Fuel Temperature Sensor 2 Out of Range
Fuel temperature sensor 2 is reporting a temperature outside normal range.
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 fuel temperature sensor measures how hot the fuel is, and when it's off by too much, it sends a warning to the engine computer that something might be wrong, like the fuel boiling or being too cold.
What the computer is actually seeing
The engine control module (ECM) sees a voltage signal from the fuel temperature sensor that is either too high (above 150°C or 302°F) or too low (below -40°C or -40°F). This could indicate a short circuit or a broken sensor.
What a healthy reading looks like
Fuel temperature should typically range from -40°C to 85°C (-40°F to 185°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 the wiring and connectors for the fuel temperature sensor for any visible damage or corrosion. Clean or repair as necessary. Decision: If wiring is good, go to step 2. If damaged, repair/replace as needed and retest.
Common causes
- Faulty fuel temperature sensor
- Wiring issue (short or open)
- Corrosion in the connector
- Faulty ECM or software issue
