What is a Crankshaft Position Sensor all about?
Many newer cars have computerized engine management systems that rely on sensors to report data to the computer. The crankshaft position sensor is used in conjunction with the camshaft position sensor to control ignition timing and to let the computer know when to inject fuel and provide spark sequence. Due to the mounting locations of this sensor, it is common for heat and oil leaks to cause this sensor to fail.
How it's done:
- Scan the car for trouble codes.
- Remove and replace crankshaft position sensor.
- Clear trouble codes.
- Check for the proper operation of the car.
What common symptoms indicate you may need to replace the Crankshaft Position Sensor?
- Car does not start.
- Check engine light is on.
- Car misfires (car runs rough).
