This crankshaft speed sensor accurately measures the rotational speed of the engine's crankshaft, providing critical data to the engine control module (ECM) for fuel injection and ignition timing. Manufactured to meet rigorous OEM standards, it ensures precise signal output compared to a worn sensor that may produce intermittent or inaccurate pulses. Operators might experience engine misfires, rough idling, difficulty starting, or the engine stalling unexpectedly when this sensor fails.

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 often first manifests as intermittent engine stalling or difficulty starting. As the failure progresses, the engine may run roughly, misfire, or the check engine light will illuminate with specific sensor-related codes. If left unaddressed, the engine may become completely inoperable, preventing the equipment from performing its work.
Ensure the mounting surface on the engine block is clean and free of debris before installing the new sensor. Be careful not to drop tools or metallic objects near the sensor tip, as this can magnetize or damage it.
Inspect the flywheel or crankshaft reluctor ring for damage or debris that could interfere with the sensor's reading, and check the wiring harness for any signs of chafing or corrosion.
