Camshaft Position Sensor

By Andy Y, September 26, 2008

The camshaft position sensor measures the rotational position of the camshaft and transmits that information to the engine control computer.

Symptoms of a Bad or Failing Camshaft Position Sensor

  • Problems starting the car
  • Engine may shut off or die intermittently
  • Engine may misfire or hesitate on acceleration
  • Check Engine Light may illuminate

Camshaft Position Sensor 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.

I have a 2010 malibu lt and check engine light is on said cam/crankshaft position sensors need to be replaced. So I did, cleared codes, and engine light keeps coming back on.
