oil level sensor - failed?

[Roger_850T]

I received a "Low Oil Level" message in the DIM. Continuously. At next oil change, I pulled the sensor and cleaned it, and put it back. Error message remains.

Researched, and it seems that occasionally these sensors fail, and they are not fixable. So, I ordered up another sensor (at $200). Oil change time, replaced the sensor - error message still came back.

I checked the wiring, and I have +5V and ground like I should, and the signal line also floats up to 5V with no sensor attached. Signal line has 230 ohm resistance to ground, so I'm guessing it's got a pullup resistor on it. Cleaned all the connections, made sure everything was seated nice and tight, and the error still remains. (The actual oil level is fine through all of this.)

Now I'm wondering if the "new in the blue box" sensor was bad, or if there is something else going on.

I tried to see what the ECU was reading, but I couldn't find it. I found every other parameter that VIDA/DiCE has, but this one is missing. The help screen says I should see a value between 0% and 100%, with ~23% to 83% being acceptable values, but I don't even see the parameter.

Before I just throw out another $200 on "it must be a bad sensor", does anyone have any other suggestions?

Thanks in advance!

Following up on this, I seem to have this issue fixed.

The sensor is very sensitive. It will indicate yellow when the dipstick is in the middle of the range, and red when the dipstick is towards the low end of the range.

I seem to have fixed by adding oil until the level was right at the very top of the dipstick range and keeping it there.

Oil change today, keeping fingers crossed that I can duplicate this success!
