212-3426 Speed Sensor — Cat Engine 3516C 3512E

This is a CAT Speed Sensor, an electronic component that monitors the rotational speed of the engine's crankshaft or camshaft, providing critical data to the engine control module (ECM). Manufactured to precise specifications, it ensures accurate speed readings for optimal engine performance and fuel management, unlike a faulty sensor that sends erratic signals. Operators may observe a check engine light, engine stalling, or poor engine performance if this sensor fails.

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

A failing speed sensor may initially cause the check engine light to illuminate with intermittent engine speed signal errors. If the sensor fails completely, the engine may stall unexpectedly or refuse to start, as the ECM lacks essential operating data. Continued operation without a functioning speed sensor can lead to incorrect fuel delivery and potentially damage the ECM.

Installation Tip

Ensure the mounting surface for the speed sensor is clean and free of metal debris before installation. Do not use excessive force when threading the sensor into its bore, as this can damage the threads or the sensor itself.

Service Note

When replacing a speed sensor, it is good practice to inspect the crankshaft or camshaft reluctor wheel for any damage or foreign material.
