Buyers Guide (Reference Year/Make/Model search for proper fitment): Compatible with BMW-318I, 318IS, 318TI, Z3 (99-96) 100% environmental, endurance and end-of-line testing for Timing, Pulse Width and Signal Amplitude ensures consistent product reliability.Advanced circuitry protects the system from stray electro-magnetic fields and power spikes. Integrated A/D converter and digital signal processing with a dynamically adaptive switch point improves accuracy and operation.Custom magnetic circuit programming calibrates the sensor during performance testing, which improves timing accuracy between target wheel and sensor output. Located in the Engine Oil Pump system, the Crank Position Sensor is a critical Engine-Fuel part. It plays a crucial role by monitoring the speed and position of the engine crankshaft. This information is sent to the engine control unit (ECU), which adjusts the fuel injection and ignition timing accordingly. If the Crank Position Sensor becomes aged, broken, or clogged, it could result in poor engine performance, reduced fuel efficiency, or even lead to engine failure.
