Hello everyone. I am new to this site and looking for a little advise:


I have a 2002 S40 1.9T Automatic with 158,000 miles. It runs like a champ, but recently it has displayed the Check Engine Light. Reading the code shows P0722 (Throttle Position Sensor). I have cleared the code two or three times, but it comes back after a number of journeys. Transmission shifting appears to be normal.


This leads me to a couple of questions:


1. Has anyone had this fault code and, if so, what was the cure?
2. My trusty Haynes manual shows two transmission control sensors: vehicle speed and transmission speed. Is P0722 caused by one of these? If so, which one?


Thanks in advance for any help!


Pete.

 

could be a ground wire issue on the transmission or the transmission (output shaft) speed sensor - Google Volvo PN#30618272 Its about $100 so no too bad...

 

Thanks for the feedback. I will certainly take a closer look at the transmission electrical system. Is there a way to check the sensor (e.g. continuity) or does it fail in different ways so the only sure method is replacement?
