Question about 2005 Buick LeSabre
I have 05 lasebre and the oil sensor light comes on and when I check the oil level it is fine. The cars temp is fine, not overheating at all. Is this just a bad sensor? Where is the sensor located?
This is probably an oil pressure sensor problem. Randomly going from 0 to over 130 is means the sensor is putting out out of range signals. Mine would even read --- at times. I told the mechanic to not spend any time troubleshooting just change the sensor. $121 including parts, labor and tax. The gage should read about 70 psi plus or minus several psi, and move up a PSI or two as you rev up the engine. It took him about 10 minutes to change it, once he got the part. There would have been a diagnostic charge of about $50, had I not been sure.

The oil sensor is a screwed in plug on the left side of the engine, and facing the front of the vehicle. I bought one here at eBay:
or at this eBay store: http://stores.ebay.com/AllDayParts-Outlet?_trksid=p2047675.l2563
Drain the oil from the pan, disconnect the sensor connector, unscrew the sensor with a wrench, remove the old sensor, install the new sensor (don't forget the "O" ring), and tighten it carefully (the nut is plastic), reconnect the connector, and pour the oil back into the engine through the black cap on the valve cover (near the yellow dipstick handle). Confirm that the oil level is correct.
