How do I remove the engine oil level sensor?

[AFournier]

Ok so I'm getting faulty oil level signals on the dash display. First thing I'd like to do is unplug and plug it back in. If I still get the message, I'll order part number 12639127. Problem now is that I don't know how to unplug this thing, or to remove it. I don't see any nuts or screws. Looks like a circlip. I've attached a picture that shows the sensor in question (hope that's the one). There is a red tab on top that slides back and forth. I'm guessing that sliding it out is the first step. Then I don't know what to do from here. Any tips appreciated!

 

Cheers,

Alex

You have to take the oil pan off to remove and install it.

 

That is how I understand it from looking at that part on GM's website.

Definitely have to remove pan. What you see is just a pass through connector for the sensor in the pan.

To unplug it pull the red locking tab back then compress the connector, you'll feel it move when you squeeze it.
