Camshaft Position Sensor Replacement
How are camshaft position sensor issues diagnosed?
Using a scan tool, a mechanic can read where the computer believes the crankshaft and camshaft are, and compare that information to their actual position. If the reading is incorrect, the position sensor will be tested, and replaced if necessary.
How is a camshaft position sensor replaced?
Replacement of the camshaft position sensor is completed by disconnecting the electrical connector or connectors and unscrewing the sensor. If required, sealant will be applied before inserting the new sensor into the engine. Finally the electrical connector is connected, and the vehicle is tested to confirm the repair.
There are two common locations for the camshaft position sensor: inside the timing cover and near or on the engine's valve cover.
RepairPal recommendations for camshaft position sensor issues
When replacing the camshaft position sensor, make sure there are no obvious oil or coolant leaks that could ruin the new sensor.
High-quality sensors â preferably OEM parts â should be used, as lesser products will likely lead to a repeated repair. Also, the vehicle's timing belt should be inspected at this time. If the timing belt or timing chain has failed, it will need to be replaced.
Can I replace the camshaft position sensor myself?
Diagnosis is key when it comes to sensor replacement, as other problems could cause the same symptoms. If the issue can't be diagnosed at home, a professional technician should be trusted with the issue.
