Product Overview
Extended cranking, intermittent stalling, poor response, or a cam-signal fault can come from this sensor, but damaged wiring, low system voltage, incorrect mechanical timing, and crank-sensor faults can produce related symptoms. Confirm the code and live signal before service.
The sensor tells the engine computer which cylinder is approaching its firing event so injection and ignition can be synchronized. Connector, lead length, mounting ear, O-ring, sensor depth, engine code, and production date must match.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, connector, dimensions, installed options, and previous repairs can affect fitment. Compare the original component and reference information before purchase.
Frequently Asked Questions
Q: Can a crankshaft sensor cause similar starting symptoms? A: Yes. The ECU needs both crank and cam information, so diagnose the stored code and live data.
Q: Does this fit a later double-VANOS BMW? A: Not unless its catalog calls for 12141703221; later engines commonly use different sensors.
Q: How do I confirm this is the correct part? A: Match VIN, engine code, production date, 12141703221, connector, lead length, mounting tab, sensor depth, O-ring, and harness routing.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
