102-2240 Temperature Gp Sensor — Cat 990

This temperature sensor assembly monitors the engine coolant temperature and sends vital data to the engine control module (ECM) or gauge. It is designed for accuracy and durability in harsh operating environments, ensuring the ECM can properly manage fuel injection and fan speeds. Operators may notice inaccurate temperature readings on the dash, the engine overheating without warning, or diagnostic trouble codes related to temperature 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

The first symptom of a failing temperature sensor is often an erratic or incorrect reading on the engine temperature gauge. If the sensor fails completely, the engine may overheat without any warning indication, potentially leading to severe engine damage due to lack of operator intervention. The ECM may also trigger fault codes, affecting engine performance.

Installation Tip

Ensure the sensor port on the engine block or cylinder head is clean and free of corrosion before threading in the new sensor. Do not use excessive force, as this can damage the sensor threads or the engine block.

Service Note

When replacing the temperature sensor, it is a good practice to check the coolant level and condition, and inspect the radiator and fan for proper operation.
