    Service description

    What is the camshaft sensor?

    It is one of the most important sensors in the modern car. It feeds the engine controller with information on the current position of the camshaft. The valve control mechanism position is determined based on this information. In addition, the camshaft sensor also provides the onboard computer with information on whether the engine is on or off.

    When should the camshaft sensor be replaced and how is it done?

    A camshaft sensor failure results in unstable operation of the engine and may even disable it altogether. Changing the sensor requires disconnecting it from the electrical system and removing the bolts holding it to the cylinder head. Next, a new sensor is fitted and connected to the electrical system.

    What else to keep in mind?

    After changing the sensor remember to cancel the error codes stored in the engine controller after the failure by means of a diagnostic scanner. If fitted properly, a new sensor should restore correct operation of the engine. The sensor itself is not repairable and cannot be reused in the event of a failure.
