Here are some additional details on the location of the camshaft position sensor on a 2001 BMW 325i:
* On the M54 engine, there are two camshaft position sensors: one for the intake camshaft and one for the exhaust camshaft.
* The intake camshaft position sensor is located on the left (driver's side) of the engine, just below the valve cover.
* The exhaust camshaft position sensor is located on the right (passenger's side) of the engine, just below the valve cover.
* Both camshaft position sensors are mounted in a plastic housing that is attached to the cylinder head.
The camshaft position sensor is an important component of the engine management system, and it is important to keep it in good working order. If the CPS is faulty, it can cause the engine to run poorly or stall. It is recommended that you have the CPS inspected regularly, and replaced if necessary.
