    the sensor in the pan is for oil level. you shouldnt have to ever see that light because you check your dipstick every so often, right?

    the sensor on the oil pump housing is for oil pressure. if that light ever comes on it's too late because it only comes on when it sees less than 5psi and that's way too low. expect a new bottom end if you're seeing this light.

    The OP and myself are talking about the low oil level light on the right side of the cluster. This is the sensor in the oil pan that determines if you are low on oil.. And I did check my dipstick and there is plenty of oil in there..

    I guess I should of just left the old sensor in there...

    I have a 97 Grand Prix with the exact same problem.. the oil level light sometimes comes on but never when I restart the engine again.. changing the sensor nor the connector helped.. Has anyone found the solution? Thanks

    Have the same problem with the 98, exact symptoms. Replaced the sensor and no change.

    Maybe next oil change do a Risolene engine flush before changing the oil. If this is somehow caused by a sludge build up condition it could help, either way wont hurt and it only puts you out about 5 bucks.

    No sludge on the 98, I only changed the sensor because I changed the pan and gasket.

    Changed the pan? Nice. Thats not as simple as it sounds.

    I have gone through 2 oil sending units since this original post. Seems to take care of the problem for a good while.

    Also the 20w-50 was just an experiment (mechanic had me come by and check oil pressure a few times to see what was going on). Next oil change went back to 10-30 and replaced sender the first time.

    I am having this exact same problem.

    My oil level notice in my 2007 would come on a few times a week at startup. I change the sensor and now it comes on everytime its cold. It doesn't do it when the engine is warm.

    The replacement was a brand new acdelco unit. Any suggestions on how to clean the connector to the sensor? It's the only thing I can think that might help.

    Just to update this as my case was resolved 100%.

    Apparently I hit something dead center on the oil pan. This damaged the oil pickup.

    The pressure was verified with a mechanical guage. Low after 3,000 miles on castrol 10-30 synthetic high mileage. Normal after oil change with the same stuff.

    Damaged pick up caused the top oil in the pan to immediately go back into the engine. Wearing out the oil much faster than normal. Thus causing the low pressure.

    So, by looking at my earlier post as a start date, I drove it 60,000 miles like that. Then traded it in.

    Are you saying the low oil sensor has anothing to do with the oil level in your case, and just was just based on low pressure?

    No. I had the red low oil pressure light.

    The low oil level sensor was surprisingly accurate.
