109-4367 Exhaust Gas Temperature Sensor — Cat 3508 3512

This Exhaust Gas Temperature (EGT) sensor measures the temperature of exhaust gases exiting the engine, providing vital data for emissions control and engine performance monitoring. Built to OEM standards, it ensures accurate temperature readings, unlike a failing sensor that can cause inaccurate ECU calculations. Operators may observe a check engine light, reduced engine power, or increased exhaust smoke as common symptoms of a malfunctioning EGT sensor.

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 initial sign of a faulty EGT sensor is often a diagnostic trouble code or an illuminated check engine light. If ignored, the engine's performance may degrade, leading to reduced power output and potentially increased fuel consumption or exhaust emissions. The primary risk is damage to the engine or emissions control system due to improper temperature management.

Installation Tip

Ensure the exhaust manifold threads are clean and free of carbon buildup before installing the new sensor. Apply anti-seize compound sparingly to the sensor threads to prevent seizing in the future.

Service Note

Inspect the exhaust system for leaks and check the turbocharger for proper operation when replacing the EGT sensor.
