Common Symptoms For Citroen 10+hp P0C02

  1. Unlike other diagnostic codes, this type of code can sometimes be best left to a professional simply because of the bulk of circuitry involved
  2. Test the wiring and connectors at the fuel shutoff valve to make sure that voltage and ground readings are near battery voltage
  3. Pay particular attention to wiring and connectors that have been contaminated due to engine oil or transmission fluid leaks, burned on hot exhaust pipes, or damaged due to road debris. Inconsistencies between the input and output speed sensor readings may be interpreted by the PCM as a transmission friction element application malfunction
  4. The sensor is of the electro magnetic design and uses a reluctor ring (or a specialized set of splines) on the input shaft as reference points
