Keep ignition and fuel timing on point with the Standard Ignition Engine Crankshaft Position Sensor PC237, specially engineered for BMW vehicles. It drops in as a direct-fit replacement for many BMW vehicles, among them the 1994-1995 BMW 850CSi, 1988-1994 BMW 750iL, and 1993-1994 BMW 850Ci; see the Buyer's Guide tab for the full list. The sensor reads the crankshaft's target wheel and reports position and speed to the engine control module, which the ECM uses to time spark and fuel delivery.
- Accurate Timing: Custom magnetic circuit programming and performance testing establish precise calibration between the target wheel and the sensor output.
- Superior Operation: Built with an integrated analog-to-digital converter and adaptive switch points for quick processing to help the ECM adjust fuel and timing.
- Extensive Testing: End-of-line checks for timing, pulse width, and signal amplitude, plus in-lab vibration and extreme-temperature testing.
- Vehicle Performance: Engineered for accuracy, speed, and durability to support proper fuel economy, emissions, and performance.
Signs the original crankshaft position sensor may need replacing include hard starting, stalling, intermittent misfires, or a crank-no-start condition. Diagnose the cause before replacing, since these symptoms can have other sources; if a failed crankshaft sensor is the cause, this PC237 replaces it.
