Exhaust Gas Temperature Sensor 2
This code indicates an issue with Exhaust Gas Temperature Sensor 2.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The exhaust gas temperature sensor measures how hot the exhaust gases are. If it detects temperatures outside normal range, there's likely a fault with the sensor or the exhaust system.
What the computer is actually seeing
The ECM expects the Exhaust Gas Temperature Sensor 2 to report specific temperature ranges, generally between 200°C to 900°C (392°F to 1652°F).
What a healthy reading looks like
Normal operating range for EGT Sensor 2 should be between 200°C and 900°C. Readings above 900°C may indicate a fault or sensor failure.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check for any visible damage to Wiring and connectors associated with Exhaust Gas Temperature Sensor 2. Correct if found.
- 2Using a multimeter, check the resistance of the EGT Sensor 2. Expected range should reflect resistance consistent with temperature (about 0.5 to 5 kΩ at normal operational temperatures).
- 3Start the engine and observe the EGT Sensor 2 output using a scan tool. Ensure it's within the expected temperature range (200°C to 900°C). If it’s faulty, replace the sensor.
- 4Check for exhaust leaks around the sensor that could affect readings. Fix if present.
Common causes
- Faulty Exhaust Gas Temperature Sensor 2
- Wiring issues or shorts in EGT sensor circuit
- Excessive soot or damage in the exhaust system
- Faulty ECM or corrupted data from sensor

Frequently asked questions
Is it safe to drive with this code active?
Moderate severity indicates you should address this soon, but the vehicle is usually drivable unless there are obvious performance issues.
Will this code come back after I clear it?
Possibly, especially if there's an underlying issue with the sensor or its circuit.
Why does this code pair with others?
Multiple codes can indicate broader issues within the exhaust or emissions systems, so addressing one may impact others.
