Exhaust Gas Recirculation (EGR) Temperature Sensor 2 - Performance Problem
Problem with the performance of the second EGR temperature sensor.
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 second EGR temperature sensor is not providing accurate readings, which can affect how exhaust gases are recirculated back into the engine for emissions control.
What the computer is actually seeing
The computer is monitoring the second EGR temperature sensor voltage (0.5V to 4.5V). If it deviates from expected during operation, the code sets.
What a healthy reading looks like
During normal operation, the EGR temperature should range from 90°C to 200°C (194°F to 392°F).
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.
- 11. Inspect wiring and connectors to EGR temperature sensor for damage or corrosion. Decision: Are they good? Yes: Go to Step 2. No: Repair wiring/connectors and retest.
Common causes
- Faulty EGR temperature sensor
- Damaged wiring or connector
- Blocked EGR passage
- Faulty EGR valve
Typical repair cost
$$$
