Driving on the motorway at the weekend my glow plug light started flashing at me. I pulled over when I could and scanned the car with OBD Eleven and got a P2102 Throttle Actuator Control Circuit Low. The fault wouldn't clear and the car was in limp mode as it was extremely sluggish to accelerate. I carried on my journey and after an hour or so the engine management light also came on. I scanned again and this time it let me clear it, but it came straight back on again after a few feet of driving (both the flashing glow plug and the EML). When I got to where I was going, I parked up, left it for an hour or so then went back out to it, cleared the fault and left it over night. The next day, the car started and drove fine and got me all the way back home without any issue.

 

Any ideas? Anything to take off and clean? Any particular connectors to check?

 

thanks

Oh - our friend P2102 - its your accelerator pedal.  The Potentiometer has failed/is failing.

You need to replace the pedal itself.  Its highly unlikely that the connector for the pedal is not connected, but none-the-less, worth checking,
