Posted: Sat Dec 17, 2011 8:42 pm Post subject: Oil Level Low message, But Its Not Low
Oil pan gasket was leaking so I dropped the oil pan, installed new gasket and put it back up. Cool, no leaks. But now I have an error that says oil level low when I start the car. After a min. it goes away. The oil level is not low. I replaced the oil level sensor with a new one. Still, shows up at start, stays on and then goes away. So if it stayed on, then I do have low oil level right? Any ideas what is telling the car the oil level is low when its not with a new sensor?

For about three years I had my brake fluid sensor unplugged because I had the same issue. It wasn't until recently when I've had time and money to actually fix it. Turns out is the master brake cylinder was bad the whole time even though I had no problems braking. Something about a back or slave cylinder in the master not working is what was setting off the error.
Google again has thwarted me with trying to find other peoples solutions. So if anyone has a good link/fix please share the link!!
Hum.. Good idea. I thought that would fix the original sensor when I had to remove my alternator for the coupler removal but it didn't. But I'd be willing to try. But here is an update. Today, it hasn't gone off yet. Yesterday it went off I think two of the five starts I had...
Left the battery disconnected for two weeks. Same issue.
Any one have any ideas on what can cause this?
If you had the pan off, and you have replaced the sensor in the oil Pan. You are sure the sensor is in correct and you're sure it is not the sensor. ( you can check the old sensor by lifting and lowering in a cup of oil while checking with an ohmn meter.
Next step to check is the wire.
check the sensor wire for cracks or breaks in the insulation on the wire and/ or connector end that plugs into the sensor.
Also check the wire that it did not get pinched between up between an engine or frame component. check that the wire was not stretched and might have a small break inside.
Wire looks good. Whats getting me is that I will go days without seeing this error.. But when I park randomly at a spot that has a little incline or decline, it will turn on, I'll drive off and then it will go off and not turn on until I park at another decline/incline. I don't get it, wrong gasket? I'll double check the sensor part number but they looked very similar. Obviously they are in the same level in the oil pan. Oil level is still perfect.
Went to the dealer and they pointed out that everything is good except that the oil sensor isn't getting oil. So it and everything else is good and correct. They showed me a expanded view and Windsor tray? <-- not the right name but the tray in front of the sensor is not allowing the sensor to read the correct oil level. So back to the place that dropped my oil pan..
