295-4636 Speed Sensor — Cat 3508 3516

This speed sensor accurately measures the rotational speed of the engine's crankshaft or camshaft, providing critical data to the engine control module (ECM) for precise fuel injection and ignition timing. Manufactured to meet strict OEM specifications, it offers reliable signal output compared to a faulty sensor which may produce intermittent or incorrect readings. Operators may experience engine misfires, rough idling, stalling, or the illumination of the check engine light when this sensor begins to malfunction.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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 speed sensor is often intermittent engine performance issues, such as rough idling or hesitation during acceleration. If the sensor fails completely, the engine may refuse to start or stall unexpectedly, and the check engine light will likely illuminate. Continued operation without a functioning speed sensor will prevent the engine from running correctly, potentially leading to damage from incorrect timing.

Installation Tip

Ensure the sensor's mounting surface is perfectly clean and free of metal shavings or oil before installation. Avoid overtightening the sensor, as this can damage the threads or the sensor housing.

Service Note

When replacing a speed sensor, it is advisable to inspect the wiring harness for any signs of damage or corrosion and check the condition of the associated trigger wheel or reluctor.
