What is the correct OEM MAF sensor?

Post by butlerjonas »

2009 Vibe GT, 2az fe engine. I've bought two Denso MAF sensors and they both crapped out in a matter of months. Cleaning them did no good, but replacing them worked for a while. The one in my car when I bought it was a Denso, but I've heard I should get an AC Delco or Delphi. I'm not made of MAF sensors, ya know! Please advise.

Pretty sure Denso is the OEM MAF, given that this is a Toyota.

Cleaning MAFs is pointless for the 2 microscopic specs of dust they may accumulate.

If you are buying MAFs from eBay/Amazon, odds are you're not buying real ones.

What says the MAF has died repeatedly? What is the CEL you are getting?

Bought the MAF from Advance Auto. Denso #197-6110. Code is P0101. No other codes and obd shows airflow and fuel trims going haywire, like 25 grams per second at 1500 rpm, and negative 20+ LTFT. I also read reviews that this MAF didn't last long for other people either.
I think you're right, though. Most "AC Delco" parts for this car are really Denso or Toyota.
I also don't think I was clear before. I've only bought this one MAF that failed in 5 months. The original one failed after 12 years.

*update*
I Cleaned the MAF with CRC cleaner. I Didn't think it would help, but the wire that faces the airflow was a tad darker/duller than the others.
Anyway, now at idle:
STFT: -0.8
LTFT: 0.0
Success!
