Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.

It sounds like the code is for a shorted throttle pedal circuit and you have already replaced the throttle pedal trying to resolve this issue here.If the code is still coming up then what needs to be checked from here is to see if there is any shorted wiring leading from the pedal sensor to the engine computer.If there is any shorted or damaged wiring this will cause this fault and the wiring will need to be repaired to resolve this fault here.

Now if all wiring is found to be o.k. and the sensor/pedal assembly was already replaced then I suspect the fault is in the engine computer itself and it will need to be replaced to resolve this fault.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service, your 5-star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete

what is involved and what cost to replace engine computer?
UK Auto Mechanic: Peter Zavarelli,
 replied 8 months ago

If it leads to a faulty engine computer the cost can run over $500 to have it replaced and it will have to be programmed by a dealer when it is replaced.Labor can run around 1 to 2 hours on top of the cost of the computer to have it replaced and programmed.

Let me know if you need anything else and feel free to rate my help here or above ( should be a link to click on ) as this is how I receive credit for my time, this can be done at any time and you can still come back here and reply if needed.Your 5-star rating is appreciated

Thanks Pete
