2007 Dodge Ram 1500 5.7L - In limp mode - Codes: P2123, P0222, P0122 - APPS1 has NO VOLTAGE even when the pedal is to the floor - APPS2 has voltage and changes as pedal is pressed - Thinking pedal sensor assembly is bad but wanted a second opinion - Thx

Sorry for the delay...

The 122 and 222 codes are for the electronic throttle body. So I would change that first then see how it does. The 2123 is for the pedal assembly but may be false. However You may have to replace both the pedal and the throttle to get it right.

Can you explain why there is no reading from the accelerator pedal position sensor 1? It is showing no voltage at all on the data stream, even when the pedal is pressed to the floor. APPS2 is working.

Sorry for the delay...

If you have no reading from APPS1 then the pedal sensor has failed also.
