P0012 VOLKSWAGEN Meaning

Engine Management Systems (EMS) use the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The EMS constantly monitors the number of pulses on the signal circuit. The EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses, Diagnostic Trouble Codes (DTC) should be stored in the EMS. Some engine management systems will then default to multi-port or gang-fire injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty most engines will start. The EMS misfire diagnostic will likely be affected.
