Help with Throttle/Pedal Position Sensor
Hi Guys,
I had to replace the intake heater relay on my 01 2500 Diesel (24 valve) the other day, and when we cleared the code, another pulled up. This time it's the Throttle/Pedal Position Sensor/Switch B Circuit Low Input. The code reads out,PO222 but I found that it is really PO2122. Reading the threads on this subject, I see it's an APPS rather than aTPPS.
How do I determine if it is the sensor, or the connection?
Could I have fouled the connection while I was rooting around with the intake relay?
BTW, the truck seems to be running just fine, but the engine light is still on.
Any information you all can give will be appreciated.
Thanks
Have fun
Rufus

On an 01 with 115K you are probably due for a new APPS. I put a timbo on mine back then and its a non issue.
I didn't have a code, just an odd miss at any steady speed....
