Break in the wire, and there may be 2 sensors in the engine. also check all your fuses under the hood. DO NOT run it with out knowing if you do have presure

I would star by checking the wires and connections for these gages. If they are good then replace the gages.

SOURCE: oil pressure reading in 2003 gmc envoy

No problem with the oil pressure, the norm is between 40 to 60. Anything lower then 40 you have low oil pressure and anything above 60 then you have high oil pressure which is caused by a blockage in the system.
What is common is the oil pressure gage fluctuating for the first 200 miles if the oil pressure sending unit is getting worn. Good maintenance will keep the engine clean and running good but the oil pressure sending unit is inexpensive and easy to replace. Next time you do an oil change you can have them change the sending unit.
Good luck and hope this helps. You can pick up the sending unit at Auto Zone and most auto parts store and will have the step by step to replacing it. If you do attempt to replace it. make sure you DO NOT USE any Teflon tape or silicon on the threads, they are tapered and need a good ground to the engine for proper readings.

SOURCE: oil pressure gauge reads 80 while running

could be one of two things, oil pressure switch (located on top of engine behind intake) or instrument panel cluster, if your vehicle has under 70,000 miles, it's covered under warrenty

SOURCE: low oil pressure

You didn't mention the actual pressure but an engine requires as low as 6 psi when the engine is idling and 15 to 20 psi while driving at higway speeds. Your Yukon requires a 5w-30 weight oil. If the oil used is correct, you will want to have the pressure sending unit and gauge checked.
A mechanic will install a "mechanical" oil pressure gauge tester on the engine to find out what the actual oil pressure is. If the mechanical tester says the oil pressure is good, he will then begin to diagnose the electrical pressure gauge system.
If on the other hand, the mechanical gauge verifies the pressure is still low, he must diagnose the engine mechanical problem that is causing the low pressure issue.
Good luck.

Possible dsmsge from driving weeks with high oil pressure? btw 2004 GMC Yukon XL Denali


No damage will occur. Have you checked the oil pressure with a manual test gage? If not do that and please understand GM oil pressure gages are prone to reading high pressure when the sender is defective.

I have a 2003 GMC Sierra 1500 and my Oil gauge went to 80 Can't figure out what it is I think its a sensor But I'm not sure


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.

Where is oil sending unit located?


You're vehicle has two sensors for the oil,an oil pressure sensor switch & oil pressure sensor.If oil pressure gets below 6psi,the oil pressure sensor switch will turn a dash light on to let you know the pressure is at a dangerously low amount.So if you've got a dash light on,the pressure sensor switch needs to be replaced.Its located to the right of the oil filter housing,on a 2.0 liter.Its located to the left of the oil filter housing,on the 3.0 liter.
If your oil pressure gauge is reading inaccurately,you need to replace the oil pressure sensor instead.Its located near the ac compressor.

Oil pressure gauge reading zero


check the oil pressure first, it should read around 10 to 14 psi. If pressure is inside the range then your pressure sensor is bad. If lower or reads 0 psi your got a engine problem, further diagnosis needed. Good luck.

No oil pressure on my 2009 Yukon


You need to be careful here. If you are driving your Vehicle with ZERO PRESSURE, you are going to blow up your engine.

There is also one of 2 other scenero's for a GM Vehicle

FIRST: Instrument Cluster STEPPER MOTORS are KNOWN to be going BAD in GM's/. If the Stepper Motor is bad, make sure you replace it with a X27.168

SECOND. Your Sending Unit could have come unplugged or the Unit itself went bad.

I am Betting that your Stepper Motor went bad (Happens that Frequently).

I would put a Gauge on the Motor and see what the Oil Pressure Actually is, if it is Truly ZERO... do not start or Drive the vehicle and take it to a Good Mechanic or if still under warranty.. To the DEALER

Oil pressure gauge goes to 80 and stays


Another gauge needs to be connected to the car to check that oil pressure sensor or the gauge itself is not the problem.

If an independent gauge shows the same readings I would suspect a sticking oil pressure relief valve.

I have a 2006 chevy silverado 5.3L..When in idle oil pressure gauge goes to 80 and when i accelerate ail pressure goes to zero ...is it the oil sending unit?


It could be the sending unit. If the truck is low on oil it will cause something similar. Be sure the oil level is topped up. The only way to be sure it so measure the actual oil pressure at the engine with a proper gauge..

I replaced my oil preesure sensor and my gauge


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)

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.
