Diesel Intake Air Flow Position Sensor Minimum/Maximum Stop Performance
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 diesel intake throttle position sensor does not reach the calibrated minimum or maximum stop value during a self-test sweep — typically sensor wear, mechanical stop misalignment, or a sticky throttle plate.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
