I have a 2012 Quest SL, 110k miles, and the malfunction indicator lamp (MIL) has been on for about 1000 miles with no change in performance. Autozone told me the code corresponds to the mass air flow sensor (I do not have the code: I intend to verify). So I pulled the MAF sensor out and cleaned it with CRC MAF cleaner. The MIL did not disappear immediately, but it did after maybe 2-3 days. A week later, it is back again and my local mechanic said I need to take it to a dealer for the PCM to be "flashed" (reprogrammed) and the dealer says that it would be no good to do that without installing a factory MAF sensor first -- all in that's around $500 to the dealer ($270 sensor + $70 labor + $130 reprogram ...). Has anyone experienced this issue? Can anyone confirm that if I just install a new (aftermarket, $30-60) MAF that I really have to take it to the dealer for PCM reprogramming to clear the code? It literally takes 10 minutes to change.
