How to Install a Camshaft Position Sensor on a 2002 VW Passat

Volkswagen uses a camshaft position sensor on the 2002 Passat sedan to relay information about the camshaft position and engine speed to the electronic control module to determine ignition timing and fuel injection synchronization. Located on the cylinder head behind the upper timing belt cover on the 1.8-liter engine, the sensor is accessible for removal and replacement. Replace the sensor using basic hand tools.

Instructions

1

Locate the cam position sensor electrical connector on the timing belt cover just to the left of center of the engine. Unlock the connector retaining tab and pull the connector off the sensor.

2

Unlock the upper timing belt cover retainer clip at the top-right corner of the cover. Pull the top of the cover away from the engine slightly and disengage the upper cover from the tab in the lower cover. Lift the upper cover straight up and out of the engine compartment.

3

Remove the two camshaft sensor retaining bolts using a ratchet and socket. Pull the old sensor off the engine.

4

Make certain the tab on the faceplate on the end of the camshaft is properly indexed in its detent. Install the new sensor on the engine. Install the two sensor retaining bolts and torque them to 88 inch-pounds using an inch-pound torque wrench and socket.

5

Position the upper timing belt cover on the engine. Engage the tab in the lower timing belt cover with the slot in the upper timing belt cover. Snap the upper cover into place. Install the camshaft sensor electrical connector and ensure the retainer locks in place.
