CRANKSHAFT POSITION (CKP) SENSOR OPERATION [MZR-CD (RF Turbo)]
BME014018220T04
• The pulsar has 23 teeth, missing one tooth in one location, and detects the pulsar rotating angle per 15° CA.
• When the pulsar rotates, the magnetic flux that passes the coil increases/decreases and alternating voltage is generated.
• The CKP sensor detects the pulse (alternating voltage) generated by the projection on the pulsar in the back of the crankshaft pulley and outputs this to the PCM as a crank angle standard position signal.
• The PCM detects the engine speed by counting the pulses.
