Ohio Jim Posted September 21, 2013 Report Share Posted September 21, 2013 Good evening All, Today, I was running late for work after helping my son change out the heater core on my daughter's Deville, I got the Low Oil Pressure, Shut off Engine information on the DIC. This happened to me once before, about a year ago. Both times I immeidately shut down the engine and coasted to a stop. I opened the hood and verified there was plenty of oil using the dip stick. I re-started the car and all has been fine. Should I be changing out a sensor, or what? Is the oil pressure sensor located at the top of the filter? I am putting together an order for Rock Auto, so I might as well change the sensor out at the same time, if that would be the culprit. It seems I replaced two "O" Rings that had been leaking above the oil filter once before, but not the sensor. Please advise your thoughts. Thanks Ohio Jim Link to comment Share on other sites More sharing options...

Should I be changing out a sensor....? Is the oil pressure sensor located at the top of the filter? Yes and yes. Caveat. Do not install a pressure sensor switch other than the OEM ACDelco part number. Generic aftermarket switches are not designed/calibrated properly for the oil pressures encountered in the Northstar engine. Jim Drive your car. Use your cell phone. CHOOSE ONE !

Ohio Jim Posted September 23, 2013 Author Report Share Posted September 23, 2013 Jim D, Thank you for the reply! It happened again today on the way to work! I will order the AC Delco unit from Rock Auto and put it to rest! Sinderely, Ohio Jim Link to comment Share on other sites More sharing options...
rockfangd Posted September 26, 2013 Report Share Posted September 26, 2013 I would recommend replacing the oil level sensor if you have not already done so also. Replacing both should give you a long time of oil peace GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
Ohio Jim Posted October 5, 2013 Author Report Share Posted October 5, 2013 rockfangd, Thanks for the additional interest. Where is the oil level sensor, and if you don't mind, what is the point of replacing it with the pressure sensor? Thanks, Ohio Jim Link to comment Share on other sites More sharing options...
rockfangd Posted October 5, 2013 Report Share Posted October 5, 2013 it is not far from the other sensor. Front side of the block between the subframe, right by the a/c compressor. They are fairly common to fail and show a false low oil level message. I figure if I am right there it is easy to do both GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
Ohio Jim Posted October 5, 2013 Author Report Share Posted October 5, 2013 rockfangd, Okay, I see Rock Auto has them for less than $30. Thanks for clarifying. Ohio Jim Link to comment Share on other sites More sharing options...
