Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Crankshaft Position Sensor
The crankshaft position sensor is the hall principle sensor.
Since the crankshaft position sensor is installed opposed to the multi-pulse wheel, pulse signals of 5 V and 0 V are generated during the rotation of crankshaft. ECM transmits a short-resistant engine speed signal via CAN communication based on a signal of crankshaft position sensor.
When ECM can not receive the crankshaft position sensor signal, commute the intake camshaft position sensor signal and exhaust camshaft position sensor signal to enable driving.
