Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
- Inspect the EGR temperature sensor terminals for corrosion.
- If the EGR temperature sensor signal circuit is shorted to a separate 5-volt source, the DTC will set.
- If the engine has cooled for at least 8 hrs, the scan tool EGR Temperature Sensor and the Engine Coolant Temperature Sensor values should display within 3°C (5°F).
- EGR cooler temperature sensors may fail while operating under extreme temperatures. Review the Freeze Frame/Failure Records to verify the failure criteria.
- With a fault present, the sensor reads a software defaulted value of 200°C (392°F) and does not change with an expected temperature increase or decrease.
