Transmission Fluid Temperature Sensor Range/Performance Problem
The transmission fluid temperature sensor is providing an incorrect reading.
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 transmission fluid temperature sensor is supposed to measure how hot the transmission fluid is but it's sending back readings that don't make sense.
What the computer is actually seeing
The ECM expects the transmission fluid temperature to be between 70°F and 220°F. If it sees values below 10°F or above 240°F, it triggers the P0715 code.
What a healthy reading looks like
Transmission fluid temperatures should normally be between 160°F and 220°F under typical driving conditions.
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. Check the transmission fluid level. Fill if low and retest.
- 22. Inspect the wiring and connectors related to the transmission fluid temperature sensor for damage or corrosion.
- 33. Use a scan tool to check the current transmission fluid temperature reading against expected values (160°F-220°F). If it reads incorrectly, proceed to step 4.
- 44. Disconnect the transmission fluid temperature sensor and test the sensor with a multimeter on a temperature controlled environment or heat source. Confirm resistance values fall within manufacturer specifications. If out of range, replace the sensor.
- 55. Clear the code and take the vehicle for a test drive to see if the code returns.
Common causes
- Wiring issues or short circuits in the sensor circuit
- Faulty transmission fluid temperature sensor
- Poor connector contact or corrosion at the connector
- Low transmission fluid level affecting sensor readings

Frequently asked questions
Is it safe to drive with this code active?
It can be safe but it's not recommended as incorrect temperature readings can lead to transmission damage.
Will this code come back after I clear it?
If the underlying issue is not fixed, yes, it will likely return.
Why is this paired with other P071X codes?
These codes all relate to transmission temperature sensing and circuit performance issues.
