The crank angle sensor consists of a magnet and a coil and is located near the flywheel ring gear. The sensor sends information to the ECM about the angle of rotation of the crankshaft (piston position). Based on the output signal information from this sensor, the ECM calculates engine speed and crankshaft position.
Examination
1. Disconnect the connector from the crank angle sensor.
2. Measure the resistance between pins 1 and 2 of the sensor connector.
Resistance: 0.486-0.594 kOhm at 20°C
3. If the resistance of the sensor differs from the required one, replace the sensor.
Gap between rotor and crank angle sensor: 0.5–1.5 mm
Tightening torque: 9–11 Nm
