How to Replace a Camshaft Position Sensor on a MB C280

1. Park the vehicle on a flat surface and turn off the engine. Apply the parking brake and open the hood. Let the engine cool for at least 1 hour.
2. Locate the camshaft sensor. It is bolted to the front of the left cylinder head. It is made from black plastic and has a two-wire connector attached to it.
3. Disconnect the sensor's electrical connector and remove the bolt holding it to the cylinder head with a 3/8-inch ratchet and a 10 mm metric socket.
4. Remove the sensor from the cylinder head using a twisting and pulling motion. Install the new camshaft sensor into the cylinder head using a twisting and pushing motion.
5. Reinstall the sensor's retaining bolt and reconnect its electrical connector. Start the engine and confirm that it operates properly.
