Camshaft Position Sensor
The camshaft position sensor measures the rotational position of the camshaft and transmits that information to the engine control computer.
Symptoms of Wear or Failure
- Problems starting the car
- Engine may shut off or die intermittently
- Engine may misfire or hesitate on acceleration
- Check Engine Light may illuminate
Related Repair Advice
- The camshaft position sensor is commonly mounted on the cylinder head or timing cover; on some older engines, it is mounted inside the distributor
- Whenever a camshaft position sensor is replaced, be sure to verify the alignment of the timing belt/chain to make sure there is no fluid leaking onto its mounting area
- Always use a factory OEM camshaft position sensor and be sure to check for any relevant Technical Service Bulletins (TSB), necessary software updates, and re-calibration procedures
- A camshaft position sensor code isn't always triggered by a defective camshaft position sensor. It can be triggered by other issues, such as a worn timing belt or timing chain, or a defective ignition module, crank shaft position sensor, or mass air flow sensor.
