation.

Did your SES code come up as a lean bank? That's what mine had.
