2005 nissan armada oil gauge

To fix the oil gauge on your 2006 Nissan Armada LE, you may need to replace the oil pressure sensor. According to a post on the Nissan Armada & Infiniti QX56 Forums, a high oil pressure reading on the gauge could be due to a faulty sensor. You can try replacing the sensor by following these steps:

Remove the wire connected to the oil pressure sensor.
Unscrew the old sensor and remove it.
Install the new sensor and reconnect the wire.
If this does not solve the problem, you may need to replace the oil gauge in the dash .

As for the gas gauge, it could be due to a faulty fuel level sensor. According to It Still Runs, you can try replacing the fuel level sensor by following these steps:

Pry off the rubber gasket from around your fuel and temp gauges on your dash with a flat-head screwdriver.

Withdraw the gauges from the dash and disconnect the wires.
Rub a pencil eraser on both ends of the electrical connections to clean any corrosion from them.

Install a new fuel level sensor and reconnect the wires.
If this does not solve the problem, you may need to replace the gas gauge in the dash.

also note the are hose is subject to a recall so be sure this has been done...

Assuming the crankcase is full of oil, I doubt the cooler would cause a drop in pressure. Only a small percentage of oil flows thru the cooler.
It could be the pump or strainer, but could also be worn bearings.
The first thing you should do is have the pressure checked with a mechanical gauge to make sure your electric gauge is correct.

You may have a defective oil pressure sending unit on the engine or the oil pump relief spring may be sticking. Have the oil pressure tested with a special tool that goes in the oil port the sender is screwed into to determine the cause of the high pressure.;

• 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.

The gas you use shouldn't change after any miles. Keep it to what the factory recommends. You'll be wasting your money if you put premium and it only needs regular.

The guage may rise a little when you accelerate the vehicle...but if it is pegged high, and does not fluctuate, when you turn your ignition key on an off...Your oil pressure switch maybe going bad...Goodluck

NO.... BUT THEY COULD HAVE COMPROMISED THE WIRING OR SWITCH AT OIL FILTER AREA

Change the spark plugs and wires, air filter(K&N)click here to get one,
fuel filter, thermostat, pcv valve, and buy some marvel mystery oil at walmart..you can put it in your gas and oil..
