Oil pressure switch filter/screen for 4.3L V6? I can't seem to find one, was there a screen on the V6?

Thumbnail Dorman Oil Pressure Switch 926-041  Yes there is a screen. 

 

Look from the passenger side just below the throttle body and to its left for a

It's under that plug and is screwed into the VLOM. 

 

Removing the air box first makes it easier to see and get at but not required.

I might be using the wrong search. Do you know part number by chance?

Not anymore. Tossed the package. Not an expensive part even at the dealership. Take you VIN and he will have that info. I'm pretty sure the all use the same screen.

After doing a complete dod afm delete on my 2016 Silverado 5.3 LT motor  I Periodically get a po6dd code saying oil pressure solinoid stuck close and from what I understand that puts it in low pressure mode, is there a way to get it into high pressure and leave it there?

I just did a 2016 4.3 for P06DD and what I found was the timing chain tensioner had broken and worn a hole in the oil pump right at the end of the solenoid.

bringing this back from the dead.

 

just completed a DOD delete AND oil pump replacement.  now getting a po6DA.  was getting a po6DD before this.  that's why I went ahead and did the oil pump replacement.   I don't have a check engine light but my mechanic is getting it on his diagnostics.  runs fine, oil pressure is 20-40 at idle depending on temp, and anywhere from 50-70 during driving and acceleration.  he can see the solenoid is working, he can turn it on and off with his device but sometimes it malfunctions.  

thought it might be a wiring issue but just wondering if anybody has had this before.

The dealership replaced my oil oump in Dec 2021, March 2024, and April 2024, and now the stupid lifters have failed a week after the last oil pump was put in.  But they can't tell me why the oil pumps keep failing.  Any ideas?

Yes.  The mechanic put the new solenoid in but didn’t plug it up. Had to pull the front plate off again and plug it up. After that it was fine.

Did you figure out what the problem was. I’m having same issue on my 2017 GMC 1500 denali with the 6.2

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!

      2026 Z71 Forward and Rear Park Assist help

      By Slow · Posted

      2026 Z71.  The other day I was backing a trailer into the barn.  The alarm was going off just because the trailer was in the field of the warning sensors when you get too close to something.  For some reason now the warning alarm doesn't work anymore.  It used to go off when I was just normally backing my truck into garage.  I still have the guidelines in the back up camera.  Is there a button or something to push to turn the sound/Alarm on and off?  I have the touch screen in this truck.  There isn't a "P" on the dash except for the parking brake.  I can't find anything in the touch screen under settings or vehicle.  Thank you in advance.

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      OCI, not when but why?

      By KARNUT · Posted

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.
