theres a lot od problems with aftermarket mafs on r50 pathys. an 01 maxima maf can be used instead and is much cheaper than a new oem pathy one

Yeah.  It was a purchase made while trying to sort it out quickly.  I’m surprised that it had the same problem as the original though.  I am likely going to sell the R50 and it doesn’t make sense to spend a lot of money.

P1102 is a maf code. You said you replaced the maf...did you use an oem replacement....or aftermarket? 

Aftermarket

My intake temp sensor shows all sorts of false readings. I get 300degF spikes often with no real noticeable effect. I’ve replaced my IAT sensor already though and checked the wiring extensively and the problem persists. I think I submerged my ECU in muddy water and that’s what my issue is..

Anyway, I just wonder how much effect the IAT actually has on the ECUs tuning. Can you just unplug it and see how it runs?

No IAT.  It’s gone.  I guess it has been.  Apparently something else is problem.  Runs fine cold, then it won’t idle after it gets a little warm.

Ducting before airbox is gone.  Had been running fine in spite of that.  

[02 R50 Dilemma]

Maybe it’s running like @!*% for a different reason. 

[02 R50 Dilemma]

Oh.  That explains it.  The DTC is P0113 though.  

[02 R50 Dilemma]

I guess I thought the intake temp sensor was integrated in MAF sensor.  Hope they’ll allow returns.  

 

Is the intake temp sensor on rear of the throttle body?

[02 R50 Dilemma]

Thanks.  I’ll check it.

I have a 2002 R50 automatic with 150,000 miles that was damaged in the front end but running well, though driven sporadically.  Now it’s throwing a high intake temp sensor code all of the sudden.  New MAF didn’t fix it.  Won’t idle on its own.  Thoughts?
