The CKP sensor is installed to the left side of the rear of the cylinder block. The sensor rotor is fixed on the crankshaft. There are 56 notches spaced 6° apart and a 30° opening. Top dead center of cylinder No. 1 can be detected through this opening. The CKP sensor is a magnetic resistance element type sensor, and generates a square wave signal pulse. The sensor has the following circuits.
The ECM monitors the signal pulses of the CKP sensor and the CMP sensor to make sure they correlate with each other. If the ECM receives a certain amount of CMP sensor signal pulses with no CKP sensor signal pulses detected, the DTC is set.
