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

A failing induction sensor may initially cause intermittent engine misfires or a slight hesitation during acceleration. If left unaddressed, the engine may begin to stall frequently, especially at lower RPMs. Continued operation with a faulty sensor can lead to diagnostic trouble codes and potentially prevent the engine from starting altogether.

Installation Tip

Ensure the sensor's mounting surface on the engine block or flywheel housing is perfectly clean to guarantee proper air gap and signal integrity. Avoid overtightening the sensor during installation, as this can damage the threads or the sensor housing.

Service Note

Inspect the flywheel or crankshaft reluctor ring for damage or debris that could affect the sensor's reading.
