I had a P0221 code thrown the other day. And it seems to be Throttle/Pedal Position Sensor/Switch "B" Circuit Range/Performance. For those who have dealt with this issue. what needs to be done? and where is the TPS? Incase i have to replace it.
TPS is on the gas pedal. A search on here should provide quite a few posts on the subject including how a SD one can work which is cheaper then a whole new OBS assembly. Also some good information from Old Man Dave is on here about the Dorman sensors and issues.
