P250E
Engine Oil Level Sensor Circuit Intermittent/Erratic
The oil level signal jumps or drops out intermittently — usually loose contacts, vibration cracks at the sender or oil sloshing on bumpy roads. The ECM filters short transients but flags the input when the noise pattern exceeds the diagnostic limits.
