Newbie from Minnesota "Oil pressure switch problems"

Hello folks.

I have a 2010 GMC Sierra with the 5.3. 

Last winter I got bent over to the tune of $450.00 to replace my oil pressure sensor. Well exactly a year later and we have to do it again. I want to relocate this sensor. I made a new wire harness to do this. I made it 42 inches long. At first I was going to put the sensor above the oil filter by using a aftermarket block that goes to the oil cooler. I have a oil cooler as a option on my truck so that`s out the door. I could use a fitting from the original location and run a hose out into the open? Or lastly install the sensor in the rear oil galley plug. I read that plug is a 16 mm x 1.5, the same as the oil pressure sending unit. Magic right? But nobody has done this from what  I can find on the internet. 

 

Advise?

 Thanks Joe

Have you replaced the lifter oil filter under the sensor? Pretty common to get plugged and people assume it is the oil pressure sensor.

Yes both were replace exactly one year ago. Oil changes at shorter intervals 2500 miles or every 3 months. I drive 22 Miles round trip to work each day and the truck gets to full operating temp.

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
