This Crankshaft Speed Sensor is essential for the engine's timing and fuel injection system, accurately measuring the rotational speed and position of the crankshaft to inform the ECU. It is constructed with high-quality magnetic components and durable housing to withstand engine vibrations and heat, providing a reliable signal unlike a worn sensor that may produce intermittent or incorrect readings. Operators may observe engine misfires, rough idling, difficulty starting, or the check engine light illuminating when this sensor begins to malfunction.

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.
A failing crankshaft speed sensor can initially cause intermittent engine stalling or rough idling. If the problem persists, the engine may become difficult to start or refuse to start altogether, often accompanied by a check engine warning light. Continued operation with a faulty sensor can lead to poor fuel economy and potential damage to the catalytic converter due to uncombusted fuel.
Ensure the mounting surface on the engine block or flywheel housing is clean and free of debris before installing the new sensor. Avoid using excessive force when tightening the sensor, as this can damage the threads or the sensor itself.
Inspect the crankshaft reluctor wheel for damage or contamination when replacing the crankshaft speed sensor.
