Hey all, I have a 2001 24v and a few months ago i started noticing the throttle acting weird / revving up and letting off on its own a tiny bit when cruising around 55mph, I would then put it on cruise control and wouldn't notice it. Then the other day I noticed after driving on the highway/ with cruise control I'd get off to get fuel and the truck would be idling high around 1k until I shut it off and re start then it would be fine. Finally on the trip home I was running 70mph with cruise control on and the cruise control cut off and the throttle went unresponsive and threw a check engine light. I did the key thing to get the codes on the dash and got p0500,p1693,p0121,p0523,p0602. I'm running a Smarty and from my uneducated google knowledge I'm assuming I have a bad apps and if I replace it I should be good to go. My question for all of you is, is my assumption of having a bad apps correct, is there anything else I should look into from those codes. Also if I do need a apps where should I buy it. My brother inlaw is a self employed mechanic and seems to get parts cheaper if thats a consideration, i'm pretty sure thats just threw people he has accounts with though such as orileys, napa places like that. All your help and knowledge would be appreciated. Thank you. -
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.
