• Intermittent stalling caused by an unstable engine speed signal
• Rough running from incorrect ignition timing input
• Check engine light concerns tied to crankshaft position sensor faults
• Fuel delivery or spark control issues on BMW engine management systems

Installation Notes and Tips

Verify the connector shape, terminal count, and terminal gender against the original sensor before installation. Confirm the vehicle application by year and model: Fits 1991-1995 BMW 525i, N/A; Fits 1992-1995 BMW 325i, N/A; Fits 1992-1995 BMW 325is, N/A; Fits 1993 BMW 525iT, N/A; Fits 1995 BMW M3, N/A.
