I wonder if anyone can help with this one ? I have a 2001 Peugeot 306 HDI 2.0 with the error code P0220 Throttle position sensor error. I have had a couple of these changed in the past after which the error went away for a while, 10 months was the longest. I can't believe 2 sensors have failed, so think the problem lies elsewhere. I have read about a wiring modification that can help with this problem, to do with the air flow sensor. So can you tell me which wires require modifying, I believe it to be a couple of earths that need sorting. At present when the fault triggers the orange management light the car goes into limp home mode which usually lasts for a few minutes and then the car drives as normal. Thanks .
