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.

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: my 01 bonneville oil pressure gauge is showing 120

HI, the oil pressure sending unit may be malfunctioning at this point. this will cause erratic readings. if your oil level is proper and there are no apparent oil leaks, you will need to replace the oil pressure sending unit. this will fix the erratic oil pressure readings.

Concerning the gas gauge. this device also has a sending unit that sends the correct fuel level reading to the gas gauge via wire transfer. this sending unit is located and attached to the fuel pump assembly inside the gas tank. replacing this device will fix this issue as well.

Please rate and god bless:)

I have a 2004 Nissan Titan with 98,500. Yesterday my oil pressure gauge started staying on high all the time while the truck is on. When i turn it off then the gauge drops all the way.


Replace oil pressure sending unit. Sender is located on the engine block close to the oil filter. Usually has one wire connected to it.

My oil pressure just jumped to the max reading on the gauge. can this hurt my motor if it is really high oil pressure.


Does the oil pressure go to max or some where in between when you turn on the key without starting? This is what happen to me it was the oil sensor down by the oil filter. The cost for the sensor is about $100.00.

My 2005 Nissan Armada is reading oil pressure abnormally high. The gauge is maxed out.


  • Well it could be a bad oil pump or a bad Oil Sending Unit. If you have an oil pressure gauge you can pull the sending unit and stick the pressure gauge in there and see what the reading is. I would thing 60PSI would be suitable.
  • I believe this Oil Sending Unit is on the front (possibly the back) of the oil pan.
  • Just remove the connector and put a wrench (or a deep socket) and twist it out and replace with a new one.
  • Make sure the oil filter is snug and not leaking as well.
  • Check your oil level too and make sure it is properly filled.
  • Good luck and thank you for using FixYa.

1984 nissan 300zx oils pressure gauge goes to


Sounds like an electrical problem, make sure the ground leads to the engine are good and the battery terminals are clean. It might just be a bad connection in the wiring harness try jiggling the connections to see if it makes the gauges jump when it is running.

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 on a 2004 5.3 liter silverado at idle is around 20


The pressure to be most concerned with is the reading in gear at idle with engine warmed up...Low end really should not be below 20. If pressure wanders, change the sending unit and check actual pressure with a mechanical gauge if necessary. The age and quality of your oil, as well as temperature all play a part in pressure, as well as internal wear from time & miles of use. If pressure changes with rpm, that is normal. 40psi is good while driving.
need more info just ask.
