SOURCE: When I start my vehicle, Mmy oil pressure gauge

You oil pressure is read by an oil pressure sending unit, that sends information to your gauge. If the sending unit is bad, you can get weird readings. You can either replace it, or have a mechanical gauge hooked up to see the actual pressure.

SOURCE: Low engine oil pressure on

in order to check the oil pressure, you have to remove the oil sending unit, then screw in the adapter of the oil pressure gage, and then remove the start relay or fuel pump relay from the fuse and relay box, under the hood on the drivers side, and then crank the engine over 3-4 turns, and then record the oil pressure, and then disconnect the oil pressure gage, and then re install the oil sending unit, replace the start relay or fuel pump relay, and then start up the car, and check the oil sending unit , to make sure it is not leaking, if your oil pressure checks out within the specs, then you are fine, if it gives you a low reading, then you could have a bad oil sending unit , or a oil pump going bad on you. i would replace the sending unit first, then see what the gage shows.

Not getting oil pressure when turned on runs rough, oil pressure gauge is pegged high on 99Bonneville SE


I suspect the gauge/sender/ or wiring is bad. Does the gauge peg with the key on, but engine not running? An engine wont run long(maybe 10 min with no oil pressure). suspect gauge has nothing to do with a rough running.

Has 358000 miles, just had leaks repaired. Twice since my oil pressure gauge reads no pressure but not all the time? Why


1. Oil Pressure Gauge Not Working You will notice this happens when your oil pressure gauge is not reading, whether the engine is turned off, idle or running. Try to step on the gas to rev up the engine. If the oil pressure gauge still doesn't change its reading, your gauge is busted. It's best to replace it as soon as possible because you won't have any idea if your car is already overheating or not.
2. Oil Pressure Gauge Reading Too Low When your engine is idle, the oil pressure gauge will have a low reading. When the engine starts running or when you're already cruising or on the freeway, your gauge's reading should have increased. If it stays on a low reading, then you now your oil pressure gauge is broken.
3. Oil Pressure Gauge Reading Too High Another common oil pressure gauge problem is when your oil pressure gauge is reading too high when your engine is idle or when it's turned off. Rep

Oil pressure


Remove the oil sender unit and fit a pressure gauge , start the engine and check pressure, seems odd the oil light and pressure gauge both showed a fault at the same time, perhaps the oil pump relief valve stuck open for a short time.

Engine runs fine oil checks out good yet oil light comes on?


You need to verify that oil pressure is ok.
They sell gauge at the parts store which has to be connected to the engine block via oil pressure sender hole.
For that , take out oil pressure sender(unscrew) and screw the gauge in to the hole (con thread).Run the engine and see if pressure is ok at idle and on higher RPM.Gauge suppose to have scale (norm. , low , high ).If oil pressure within specs , repl. oil pressure sender.
Or just replace oil pressure sender and see if that helps.They are not expensive ~ $30.00 , gauge probably the same money.

Low oil pressure 93 GMC P/U w/350 motor w/205,000 miles gauge


While engine is running, open the cover where you add oil to engine and see if you see a good flow of oil, if good flow, could be as easy as replacing oil sending sensor. got to realize that if poor maintenance history your engine may not be building enough pressure at iddle to move your hydraulic operated valves, only when you rev it up it will pump enough to run smooth. if running engine too long, you may cause more damage to other engine components such as crankshaft and cam shaft bearings. if you can spare a few bucks, have a good mechanic check your oil pressure with a mechanical gauge. another cheap option is to replace oil pump. last resort if you love your truck as much as we do,replace engine or rebuild it. At 205,000 this is a normal symptom, other than timing chain problems, most engines don't make it that far. hope this helps!

Oil pressure loss


the 1st thing u do is have the oil pressure tested with a test mechanical gauge by a shop, most times it is just the oil pressure sending unit is defective, but never assume that is the problem, low oil pressure will distroy a $5000.00 engine very quickly, u can just try a new sending unit, but highly recommend a pressure test with a mechanical gauge before you run the engine anymore.

Oil pressure gauge reads 80 psi with engine off and pegs running


That is probably a defective oil pressure gauge or a broken oil pressure sender, it reads 80 psi just because that is the maximum value allowed.

Pressure can be verified by reading it with a gauge tool.
If you really have pressure over 70 psi when engine is running then start replacing the oil filter, and check that the oil lines from pump are not obstructed, if there is nothing in there then replace oil pump.

If instead the gauge reads 80 with engine off, that is a defective pressure gauge.

Oil pressure gauge suddenly reads maximum


Are you referring to the oil pressure gauge on the dash? If so, that is most likely the oil pressure sending unit having gone bad. The sensor runs about $40 - 50 (at least the last time I had to replace one on that engine). They are not terribly difficult to replace and I believe its a three wire sensor located back side of the engine, on the passenger side area. Its in a kind of tight spot and takes a bit to get it completely screwed out, but it can be done.

When they go bad, they typically will cause the gauge on the dash to read maximum oil pressure. You should be okay to run like that until you can get a new sensor as long as it is reading maximum oil pressure on the gauge and not low or no oil pressure on the gauge.
