31216677 — Crankshaft Sensor 8S6Q9E731Aa 31216677 For Volvo C30 S40 Ford C-Max Fiesta Mondeo

This crankshaft sensor is a vital engine management component that detects the rotational speed and position of the crankshaft, sending this data to the engine control module (ECM) for precise fuel injection and ignition timing. It is manufactured to meet strict automotive standards, ensuring accurate signal generation unlike a worn sensor that may produce erratic or weak signals. Engine performance issues such as rough idling, stalling, difficulty starting, or a complete no-start condition are common symptoms of a failing crankshaft sensor.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most common initial symptom of a failing crankshaft sensor is an illuminated check engine light, often accompanied by rough idling or intermittent stalling. If ignored, the engine may become progressively harder to start, eventually leading to a complete no-start condition. The engine requires accurate crankshaft position data to run, and its absence will prevent the engine from operating.

Installation Tip

Ensure the engine is completely cool before attempting to remove the sensor, as it is often located near hot exhaust components. Avoid using magnetic tools near the sensor tip, as this can potentially damage its internal components.

Service Note

Inspect the flywheel or flexplate for damage or debris that could interfere with the sensor's reading when replacing the crankshaft sensor.
