    Where do i purchase one? I've been to many auto parts stores and the aftermarket one's don't fit. They seem to just slide in place of where you connect them into. They say theres adapters or connectors so they'll fit?

    the problem is most likely the oil pressure sending unit, there is a TSB about this false high reading, replace the sender.

i think from memory that the oil pressure switch is at the back of the cylinder head, if its not there it will be located just above the oil filter, these switches are very cheep to buy and can be bought from any good motor factors. You are right to suspect the switch, its the first thing to eliminate before bogging your self down with more complicated and expensive problems.

SOURCE: 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.

Might be that the oil pressure switch is going out. Unless this has been happening for a while now.

SOURCE: High oil pressure reading

Hi, this is a oil pressure sensor malfunction. the gauge is getting a distorted reading from the sensor. replacing the gauge will fix this issue. also, check the fuse box for blown fuses.

if it is electrical oil pressure sensor I would start there. The best way to see if you have a major problem is to use a mechanical oil pressure tester. Take off the oil pressure sensor and put the mechanical tester on. The tester should come with a Gage. If it comes within your trucks oil pressure range than all is fine and replace the sending unit and see if that don't help your problem.If the tester runs high then the oil pump is bad or your cam-bearings could be the problem. But with cam-bearings you would usually get a low reading.

Oil pressure reads under the half way point and I know it had the right amount of oil,when you sit there in idle it don't read as high as it does when you are driving it?? Also does a 1997 has a key...

oil pressure gauges don't always tell you exactly what your oil pressure is (depending on the type of gauge) oil pressure is always higher when driving than when idling, as for the key you may have to check with your G M C dealer to find out if it has a chip in it or just get another key cut to see if it works,if your original key has a chip in it you will have to get another one from the G M C dealer.....hope this helps......cheers.

Oil pressure is still reading high even though I just changed the filter and oil.

A high oil pressure reading is a good thing, low oil pressure is something to worry about. Normally with a cold start, your oil pressure will remain high until the engine has reached operating temperature, then drop a bit, but again, high oil pressure readings are a good sign of a healthy engine. One other factor to consider is the viscosity of your oil, if your engine uses 5w30 and you switch it to a higher viscosity such as 10w40, you may also see higher oil pressure readings, so be sure you are using the correct oil for your vehicle. I hope this has helped you! :)

1986 ford thunderbird oil gauge on and beeping

I would check that the engine oil level is high, then I would check that the pressure is high enough by plugging a gauge into the oil pressure switch socket after removing the oil pressure switch.

There is a possibility that the oil pressure switch is bad, or the oil pump has failed, unfortunately.

I have a 1994 Buick Lesabre that suddenly devoloped a knock/ticking sound when the oil pressure gauge reads <40. If I hold the revs up till pressure goes >40 the knocking/ticking dies a little but...

sounds like you are getting low oil pressure, could be a plugged filter or plugged oil sump pick up, filter is easy oil pump required removal of the oil pan

Need to know what the proper oil pressure when idling and driving for 1994 jeep grand cherokee 6 cylinder 4.0 lt

the pressure will vary, You'll be approx 20 psi at an idle and 45 psi @ 2500 rpm's. If the car has a lot of miles, you can expect slightly different readings. As long as your reading, I would not worry about it. Also when the engine is cold, you'll always have a higher reading until the temp rises to normal.

Oil pressure seems to go to high while driving then when car is stopped it will read around 3/4.

The oil pressure will not always stay steady.When the oil gets hot it will read lower and higher with the RPM's.Pressures will read higher when you first start the engine then drop the hotter it gets.If it has not always been this way you may have a oil pressure sending unit going bad.

The tranny dip stick is behind the eng. on the passenger side between the firewall and motor.Its not easy to spot because it sits down in a little bit and is black in color.Add oil where you pull the dip stick out and not to much oil at a time.You will need to get a small funnel that will fit into the tube.Once you have found the it,check the oil level with the eng.running and hot to get the correct reading.Add a little at a time being sure you dont overfill.Recheck the level after driving and add more if nessesary.Hope this helps.

Oil pressure gauage reading high

depending on the weather, and how cold it is, oil pressure will run high until it warms up. now if it still runs high after it warms up then its most likely the oil sending unit.
