The camshaft position sensors play an important part in the operation of the fuel injection and ignition systems on the car. They are used to give the vehicle's computer a reference point for the timing of the camshafts. This in turn allows the fuel injection, ignition and variable valve timing systems to operate correctly.

A failing cam sensor can cause rough running, poor throttle response and in some cases will prevent the engine from running altogether. When a cam sensor fails, it usually triggers a fault code related to the sensor that isn't working correctly. You'll need to use a diagnostic scanner, such as VADIS to read the fault code, determine which side is bad and then determine your next course of action.

Replacing both the camshaft position sensors is easy. They are held in place with a single 8mm bolt. You'll need to remove the upper intake tube as well as the cylinder head cover to access both camshaft position sensors. See our article on Spark Plug and Coil Pack Replacement for more information.

Shown here are the camshaft position sensors (CPS) for the intake camshaft (green arrow) and also the exhaust camshaft (yellow arrow).
Figure 1

Shown here are the camshaft position sensors (CPS) for the intake camshaft (green arrow) and also the exhaust camshaft (yellow arrow). The same sensor is used for both sides so don't worry about mixing them up. We'll focus on the intake side in this instance. The procedure is the same for the exhaust side.

Press the tab (green arrow) on the electrical connector and pull it off the CPS.
Figure 2

Press the tab (green arrow) on the electrical connector and pull it off the CPS. Loosen and remove the 8mm bolt (blue arrow) holding the CPS in the mounting bore and pull it straight up and out. You may need to use a bit of force to get it out.

Shown here is the CPS removed from the engine.
Figure 3

Shown here is the CPS removed from the engine. Installation of the new CPS is the reverse of removal.
