Post subject:  Throttle is stuck WIDE OPEN
On three occasions during hard acceleration, my throttle stuck wide open. From my old junker driving days I started tromping and releasing the foot feed, after several attempts it freed up. My first thought was that the floor mat had somehow keeping the accelerator depressed. Any suggestions for resolving my problem? Any help will be greatly appreciated.

Throttle control valve needs cleaning? :?:

Since the throttle is electronic I would think the pedal is getting stuck, or the potentiometer is sticking.

When it happened to me, it was my floor mat.
I moved the floor mat and the problem went away.
The system is drive by wire, no mechanical control.
So don't try spraying Gumout Throttle Body Cleaner into your intake, it will act like fuel and the engine will either run away or run like crap.
Any Suckers who want to be testers on that one?

The RHD 2002 CRD that I have does have some mechanical control ie. there is a cable going from the throttle pedal on the RHS....snakes over the first turbo hose...under the plastic engine cover and then into the TPS potentiometer on the LHS near the battery.
It is quite a tight routing of the cable and the cable sheaf easily pops out of the TPS sensor housing which can cause binding...I cut a small section of plastic off the lower part of the engine cover to give the cable a straighter line of travel and that helped. :)
I dont know how the LHD system works. :?

Different machine than what we have stateside. Like Warp said, ours is drive by wire. When mine stuck, it was the floor mat. It happened one too many times and I did normal maintenance and replaced the mat (it was worn out anyway). Now, for now, no sticking during WOT.

Yup, 2002-2004 CRDs use a mechanical pedal, attached to the APPS in the engine bay.

All in all sort of a weird setup considering the XJ 2.5 diesels had the APPS in one unit on the floor.

Really all quite odd.

Sir Sam, can you tell me what APPS stands for?

**Erh I figured it out, lol long day

accelerator pedal position sensor*** Added

Thanks :D
