Can someone please confirm which maf sensor is oem for 2005 s type 3.0 na. I've got a Denso sensor in there 197400-3021? or 43-12B579-AB? Not sure which is part #. I have tried aftermarket sensor in the past and it worked for a while but leans coming back and I've eliminated everything else. I want to just buy a factory oem sensor and give it a go.

 

What codes does the car have?
Why do you think the MAF is the problem?
Proper troubleshooting is always more effective than loading the parts cannon.

Sir....I'm the original owner of the car. I've maintained it myself for the most part for it's entire life. The lean codes on this car have come and gone for YEARS. I have done ALL the other causes...IMTs, fuel injectors, fuel pump, vacuum lines, coils, plugs air filter, throttle body, fuel pump o ring and on and on and on....I had it cleared for a couple years after doing all those things, including replacing the maf with an aftermarket Duralast maf. I kept the one that was in there which was a Denso. When the leans and cel recently returned, I for the hell of it, swapped out the Duralast maf with the Denso that I had kept and the codes INSTANTLY cleared. So, the old original Denso is still in there, and I was merely asking of others......is the Denso MAF the preferred MAF by others for that car before I go buy another Denso. I'm actually tempted to try a $40 Amazon aftermarket just so see if $40 makes it better.

 

Hello,
the Denso sensor for your 3l engine has the number: DMA-0113.
