Usually safe to drive short distances, but the fault will not clear itself and can worsen or fail an emissions test.
Intake Manifold Runner Position Sensor/Switch Range/Performance (Bank 1)
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The IMRC position sensor on bank 1 reports a value, but it does not match the commanded flap state — for example, the flap is commanded closed yet the sensor still reads open. Common on engines where the connector pin clip wears out and the sensor reads erratic positions.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
