20497219 — Exhaust Gas Temperature Sensor 20497219 577.96524 For Volvo Truck Vn Vnl 2000–2005

This Exhaust Gas Temperature (EGT) sensor measures the temperature of exhaust gases exiting the engine, providing critical data for engine management and emissions control. It helps the engine control unit (ECU) optimize combustion and prevent overheating by monitoring exhaust temperatures, unlike a failed sensor which can lead to inaccurate readings or no readings at all. Symptoms of a faulty EGT sensor include illuminated check engine lights, reduced engine power, or increased exhaust smoke.

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 exhaust gas temperature sensor may initially trigger a check engine light or cause the engine to enter a reduced power mode. If the sensor fails completely, the ECU will not receive temperature data, potentially leading to improper fuel mixture and increased exhaust temperatures, which can damage the turbocharger or catalytic converter. Continued operation with a faulty EGT sensor poses a risk of severe engine damage due to uncontrolled thermal stress.

Installation Tip

Ensure the exhaust system has cooled completely before attempting removal to avoid severe burns. Apply anti-seize compound to the threads of the new sensor to facilitate future removal, but be careful not to get any on the sensor tip.

Service Note

When replacing the EGT sensor, inspect the exhaust system for leaks and check the turbocharger for proper operation.
