Stupid "Low Light"

1999 Olds Intrigue, 3.8 eng.Last month, I replaced the Oil Level sensor while changing the oil, which was causing an oil leak due to a broke seal. Three weeks later, the "Low Oil" light came on and stayed on shortly after starting the car. I checked the oil level and it was full. I went ahead and drove it to work. No engine operating errors during the drive. While continuing to drive the car (yes, driving it), I did notice that the light stays off after starting the engine at operating temps, but comes on while the engine is cool (Faulty sensor?) I asked an Autozone associate about a Oil Pressure gauge to test the engine but was told that they dont sell such a thing. Chiltons repair manual says to use a 3amp fuse jumper to test the Oil Level and Oil Pressure sensor. I have no idea what a fuse jumper is.

Re: Stupid "Low Light"

To test oil pressure, you remove the oil pressure sensor and attach an oil pressure gage(guy at Autozone does not know what he is talking about).....

Chiltons is half right....you use a fused jumper lead(all this is, is a jumper wire with a fuse holder in series) to test the oil level sensor......stick a 3amps fuse in the fuse holder, disconnect the harness to the oil level sender, and attach the fuse holder to the two wire harness.....your oil level light should now be off, whether the engine is cold or hot, it should be off....if it stays off, bad sensor......if it comes on, the wiring circuit is bad, or the cluster is bad(I think the wiring goes directly to the cluster)......

Sensor passed the test, now I cant seem to find a part store that has it or can order it. Does anyone know the part number for the Oil Level sensor wire harness?

Finally got it. Replaced the pigtail with new one. However, the "Low Oil" light still came on. I don't know where to go from here.

Re: Stupid "Low Light"

I say if you have done everything possible

just ignore it its a very important light and worth trying to have a shop diagnose

but if to broke for shop constantly check level 2 or 3 times a week

and maybe evan after your trips that's about all that seems to be left

fix it or check it constantly the temp gauge will kinda help olds in the summer
often ride towards the middle on temp more than that might want to check

the best one though is find a good shop or dealer and get ti fixed
