Nissan Technical Advisor 11/28/2010What is the code? My suspicion is either the knock sensor or the CPS is failing. Have it verified by a scan tool and replace parts if necessary.
HouseCallAuto 11/28/2010I doubt the TPS is bad. besides, if you unplug the TPS, the computer will substitute a fixed value in place of the open circuit that it reads and the car would still run. You need to read what fault codes are there or you cannot fix the car.
Mike 11/28/2010I'll check the codes in the morning. Thank-you
