Transmission Fluid Temperature Sensor Circuit High
ATF temperature sensor signal voltage above the upper threshold — short to supply or sensor fault. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.

Possible causes
- Sensor circuit shorted to supply high
- Transmission temperature sensor failed medium
- Connector pins corroded - high contact resistance low
Symptoms

- Difficulty: hard
- DIY: shop recommended
- Estimated cost: 80–800 €
- Estimated time: 0.5–4 h
- Component: transmission temperature sensor
- Component: sensor wiring
