Help ! Accelerator pedal not working

[garythompson]

On Returning to My 2000 Boxster S after work the other day The Accelerator pedal Had no effect The engine simply Ticks over however much the accelerator is pressed.

Called out the rac and he seemed to think it was the engine actuator end of the throttle system But I dont have much faith in his diagnosis seeing as i had to show him how to get to the engine!

I have looked at a few old posts regarding Accelerator problems but most of these seem to be slightly different faults . I dont really want to go through the expence of having a repair carried out by the OPC Is there any kind of throttle reset i am able to carry out without special equipment or way of finding out which part is faulty so that i am able to replace it myself.

Where are you located?

There are some tests you can run with a PST2 (or PIWIS) that should help narrow it down.

Loren is correct that the PST2 should show if it is the throttle potentiometer at the pedal end, or the actuator at the throttle body which is the problem. Unfortunately, I'm quite a long way from you otherwise I would have been happy to help. If you need an independent specialist, you could try Parr at Crawley, West Sussex. I've also heard very good things about Addspeed Engineering at Horsham - probably cheaper than Parr too.

I have taken off the throttle body (Engine end) given it a good clean , and the car is now revving to about 2000 rpm wit full pedal deflection . I thought that this sounds like this is the faulty item ,BUT i have just noticed that when the cruise control is switched on the cruise light does not come on on the dash. this is controled by the motronic unit in the trunk (boot). so maybe i am looking at a far more detailed and expensive fix than first antisipated.

Problem solved thanks to the guys at Addspeed in Horsham. They plugged in their PST2 and diagnosed that the throottle body was at fault got one from porsheapart for£150 (590+VAT from dealer) and had it fitted and error codes erased all good now .
