01 Ram Ext cab 4x4 Cummins driving down the road and all the sudden it is stuck reving high and just driving along at the speed I was going never slowing down, unless I went up hill. I have to shift into N just so I can use the brake or it's like stopping a runaway train. Pulled over and shut it off thinking cruise may have electrically engauged and still ran the same. I just had a APP sensor which I purchased from Geno's Garage installed by the Dodge dealer tech, on the side, in town. I assume that could be stuck as well but how do I fix it? Or do I just need to get another sensor? Thanks

Sensor was installed on May 6th, so it didn't even make it a week. That is if that's what's wrong

 

did you check to see if the cable was hung up or the lever under the cover on the apps is stuck

 

No but I checked for codes by turning the key three times and I get the P1693, which is a companion code, from what I've read.

 

P1693 is just a companion code.

Means either the ECM or PCM has a code in it.

 

does it run that way on cold start up?

 

well i would check to see if there are any obstructions holding the apps open. and the 1693 is a code picked up from the jtech module (pcm) and cannot exsist by its self. there has to be another code in it also its just not giving it to you. if there is nothing holding it open its an electrical problem and its time to start chasing it.

 

you could also try to reset it....i beleive the proseger is turn key on mash throttle to the floor then let up slowly till all the way off and shut key off....then start and and see what happens...may not work but its worth a try as long as the throttle is working correct

 

APPS Reset Procedure
This procedure has shown to help 24 valve ISB engines. It is basically teaching the fly by wire accelerator on these trucks to reread the position of the pedal and it's limits. Most complaints this will help with is poor acceleration, improper shifting, bucking in 5 and 6 speeds. Has been known to increase fuel mileage in some instances.

1. Set parking brake
2. Disconnect negative battery cables on both batteries
3. Turn ignition key to run(to drain any remaining capacitors)
4. Let truck sit for 30 minutes( this is the recommended minimum)
5. Return ignition to OFF position
6. Reconnect both batteries and secure, not a timed event
7. Turn key to run position(not start) and depress accelerator pedal slowly all the way to the floor
8. Allow pedal to return to top position slowly
9. Turn ignition switch OFF
10.Release parking brake

Here is the steps for the apps reset. It would be worth a shot i think

 

i thought so to just couldn't remember the steps.....nice post BTW

 

No problem
