Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Good morning and welcome to JustAnswer!!My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.
It sounds like you may have a bad APPS sensor which is the same thing as a TPS sensor but for a Cummins. Is the check engine light on and if yes do you know what codes are setting? Are you going to be doing the repairs yourself or just looking at what could be wrong?
Thanks for the reply!!
No you won't have to relearn anything when you replace the APPS sensor which is called a Bellcrank if you get one from us(Dealership). I would suggest checking the codes first and make sure your dealing with a bad APPS..

The P2127 is P2127-ACCELERATOR PEDAL POSITION SENSOR NO.2 LOW. It's most likely bad and I would suggest replacing it.. In order to test it you will need a scantool to monitor the voltage
Also you will want to make sure the ECM has the latest software..
