Study Guide General Description

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

Study Guide 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.Study Guide This CMPS signal is sent to the PCM and it uses CMPS signals for determining the ignition timing with CKPS signals. CMPS makes Sequential Injection possible.

Study Guide DTC Description

If the deviation between CKPS and CMPS(IN-CMPS Bank 1) is bigger than the threshold value, ECM sets DTC P0016.

Study Guide Description

1. General Description

Study Guide The Camshaft Position Sensor (CMPS) is a sensor that detects the compression TDC of the NO. 1 cylinder. The CMPS consists of a hall type sensor and a target on the end of the intake camshaft. When the target triggers the sensor, the sensor voltage is 5V. If not, the sensor voltage is 0V.Study Guide These CMPS signal is sent to the ECM and the ECM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.

2. DTC Description

If there is no change of signal, the ECM judged as a fault and DTC is set.
