The camshaft position sensor in your Mitsubishi Eclipse plays a huge role in how your engine operates. This is a basic hall effect style sensor that reads the teeth on your camshaft. Your Eclipse engine computer then uses this positioning signal to deliver the right amount of fuel, and control the spark events properly.

When the Eclipse cam sensor fails, your Mitsubishi will suffer from a wide range of different issues. One of the most common cam sensor problems is when your Eclipse won't start. Lack of signal from your Eclipse cam angle sensor can cause this to happen.
