Hi Forum. My name is john and I bought a Prius Prime 2021 and start getting this message.. Low oil Level. The engine oil level is low. Add engine oil as necessary. If you require assistance, please contact Toyota dealer. Did anybody know which sensor can cause this message to come up? Where is the sensor located? Is any way to get this this notification to not come up?
2021 Toyota Prius Prime Engine Oil Level Sensor - 8949128091 - Genuine Toyota Part Low on the engine, just above the oil pan; you can click the diagram from the link above. A popular method is to add the right amount of engine oil so that the level is not low. Besides getting the notification not to come up, this will also postpone destruction of the engine, and that's why this method remains popular year in and year out. The owners' manual will show the kind of engine oil needed and the proper way to check and add it.
The recommended grade of oil is also stamped on the oil fill cap on top of the engine. It's likely 0W-16. There's a dipstick that can verify if your oil is actually low. Sometimes the light will come on in a turn because the oil sloshes around, and then goes out when you straighten out. Best to fill it to the middle of the two dots on the dipstick.
For some high-end cars, the engine is more delicate, and the lubrication requirements for engine lubricating oil are higher. If the engine lubricating oil exceeds the maintenance period, the engine oil alarm light will also be on. After the owner completes the maintenance, the 4S store will delete the engine oil alarm light, and the vehicle instrument panel will return to normal.
That's what I'm hoping too, and I read the original post four or five times over hoping I'd simply missed that part.
A two-year-old Prius/Prius Prime should neither consume oil nor have such a malfunction. Has the oil ever been changed in this car?
How come when a warning message or code comes up, there's this seemingly too often mentality in this forum to blame the sensor?
Regardless, regular oil checks are still required. From 2021 Prime Owners Manual, pg 603: ... and pg 602:
Of course, never assume that the oil level is OK without actually seeing the oil level on the dipstick!
