Engine Oil Level Sensor Circuit Range/Performance
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.
Affected components
- Oil level sensor
Common causes
- High likelihood: Aged or contaminated sender
- Medium likelihood: Foaming oil under high RPM masking the level
- Low likelihood: Sensor element aged beyond calibration window
