I have a 2002 S60 that has been idling badly, and the check engine light just came on yesterday with error code P0068 "MAF/MAP Sensor Throttle Position Correlation".

After some research here and elsewhere I think it is due to the ETM and/or Throttle Body. I cleaned the throttle with some cleaner which made no difference. I also found out the car had the ETM unit replaced on recall about 6 years ago and according to Volvo they only do that once.

Do I need to replace the ETM or can it be cleaned somehow? Any other suggestions on what to try to easily resolve this? I don't have a lot of cash and this car is driving me crazy with all the things that have gone wrong with it once it passed 100K miles :-(

Thanks,

Mark.

 

either you got a misfire and you need to replace your plugs or your throttle position sensor like it says
