Default Low Oil Level Warning...

01 C5... DIC keeps telling me Low Oil Level..
Checked Oil multiple times and it was fine..
Replaced oil level sensor..
Cleared all faults with a tech II scanner..


Still keeps tripping this Low Oil Level Sensor..

The wires got "slightly" burnt on the exhaust manifolds at some point but I re-wrapped them in electrical tape.

Any ideas? Do I need to run new wires or does anybody know of any other reason this is happening?

Thanks for any advice!

My bet. Have you rung out the wires to see their condition?

Could simply be the sensor in the oil pan has gone bad.

I know you said you checked the oil level, but FWIW 01's have a known issue with the rings that causes them to use some oil especially when rpms are sustained above the 4K mark for any period of time. My 01 uses a little oil between every change and every once in a while (a few thousand miles after my last oil change) I get the low oil level message in the DIC.

When I finished building my new engine the oil level unit read low oil level. I replaced the unit and got the same low oil level alert. I found that one of the pins in the plug in was disconnected. Replace the pin and had the same problem, put a meter on the new sending unit and found the new unit was faulty. Put another unit in problem solved.

There is no way to tell you have a bad sensor from the factory until you install it.

Wow, I should have known you would chime in with such helpful and pertinent information.

I am not the know-all, be-all that you are so I took my car to someone else who diagnosed the issue with the low oil level warning. Do you think most techs that are performing this kind of work are testing every new electrical part right out of the box just in case?

With the exception of you, that is.

I did not say you were full of $hit, or wrong for that matter........just asking the question. Obviously, you do not like to be questioned, when you do not know the answer.

As I recall, I spent quite a bit of time, trying to assist you with a problem, when you could not find your ***, with both hands tied behind your back.........never again.

Finally, suggesting that I am a "know all / be all" is silly. I distance myself from topics in tech, in which I have no experience/expertise............you should do the same.

It is located on the side of the oil pan on the passengers side.

Would I be correct in assuming that the sensory is in the same location on a '99? This just happened to me this morning. DIC codes were for the TPMS (need to reprogram the sensors (I think that they got switched when I put on new tires in the spring)). Is there a way to check the oil level sensor?

I've been having the same issue & this will the third time to replace mine since I got my car in Aug of 2015. Is there a better aftermarket sensor than the AC Delco version?

Default C5 Oil level sensor vs. transmission cooling lines

Decided to change the oil level sensor on 2003 C5 / Automatic. Get low oil warning from time to time even with it topped up properly. Unlike the service manual pictures, the transmission cooling lines run right behind the sensor. Anyone had to deal with that when changing the part? Thanks.

You can also verify the level sensor circuit 150 . The sensor is closed when the oil level is OK . If bad connection appear in Splicepack SP122 or the ground point G105 appear it can increase the loop resistance similar to a open level switch " resistance ".
I would have inspect /clean these places and inspect the oil level connector before replacing the switch

Thanks, haven't replaced it yet. I am familiar with checking connections; a mouse decided to sharpen its teeth on a few wires between the engine and front composite leaf spring. :-(

I am doing this now, did you remove the lines or find a good way to do it? Special socket?
