Chrysler Repair: 2003 Chrysler Sebring Camshaft sensor, camshaft sensor, pulley bolt


Question
The engine light on my car came on and running the troubleshooting came up with the following probable causes cam sensor defective, check connector and wiring to sensor and belt out of time. How do you test the camshaft sensor?

Answer
Hi Crystal,
Unfortunately there are three different possible engines so I can't be precise. If you will tell me the L number then I can tell you for sure. Once you locate the sensor it is matter of attaching a voltmeter to wires which are color-coded for identification, after inserting pins through the insulation of two of the wires and attaching the voltmeter to those pins. Then you turn the ignition key to the run position and you turn the engine with a socket, socket extension, and ratchet using the cranshaft pulley bolt.  The voltage should oscillate between 0.3 volts and some larger number of volts, depending upon which engine that you have, doing that several times per complete revolution of the engine. Failure to show pulsing is synonymous with sensor failure, or it could be a wire has lost its insulation and is shorted to ground or some other wire.  If it doesn't do that pulsing and it isn't a wire,  then the sensor needs to be changed, which is quite easy.
So it all will be clear when you tell me the engine that is involved. You will probably want to do this test after driving it for about as long as it takes to get the check engine light to come on again. Chances are if the sensor is failing it does so when gets hot enough to begin to breakdown. You would need a digital voltmeter check it precisely for function but that should cost no more than about $20.
Also tell me the fault code number that was read out, if you know it.
