Apps/Dead Pedal issue-p0122


Recommended Posts

hey,

i am getting the p0122-(pedal position sensor voltage too low) trouble code with check engine light on my 24 valve cummins. i did the diagnostic procedures listed on this website for that trouble code, on steps 4 and 5 of the listed procedures i got an "O.L" reading on my DVOM which means "open line" i guess? can any one tell me what this means or what i need to do to fix my dead pedal issue (always at beginning of the gear if it happens) ? im pretty new to this cummins and this website. any responses would great! thanks.

                                    

 

STEPS 4 and 5

4. Ensure APPS connector is still disconnected. Disconnect ECM connector. ECM is located on driver's side of engine, just in front of fuel transfer pump and contains a 50-pin connector. Measure resistance       between ground and terminal No. 3 (Light Blue/Black wire) on APPS connector. If resistance is greater than 5 ohms, go to next step. If resistance is 5 ohms or less, repair short to ground in Light Blue/Black wire.

5. Ensure APPS and ECM connectors are still disconnected. Measure resistance between ground and terminal No. 5 (Dark Blue/White wire) on APPS connector. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground in Dark Blue/White wire.
