BMW Electrical Sensors, Switches, & Relays for BMW Z3 (1996-2002)

Clear BMW chassis

Please ensure your correct model is selected

Electrical gremlins can be very frustrating. Luckily your BMW's electrical system is better than most, even if it's 25 years old. Here you will find electrical relays, sensors, switches, and modules for the engine, camshaft, and crankshaft. Our parts are OEM, Genuine BMW, or approved aftermarket brands that we have an excellent track record with. There is no middle ground with electrical parts - it either works perfectly or not. And there's nothing more frustrating than a new part that fails right out of the box. So it's important to choose quality replacement parts over a cheap but faulty piece.

Located on the intake side of the cylinder head, this sensor relays the position of the camshaft to the computer in order to determine proper ignition timing. When this sensor fails the engine will generally log a fault code and may place the vehicle into "limp" mode. When this happens it is advised to stop driving the vehicle and address the issue immediately as premature wear or long term damage to the engine is possible.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

Sensor for: Exhaust. One weak point on BMW engines for years has been the cam position reference sensor. On the S54 engine in the E46 M3, M Roadster, and Z4M, there is one sensor for each cam. The sensor tells the computer the position of the cam on cylinder #1. The computer relies on the sensor's information to set injection timing and VAN0S control. When a sensor goes bad, the computer loses track of what position the cam is in. While the engine will continue to run (taking its measurements from the crank position sensor), the entire system is thrown off. The engine may stumble or run rough, but not misfire, and there will be a loss of performance. Each cam sensor also doubles as a sensor for the VAN0S. So when the sensor goes bad, the VAN0S will revert to a safe mode and will not advance.

While the engine will still run with a faulty cam position sensor, it's not running in its finest tune. The DME will have fault codes related to the cam sensor or for the VAN0S. This is the Original BMW sensor with a new o-ring.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This is a remanufactured alternator that includes a $50.00 refundable core charge.
