Transmission Fluid Temperature Sensor Range/Performance Problem
The transmission fluid temperature sensor is reading outside of its 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 computer monitors the temperature of the transmission fluid to make sure it’s operating at the right heat. If it gets too hot or too cold, it affects how the transmission works.
What the computer is actually seeing
The Engine Control Module (ECM) expects the transmission fluid temperature to be between 160°F and 220°F (71°C to 104°C) under normal operating conditions. If the sensor reading exceeds this range or responds too slowly, it triggers the P0711 code.
What a healthy reading looks like
Normal range: 160°F to 220°F (71°C to 104°C). Faulty reading: below 100°F (38°C) or above 300°F (149°C).
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 the transmission fluid level and condition (should be bright red and not smell burnt). If low, refill to the proper level with the correct type of fluid. Decision point: If fluid was low, top off and retest. If code returns, continue.
Common causes
- Faulty transmission fluid temperature sensor
- Wiring issues or poor connections
- Low transmission fluid level or old fluid
- Faulty engine control module (ECM)

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity; you can drive but should fix it soon to avoid transmission damage.
Could this code come back after clearing it?
Yes, if the underlying issue isn't fixed, it can return.
Why does this code pair with other codes?
Related codes often indicate issues with the same system or sensor, like wiring or fluid conditions.
