I assume that you are talking about the sensor that reads pressure for you. The easiest way for me to find it is to crawl under the vehicle. It should be on the passenger, rear side of the engine, usually a few inches above the half shaft. I think mine was a 2 or 3 wire connection. Then I just used a cresent wrench to take mine out, and had the next one ready to go in so I didn't spill to much oil(mine always fail shortly after doing a fresh oil change).

SOURCE: reset button on an 04 buick lesabre

You can disconnect the battery cables for a couple minutes which typically resets the ECM to some predetermined (default) settings which may make your vehicle run or respond slightly different than it currently does but as you drive the vehicle it will relearn and adjust as needed. If you prefer to wait awhile then it will turn off itself after several --several cycles of the ignition ;so long as the problem is fixed or no longer exists and there are no other problems.

I had asked about the check oil light coming on and going off on my 2004 buick lesabre, the person mentioned a sensor in the oil pan. Can this be checked out by finding a dianostic code or does the oil pan...


I know nothing of a sensor in the oil pan. What you need to check is the oil pressure sending unit. The unit will look like this. 2c49e3a.png
Check the connection at the sensor to make sure it is secure before replacing. If you find it is leaking it for sure needs replacing. The unit will be located in a location like this on which is a 1995 Buick. 2a08cb5.png

1995 buick lesabre limited, oil gauge issue


Could be two things, your oil pump pick tube is clog, oil pan would have to be drop to check, or your camshaft bearing worn causing low oil pressure,I would not say piston rod bearing or main bearing, cause there's no knock noise. You will have better oil pressure when cold due to oil much thicker. so I would forget about a bad oil pump.
