P1338 AUDI, VOLKSWAGEN: CAMSHAFT POSITION SENSOR BANK 1 OPEN CIRCUIT OR SHORT TO POSITIVE
The CamshaftPosition Sensor (CMP) is a device that sends information to the Engine Control Module (ECM), which matches the speed at which the camshaft rotates. With the information provided by this sensor, the signal from the CKP Sensor (Crankshaft Position Sensor) is also monitored. With these parameters, the engine timing and fuel injection are controlled and regulated.
When the CMP Sensor does not work properly, a DTC will be set indicating such a situation. In the case of the P1338 OBDII code for Audi and Volkswagen vehicles, it is set if the ECM detects that the CMP Sensor input signal for bank 1 is not within the operating range.
