Code result

P250C

Engine Oil Level Sensor Circuit Low

Moderate severity

What it means

The oil level sensor signal voltage reads below the lower limit, typically a short to ground or an open at the reference end of the sender. The ECM treats the input as invalid and ignores oil-low warnings until the circuit is repaired.

Is it safe to drive?

Use caution

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

  • Signal wire shorted to ground

    high

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

  • Sender shorted internally

    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.
