This is a crankshaft position sensor, vital for engine management as it detects the rotational speed and position of the crankshaft, sending this information to the ECU for precise ignition timing and fuel injection. Manufactured to meet strict OEM quality standards, it ensures accurate data transmission, unlike a worn sensor that can cause engine performance issues. Operators may experience rough idling, stalling, or a no-start condition if this sensor malfunctions.

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 first noticeable symptom of a failing crankshaft position sensor can be an illuminated check engine light or intermittent engine stalling. If the sensor fails completely, the engine may refuse to start, as the ECU will not receive the necessary timing information. Continued operation with a faulty sensor can lead to poor fuel economy, rough running, and potential damage to other engine components due to incorrect timing.

Installation Tip

Ensure the sensor mounting surface on the engine block is clean and free of debris before installation. Avoid using magnetic tools near the sensor tip, as this can interfere with its magnetic field and affect its function.

Service Note

Inspect the engine's flywheel or flexplate for damage or missing teeth when replacing the crankshaft position sensor.
