That warning means the vehicle’s oil level is either too low or the engine control module is receiving a signal that suggests it might be. In either case, it’s not a suggestion — it’s a serious warning you shouldn’t ignore.
Here are the most common causes behind this message:
- Low engine oil level: The most obvious cause. If the oil level is below minimum, top it up immediately with the correct oil spec for your engine.
- Oil level sensor fault: A faulty or dirty oil level sensor (mounted in the oil pan) can send false signals to the ECU, triggering the message even if oil level is fine.
- Wiring/connectivity issues: Damaged or corroded wiring to the oil level sensor can also create false alerts.
- Oil leaks: If your engine is slowly losing oil through external leaks or internal burning, you’ll keep seeing this warning no matter how many times you top off.
- Oil pressure issues: In some cases, this message is tied to low oil pressure, not just level — meaning a bad oil pump or clogged oil pickup could be to blame.
Luckily, the repair manual will contain everything you need to properly diagnose this issue, including detailed wiring diagrams, sensor locations, troubleshooting steps, and factory oil specs. It’ll walk you through testing sensors and circuits, identifying leaks, and how to replace the oil level sensor if necessary.
Bottom line: don’t ignore this warning. Low or unmonitored oil can quickly lead to catastrophic engine damage.
