P0019 - CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION (BANK 2 SENSOR B)
POST UPDATED IN February, 2023
Description of DTC code P0019 Generic
The CMP Sensor (Camshaft Position Sensor) and the CKP Sensor (Crankshaft Position Sensor) work together to monitor fuel delivery and timing. Both sensors consist of a reluctor ring that rotates over a magnetic sensor. The magnetic sensor generates voltage and shows the position of each sensor.
The CMP Sensor signal is used by the vehicle’s computer to identify the start of the injector sequence. The signal from the CKP Sensor detects the position of the crankshaft relays and controls the spark timing. These sensors are linked by a timing belt or chain. For this reason, it is necessary that both the cam and the crank are precisely synchronized.
If the PCMfinds that these signals are located out of time by a specific number of degrees, the DTCP0019 OBDII code will be set.
