P2023

Intake Manifold Runner Position Sensor/Switch Circuit Intermittent

Moderate severity

What it means

The IMRC position sensor signal on bank 2 jumps or drops out intermittently — usually a loose pin, partially-broken conductor, or moisture in the connector.

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

  • Loose terminal in connector

    high

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

  • Water ingress into connector

    medium

    A plausible cause — test and verify before replacing parts.

  • Connector with intermittent contact under vibration

    low

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