P1345 - MAZDA: POSITION SENSOR CAMSHAFT (CMP) - SIGNAL MALFUNCTION
P1345 - TOYOTA: VARIABLE VALVE TIMING SENSOR - LEFT BANK - CIRCUIT MALFUNCTION
P1345 - VOLKSWAGEN BMW: IGNITION AMPLIFIER, PRIMARY CIRCUIT 3 - SHORT TO GROUND
Description of DTC code P1345
A lot of vehicle manufacturers have implemented a variable camshaft timing system in the engine. Through this system, the camshaft is automatically delayed or over-advanced at certain speeds.
The CKP sensor(Crankshaft Position Sensor) is in charge of indicating the ECM (Engine Control Module) the position of the crankshaft concerning the TDC (Top Dead Centre) in the compression stroke in the cylinder. On the other hand, the CMP Sensor (Camshaft Position Sensor) is used. The information transmitted to the ECM is used to determine the best fuel injector timing.
The fault code P1345 OBDII is a manufacturer-specific code, although there is a slight difference in definition between each one. However, this code points to an ignition problem in all vehicles, and its establishment occurs when the correlation between CKP Sensor and CMP Sensor is not within the expected range or is not synchronized.
