Intermittent rough idle, ran Forscan no DTC Code but shows CMP fault. Checked
the CMP resistance with 990 ohms result, this is a little above the specified 800-900 ohms. Despite the annoying idle issue the car is performing well and good on fuel. Have changed out most of the likely suspect items inlet gasket, 02sensor, IAT ,filters ,fuel pump, Reg, injectors, cleaned T/B and ISC. Approx week ago Forscan indicated P0325 knock sensor code and I removed and retightened the sensor in a slightly different orientation and code has not returned. Is the 990 ohms for the CMP acceptable or does it need to be replaced. Cheers |
