Check Oil Level


Paul S

Recommended Posts

I am getting this message on my '99 STS and the dipstick tells me the level is at max. Could this be the sensor located on the housing where the oil filter attaches or should I look eswhere? I haven't found anything in factory shop manual as of yet that refers to this display.

The sensor where the oil filter attaches is the oil pressure sender. The sensor that causes the CHECK OIL LEVEL to b displayed threads into the oil pan. It has a large hex (maybe 1-1/4" in diameter) and has the electrical connection in the center of the hex.

Just for the hell of it, while you're in there, you might want to check the torque of the oil filter adapter bolts, and maybe even switch up the "O-Rings" in there too. I did that and it solved an oil drip as well...can't remember the part# tho, maybe someone else does
