P0017 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B) - General Information

Component Location





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.

DTC Description

If the deviation between CKPS and CMPS is bigger than the threshold value, ECM sets DTC P0017.

Signal Waveform & Data








This example shows a typical Crankshaft Position Sensor(CKPS) and Camshaft Position Sensor(CMPS) waveform at idle. The ECM controls the injection and ignition timing by using these signals.
