P0C1E

What it means

The internal temperature sensor reports voltage below the expected window. 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

• Sensor shorted to ground

  high

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

• Internal sensor short

  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.
