DTC P0016: Crankshaft Position-Camshaft Position Correlation (Bank 1 Sensor A): General Description

A Crankshaft Position Sensor (CKPS) is a hall type sensor that generates voltage using a sensor and a target wheel mounted on the crankshaft. The ECM calculates engine RPM by using the sensor' s signal and controls the injection duration and the ignition timing.

Camshaft Position Sensor (CMPS) is a hall sensor and detects the camshaft position by using a hall element. It is related with Crankshaft Position Sensor (CKPS) and detects the piston position of the each cylinder which the CKPS can't detect. This CMPS signal is sent to the ECM and it uses CMPS signals for determining the ignition timing with CKPS signals. CMPS makes Sequential Injection possible.
