2001 3500 5.9L - P0122 and P0223 codes -- replaced TPS/APPS with no change - starts and idles great but dead pedal -- thoughts??

 

What sensor did you use? Set idle voltage? Recalibrate after installation? Hopefully you didnt get scammed at the dealer. I always recommend Timbo

 

Thank you -- had my baby since new (2001) 53,000 miles with huge 2001 (4000 lb) Bigfoot in bed (had offers to buy but I am 81 and it will die with me). Haven't driven her in a year -- starts great and runs great -- took it out on road and went 1/4 mile and dead pedal. Brought it back home in idle using low on transfer case and low on transmission -- sweet. Codes P0122 and P0233 (low and high voltage codes??) Replaced the TPS (APPS) with Amazon unit and nothing changed. Starts and idles great, goes to high speed with sensor unplugged. Read 5 V on sensor input and sensor acts like potentiometer under resistance testing. Did not do any intrusive testing (pin) or wire trace to ECU. Have now ordered a Timbo (thank you and many others in the past.) Will keep you posted after it arrives and I install and calibrate. Regards from the North.
