Not urgent
Unlikely to affect driveability. Worth resolving so the light does not mask a future fault.
Engine Oil Level Sensor Circuit Range/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 oil level sensor is electrically intact, but the level reading is implausible — for example a constant value across drives, jumps that cannot match real oil consumption, or readings outside the design range. Often a contaminated or aged float/ultrasonic sender.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
