Walker Products Engine Crankshaft Position Sensor P/N:235-91139
Walker Products 235-1501 crankshaft position sensor for the 1991-1992 BMW 318i 4-cylinder 1.8L and other vehicles tracks how fast the crankshaft turns and where it sits. Often called a crank sensor, it sends that data to the engine control module so fuel injection and ignition are timed correctly.
Hard starting, stalling or a check engine light can mean this sensor is worn, though the camshaft position sensor or the wiring and connector can produce similar symptoms, so find the cause before replacing it. This listing is one sensor, and the engine takes a single one.
This sensor fits the 1991-1992 BMW 318i 4-cylinder 1.8L and the 1991 BMW 318is 4-cylinder 1.8L.
