Hello again,

Thank you for your reply...

After a sensor is fitted - such as your camshaft sensor- the fault codes need to be re read - and the code deleted.. the light should then be off.

If its not going off - and keeps coming on - then if its the same code as well that keeps coming back, the wiring on that circuit needs to be checked - from the sensor - back to the Ecu ( computer ) and the connections checked for corrosion etc - anything like that will cause the light to stay on - with that fault code.

If its not that - then the most likely cause of that would be a loose or worn timing belt.. The cam sensor monitors the position of the camshaft in relation to the crankshaft ( timing etc )... if the belt is loose or worn, and there is no faults on the sensor itself or circuit - the belt is the suspect then - that would have to be checked / renewed then to cure this fault.

Im very pleased to have helped / advised you - ..
