Guess MY IP is going bad or is bad, I get Dead pedal 20 times daily, but how come sometimes it works and sometimes doesnt??? Why can I simply push in the clutch and let the idle go down and reset and back to power again. If the IP was bad how does it work again for momentary.

thanks

 

Check to see if you have any codes showing.

 

does your check engine light come on?
i wouldn't condemn the IP yet, it might be the APPS going bad
the symptoms are right

 

When my IP went, I also had the dead pedal issues and would regain power if I let off the throttle. I never had the check engine light come on. Upon pulling the codes I found the 0216. If you haven't done so, pull your codes.

 

Yes, pull the codes.... the MIL does not always come on when the 0216 code sets. You only get a light if the vehicle was built to be a CARB compliant vehicle.

From the list of codes in the service manual, the death code is listed as: P0216(M)... with the following note.

(M) Malfunction Indicator Lamp (MIL) illuminated during engine operation if this DTC was recorded
(depending if required by CARB and/or EPA). MIL is displayed as an engine icon on instrument panel.

When my VP44 died, I had the 0216 code stored, but no MIL. When I took the truck to Cummins, their Insight software showed that the ECU logged the 0216 code 58 times.

 

can the typical auto zone pull codes trustfully or should I take it to a cummins shop---both are just as close...also I replaced the apps many months ago to fix a problem with the throttle where some times while I was driving the throttle would go completly out and the check engine light would come on, except for about 1/4 of the first push of the pedal and the engine would rev up real fast but nothing after that. I havnt had that problem since except for dead pedal. I can go down the road and cruise about 60 mph, but the engine will do nothing after that untill I reset it.
Has anybody replaced the IP and still have dead pedal??

 

this is exactly what my 24 v did last week ,no 216 code.It was the apps codes that came up.Try resetting it or get a new one.

 

Oh yes the apps fixed the truck by the way
