Track down that hard-to-diagnose M3 sensor fault with the Standard Ignition Engine Crankshaft Position Sensor (PC438), a direct-fit replacement for the 1994-1995 BMW M3. This sensor monitors the rotational position and speed of the crankshaft and feeds that signal to the engine control module, which the ECM uses to manage fuel delivery and ignition timing.

  • Accurate Timing: Custom magnetic circuit programming and performance testing provide precise calibration between the target wheel and the sensor output.
  • Extensive Testing: End-of-line testing for timing, pulse width, and signal amplitude, plus in-lab vibration and extreme-temperature testing, for reliable performance.
  • Superior Operation: Integrated analog-to-digital converter with adaptive switch points for quick processing to adjust fuel and timing.
  • BMW-Specific: Specially engineered for BMW vehicles and designed to support fuel economy, emissions, and performance.

Signs this part may need replacing include a no-start, intermittent stalling, or hesitation. If a failed crankshaft position sensor is the cause, this unit replaces the original; diagnose the fault before ordering.
