P070D
Transmission Fluid Level Sensor Circuit High
Same as P070A with the signal voltage above the plausible range. 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
- Signal shorted to supply high
- Connector pins corroded - high contact resistance low
- Supply wire pinched against B+ source low
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Inspection / repair
- Difficulty: medium
- DIY: shop recommended
- Estimated cost: 200–800 €
- Estimated time: 1–3 h
- Component: transmission fluid level sensor
- MIL / check engine light
