Low Oil Pressure Fault Issue..... : Vortec 5300 5.3L V8

09 suburban oil pressure sensor

My truck is also a 2009 5. Pull that nut off, and then we can pull the wire out. I still get the lifter noise on start-up and I've been noticing that I am about a quart of oil low every few weeks. That is actually part of this fuse block. Issue went away for a week and came back. I fished it out using a pick with a curved end. It has shut off once or twice.

I was having symptoms consistent with others on my 2010 Silverado 5. Anyway, there is a service bulletin for these engines that have fluctuating oil pressure that requires a kit be installed. Start the engine and check for oil pressure. I had the same symptons on my 2009 Sierra, but they did not come and go, they just went. They do it all the time. We actually sell a kit similar to this at 1aauto. I checked the oil, and since it wasn't making any sounds like it had no oil pressure, just drove it a short distance home.

Now, pull up on the intake. Once those are loose, you can take this right here. Okay, the oil pressure sensor is on the back here. Tells me something is clogged with a bad oil pressure sensor. Check the voltage to the gauge it should be a steady 12-13. On these engines, the oil pump is mounted on the front of the engine and is driven off the crankshaft at twice the speed of a camshaft driven pump. I just bought an oil pressure test kit from Harbor Freight and my luck it didn't come with the right size fitting that will screw into where the sending unit mounts.

I assumed it was a gas cap and never had it checked. Okay, we'll reinstall this vacuum hose that goes to the brake booster. I flush engine and change engine oil and install new Bosch oil filter then I changed out the oil pressure switch and looked at the screen underneath the sensor and it didn't look bad but cleaned it anyway. Hopefully, that's it, if not the next part will be that damn oring. I took these all off to separate the rails and replaced them. The only time I had issues is when I let a friend borrow it and they put the Walmart oil in it. I have considered that it is possible that the Valve Lifter Oil Filter may be clogged or dirty and that one of the lifters may be sticking.

It's tough but you can just barely fit your hand back there. I mean, you can if you want to, but they will stay with it. Just make sure they're completely loose. In this vehicle, as you can see, there is no relay there where the fuel pump relay should be, and then the fuse should be right there. Check engine light is back on.

At this point, we're going to remove this cover, just lift up, and then just wiggle it forward. I have been driving it primarily on long trips 1K roundtrip each month. Okay, we're going to disconnect the connector for the throttle body. Priming the system can often be achieved by first disabling and preventing the engine from starting. I'm just going to slide it right back on the fuel injector, and then push down on the lock, and then do this for all the rest of them.

Low Oil Pressure Message: Locating the Mystery Filter

However, after driving back the 2 miles the problem recurred. My husband the mechanic by trade too has done almost everything but the oil pressure test kit or doing it manually?. If you don't have one, you can actually use a one and one-sixteenth socket, a deep socket, or a 27-millimeter socket will work as well, and then we'll use our ratchet. Remember, it's plastic so don't overtighten it. It's not impossible to do with the intake on, but it is a struggle.

I have had similar issues where rather suddenly I would be running at about 22-25psi oil pressure at 70mph. You can use a socket or a regular wrench. Now we are at home and we checked the oil level again and it took another Qt at that time. Remove the line with a 17mm wrench. Then we'll snug this up. To release the fuel pressure, there normally is a cap right here.

Has the technology reached a level that vehicles can be driven for extended oil drain intervals and remain free of contaminants, or is this marketing strategy to sell vehicles by promoting lower maintenance cost? When i installed the leveling kit on my truck, the truck had a really great stance with the front and back leveled. And that was at 187k on the engine. As I drove the next 150 miles getting home the oil pressure would fluctuate. Now, I'll release the connector. At first I thought there was an issue with the oil, as, after a full oil change including filter would put everything back to normal.

Truck has 110,000 miles, and it sounds like all are going to do this. In your case its back to the pump for me because of what you said abut the guage. At one point, this gauge was reading 80. Get a new gasket set and this will make your engine run better too with 100k miles on it. .
