Hi all,

Working today on a friends 2001 Octavia. Problem was the accelerator stopped working,  there is no response at all when the accelerator is pressed no revs etc and EPC light on.

 He updated he has had a new throttle body sensor and accelerator pedal unit fitted but this made no change. The car starts and is good condition for the age.

 

SO I scanned it with VCDS Lite full prog and re set the throttle (unit 060 on vcds)  so its correct, We also replaced the accelerator pedal unit and it still  the same.

Im not an expert with this software and I did get the other codes from the system here they are.

 

Accelerator Position Sensor   (G79) :Signal too high P1631 - 35-00

Accelerator Position Sensor  2 (G185) : Signal too high P1634 35-00

Oxygen (lambda) sensor Heating B1 S2 Open circuit P1118 35-00

Mass Air Flow Sensor (G70) : Signal too low P0102 35-00

 

We were trying to get the car the rev so it can be moved.  So can the throttle pedal also need programmed in if so can this be done on vcds?

so need also advice on how to check the plug voltage on accelerator to verify if its got correct feed which I think should be 5 Volts.

As well as guidance from those who know more about these faults,

 

Thanks

 

 

 

 

 

Ok, do you have any warning lights? Is it running at idle or stuck at fast idle speed?

EPC light is on and it is stuck at idle speed.

thanks

That still sounds like a throttle problem, although I'd have expected the ECU to select "limp mode" and hold the engine at fast idle for a pedal fault.

Did you solve this?  I’ve just limped home in fast idle (1200rpm) with the ignition coil warning light on.  Can anyone help?  No response to the throttle pedal. If I killed the ignition it would drive normally for 10sec..1min the back to limp home mode...  Any Ideas, local friendly garage in the morning.  180000miles and going strong until this issue ;-(

Same, it happened after changing Oxygen Sensor. Any advice?
