C3 1.4 HDi Fault Code P2137

A friend has had the engine management light illuminate of her 2004 C3 1.4 HDi, I gave it a Lexia session and found three codes, the first two; P1357 Pre heater relay circuit plugs not supplied and P0215 Ignition system supply relay circuit stuck were shown as intermittent and stayed cleared for the duration the car was with me, the third one one was shown as permanent; P2137, Accelerator pedal 1 signal coherence with the 2 accelerator pedal signal.

Having cleared the fault it reappeared a few minutes later whilst idling. When reading parameters and pressing the accelerator pedal the % movement appeared smooth and linear on L:exia both pre and post fault clearing hence I'm looking for further pointers as I've never dabbled with a C3.

Anyone got any clues other than there being a dodgy connection 'somewhere' i.e. where exactly etc. Normally I'd have a good poke around but as I'm semi invalided ATM with a slipped disc, crawling around in footwells in the hope of finding something isn't really a sensible option for me, just hoping someone has somewhere to point me towards.

Hi,

We had very similar symptoms from our C3 Hdi 16v. Did the light come back on again when you blipped the throttle? We reset the light and it idled for 10 mins, no light. as soon as we blipped the throttle it came on.

Had codes read and it showed an accelerator pedal related fault. Citroen quoted £105 for repair, about £60 for the part. Got local garage to do it as time was tight for about £15 less which wasnt bad. They replaced the whole pedal unit, comes with the pedal on it. Fault has not reappeared in about 4 weeks and car is back to how it should be.

Hope this of some help to you

Andy

Thanks for that Andy, that's a good pointer in the right direction, you wouldn't by any chance have a part number would you?

Hi sorry been a way for a while. I dont have a part number for it, but it is the part that comes with the accelerator pedal sticking out of it. Any progress with yours?
