When driving, all my gauges, except the battery, go all the way to the left...
When driving tachometer does not move and oil pressure gauge does not reset 2005 chevy tahoe 2005 Chevy tahoe....while driving, all the gauges, except the battery, goes all the way to the left. Also, the car icon with the lock comes on too. They just all go back and forth. Sometimes all together and sometimes separately.
Re: When driving, all my gauges, except the battery, go...
This model always this problem, usually after about 90,000 miles and the other instruments will eventually follow. There are companies that will repair this for you just use google (instrumentclusters.com) to find them. I was charged 185.00 for the repair... GM wanted over 500.00!
a 6ya expert can help you resolve that issue over the phone in a minute or two.

The computing system on your vehicle has no safe mode for running low on oil . The only thing that will happen is the check gauges light will come on.
The oil pressure gauge is an analog device that is located in the IPC. The oil pressure gauge is operated directly by the oil pressure sensor circuit. As the engine oil pressure changes, the resistance of the sensor and the current flow in the oil pressure gauge changes. The current flow in the oil pressure gauge causes the needle to move in order to appropriately display the engine oil pressure. A sensor resistance of 1ohms will display as 0 kPa (0 PSI) and a resistance of 88 ohms will display as 80 kPa (80 PSI ). The IPC also monitors the oil pressure sensor circuit and interprets the current flow in this circuit in order to determine when the engine oil pressure is too low. If the oil pressure is too low, the check gauges tell tale will turn on. The oil pressure sender is located on the left side of the 2.2L. The 4.3L engine, oil pressure sender is located at the top left side, near the distributor/high voltage switch.
Try disconnecting the battery cables an hold them together for ten minutes , reset ECM !
Factory gauges (especially Fords) are not known for being terribly accurate or reliable. As long as the gauge is pointed in the "normal" range, I wouldn't be too concerned.
If you want to pursue it, remove the oil pressure sending unit and perform an oil pressure test with a mechanical gauge. If the mechanical gauge fluctuates the same way, suspect a worn or failing oil pump. If the gauge is stable, I would suspect a faulty oil pressure sending unit.
If the truck has high miles, consider moving up to higher viscosity oil or adding an oil stabilizer. If could just be that the oil is breaking down when it's hot and the engine can hold consistent pressure with the thinning oil.
have a mechanic test the oil pressure with a mechanical gauge
it is more than likely that the electric sender unit has failed and is sticking internally
the tic noise could be a relay working from an intermittent power supply or bad ground
Check fuse No. 9 (10A) in the driver's side kick panel fuse box. But if your other gauges are working (speedometer, tachometer, low oil light, etc.) then it is possible that when you jumped the battery you inadvertently reversed the cables and created a reverse voltage. This will impact some of the vehicle electronics. If you feel this might be the case, you should test the cooling system temperature sender to see if it failed. If it did, you should suspect that the fuel gauge drive circuit located in the instrument cluster is also failed.
Oil pressure can be checked at the sending unit passage with an externally mounted mechanical oil pressure gauge. To get accurate results from the test, make sure you follow the manufacturer's recommendations and compare your findings to specifications. Testing the Oil Pressure Gauge
Test the gauge by grounding the wire that leads to the sending unit on the block.
When the wire is disconnected from the sending unit with the key switch on, the needle on the oil pressure gauge should be either all the way high or all the way low. Grounding the wire should make the needle move to the opposite side of the gauge from where it was before the wire was grounded. If the vehicle is equipped with an oil pressure light, touching the wire to ground and then removing the wire from ground should turn the light on and off.
If either happens, the gauge and wiring are good and the sending unit is at fault.
Testing Oil Pressure
Pressure can be tested by temporarily installing an oil pressure gauge in place of the sending unit. Before testing, look up the oil pressure specifications for your vehicle in the appropriate service manual.
Bring the engine up to operating temperature.
Now shut the engine off.
Locate the oil pressure sending unit; usually it is on the lower side of the engine block.
Disconnect the wire from the sending unit and use an open ended wrench to remove the sender. Using pliers can damage the unit.

Tighten the oil pressure test gauge into the hole in the block where the sender was removed.

Check the engine's oil level and fill, if required.
Be extremely careful when working near a running engine. Always wear safety goggles or glasses with side shields when working around moving machinery and be sure that your clothing is not loose.
Now turn the engine on and check the oil pressure on the gauge.
Watch as the engine warms to note any excessive drops due to temperature.
Make sure the engine speed is set to specifications for testing pressure.
If necessary, us a tachometer and adjust the engine idle speed.
Record the measured oil pressure, then turn off the engine.
Compare the test results with the manufacturer's specifications.
If the oil pressure is within specifications, this shows that the oil pressure sending unit may not be working correctly.
In many cases, replacing the oil sending unit will correct the problem.
After the test is complete, reinstall the oil pressure sending unit, start the engine, and confirm there are no leaks.
