P0A25

What it means

The generator torque sensor reports a circuit high fault. Generator torque feedback is unreliable. 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?

This code can put the vehicle into limp or reduced-power mode. Avoid extended driving and have the vehicle diagnosed promptly.

Most likely causes

• Torque sensor failed

  high

  One of the most commonly reported causes for this code — check this first.

• Wiring fault

  medium

  A plausible cause — test and verify before replacing parts.

• Connector pins corroded - high contact resistance

  low

  Less common, but worth ruling out after the more likely causes.
