Throttle/Pedal Position Sensor "C" Circuit Intermittent

Moderate severity

What it means

The "C" channel produces an intermittent signal — usually a marginal connector or a worn track inside the pedal sensor.

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.

    A plausible cause — test and verify before replacing parts.

  • Harness routed against vibrating component

    low

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