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.

 

make sure your batt is good and all connections clean, my last 122 code was fixed that way.post the info on your truck guys know what your working on
