SOURCE: Audi 80 oil pressure light

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: fluctuation on the oil pressure gauge reading

The oil pressure sending unit is a sensor with an internal diaphragm, if the internal diaphragm is damaged , or the line to the diaphragm is blocked you can get this kind of fluctuation on the oil pressure gauge.

The oil pressure value must be read by installing a mechanical gauge near to the oil pressure switch and checking the pressure.

If pressure is ok, replace the sending unit. If there is a real pressure drop, check the oil pump.

If you still get fluctualtion after replacing the oil pressure sending unit, replace the oil pressure gauge.

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.

SOURCE: Porsche 944 S2 inaccurate petrol gauge reading and oil level warning light

This is not a known solution, but in general these cars suffer from voltage and current drops on electrical connections due to corrosion on contact surfaces. I cannot remember the number of times I have read about electrical problems on these cars, and the problem was usually solved by cleaning the electrical contacts or replacing a relay going bad (BTW, this car does use a lot of relays however I doubt there is one in the fuel gauge circuit).

Also, I have a spare gauge cluster for the 944 and when I look at it, there are some resistors on the "printed circuit" piece. If one of those were to lose tolerance, or burn open, it would no doubt have an effect on the accuracy of the circuit. I would check out that circuitry and test the resistor values as a last resort -- it is not likely the gauge itself if it is working at all. However, before doing that I would clean the electrical contacts thoroughly. I have not tried to gain access to the wiring harnesses for the gauge cluster while it is in the car, but I doubt it is possible. So, if you have exhausted all other ideas go to the Clark's Garage site for instructions on how to remove the dash, and just follow the portion that applies to removing the gauge cluster. Go to the local electronics hobbyist store, or online, and obtain a good contact cleaner and clean all of the electrical contacts while also looking for loose or broken wires. NOTE: Be careful and gentle dealing with the plastic connectors on these cars as they tend to be brittle and little tabs break off easily if man-handled. Go slow, be in the right frame of mind and use good lighting so that you can see what you are doing.

have oil pressure checked to see oil pump is faulty.make sure your oil is the right viscosity if too thick that will cause high pressure.if all is good.your pressure gauge is faulty.

I just performed a compression test on my PT Cruiser because when it died the Oil Pressure Lightindicating low pressure came on & has remained on & I was told to check the compression.


From what you are saying you have no compression on 2 cylinders . which means that the rings are broken or worn out or you have a head gasket blown on 2 pistons . . Head off sump off replace rings , Surface the head new head gasket , big work

What should the oil pressure be on the cars guage


around 10-15 psi at idle and around 40-50 psi at 2000 rpms viscosity of the oil in use and the oil temperature will have a variance on the pressures so if it is too low , the first thing to do is to up the viscosity of the oil in use
upper pressure is governed by the pressure relief valve in the pump or oil galley
check with a mechanical gauge it the gauge has an electronic sender as the sender may be reading low on the pressure gauge

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

Why is my Ford territory oil pressure light intermittently coming on


Good Day

Firstly check your all Oil pressure switches if they are not faulty.
Remove your electrical oil pressure switch and fit a mechanical oil pressure switch and start the motor:Oil Pressure reading should be between 4-8 bar on the gauge.
Motor must be at working temperature.
If Oil Pressure is below 4 bar their could be a problem on your crankshaft.Depending on milage.
Your Big end and Main bearings determine your oil pressure.
If the engine milage is high this can cause oil pressure fluctuation as their is wear on the bearings.

Martin

Low oil pressure reading


check that the oil level is not over the mark as this causes foaming of the oil and loss of pressure. At 80km/hr you will be doing around 3 grand and that will be enough to whip the excess oil into froth.. Too much oil is worse than too little oil.

a oil gauge reading maybe delayed until car starts and builds good oil press.Did you check for spark
was car running good before this happened? Do you have a rpm reading when cranking car?

What causes high oil pressure reading 1990 toyota pickup?


Probably a faulty oil pressure relief valve.

If not done already, you should have an independent oil pressure gauge hooked up to the lube system by a mechanic to check that the high oil pressure reading you are getting is correct. Before doing this change the engine oil and the oil filter and ensure you use the correct oil and only fit a quality and correct spec oil filter.

1994 Chevy silverado 6.5L turbo diesel: My oil pressure is between 40-60 for the first few miles on the road. then drops and seems to hold steady at around 40 while my foot is on the gas, then drops...


I'm not sure why you want to change the oil again. Your oil pressure numbers appear to be normal. Replace the oil cap if it's bad. You'll have to scan the ECM for codes to find out why the the check engine light comes on.
