Intake Manifold Runner Position Sensor/Switch Circuit (Bank 1)
- Severity

- Drivable — book it in
A fault in the intake manifold runner position sensor circuit on bank 1. This sensor tells the module where the runner flaps actually are, so it can confirm they moved when commanded.
Possible causes
- CommonFailed runner position sensor
- CommonCarbon seizing the flaps, so the sensor correctly reports they are not moving
- CommonCorroded connector or damaged wiring
- CommonBroken linkage between the actuator and the sensor
- PossibleLoss of reference voltage or earth
What you might notice
- Loss of low-speed torque or flat top-end power
- Rough idle
- Hesitation
- Worse fuel economy
- Smoke on a diesel
- Check engine light on
What to check, in order
- Check the flaps move freely before condemning the sensor. A sensor reporting that nothing moved may be telling the truth.
- Check the vacuum hoses first on a vacuum-operated system - a split or disconnected hose is the most common cause and the cheapest to fix.
- Check the flaps and linkage move freely. Carbon seizing them is very common on a diesel used for short journeys, and cleaning is often the whole repair.
- Watch commanded against actual runner position on the live data screen through a sweep.
- Inspect the connector for corrosion and the actuator for damage.
