Your oil pressure sensor is not very expensive and is easy to change, I would start with that. If it does not cure your issue I would suggest hooking in a mechanical gauge to verify actual pressure and if it is not 80 psi I would look at changing out the factory gauge.
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
May be blockage in the system caused by either Dirt or heavy build up of carbon in system but more likely the filter is doing its job and his becoming blocked.
Change the oil when it is HOT and the filter and you should be OK
The oil sending unit is located on the engine block behind the drivers cylinder head area.You have to climb up on the motor to see it cause it is hard to see behind the wiring harness.You may also want to purchase a new sending unit because it is very long and you might need to buy the sending unit socket to replace it.Hope this helps.Good luck.
Your problem may have nothing to do with the sensor but in fact, the pressure relief in the pump may be stuck. Install a mechanical gauge on there temporarily and check the actual pressure. If normal then the gauge wire may be grounded somewhere. If it reads the same as the one on the dash then the relief is stuck (sometimes it can be freed up by draining the oil filter, filling it with marvel oil and re-starting, sometimes takes time though...otherwise you'll need to take care of the pump)
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.
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.
