Now that I think I may have fixed my badly shifting tranny with a full ATF flush, onto the next problem.

I have had this error code for a few weeks now, car runs ok, just idles high sometimes and has stalled on a few occasions after driving at highway speeds then stopping at an off ramp.

I cleaned my throttle body and MAF sensor, don't think it helped much.

The way I understand this error code is a disconnect between the MAP or MAF and the throttle positioning sensor, so it could be either part.

Is there a definitive way to check which sensor needs replacing, the MAP, MAF or TPS?

Thanks,

Mark.

 

MAF is easy, unplug it and run the car. if it runs better than its likely bad.

there are youtube videos on the other two sensors
you need a multi meter tho

 

Took a look around the engine to take out the TPS to test it, but not sure my S60 even has one? I don't see anything that looks like a TPS and notice none of the online parts sites sell a TPS for a 2002 S60, does that mean it is just built into the ECM?

Thanks.

 

the TPS is part of the ETCM (electronic throttle control module) if you take out the throttle you will see a black plastic cover its under there, so in short its not a replaceable part you have to replace the whole electronic throttle. however i belive there is a recall on some of those so it "might" be free for you

 

Thanks.

I found out that the ETCM was replaced already under recall a few years back (before I had the car).
