P0E3F

What it means

Voltage on the charge status indicator a control circuit is 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?

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.

Most likely causes

• Wire shorted to ground

  high

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

• Lamp internal 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.
