Code result

P070D

Transmission Fluid Level Sensor Circuit High

High severity

What it means

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.

Is it safe to drive?

No — stop driving

This code points to a problem that can cause damage or affect safety. Avoid driving and have the vehicle diagnosed promptly.
