SOURCE: Fuel and oil pressure gauge

hello this sounds like a bad ground to the gauge cluster first thing to try with the key in the on position tap at gauge area see is there any change if not open dash area were gauges are wiggle to see if they are grounded good into dash grab a test light take end put to the ground on one off the gauges touch other power wire with probe while key is in the on position same for both gauges if no difference reinstall you need to check grounds on both gauges by tracing wires it might be easier if you locate your oil sending unit take the wire off attach alligator clip to wire now touch positive side of batterey if it lights grounds okay trace back to units oilsender,sending unit at gas tank goodluck please rate

Buick with a 5.0?? OK, regardless, pressure should not drop like that. Possible that fuel filter is full of **** & should be changed, or, you may indeed have a bad pump... (can happen). Sending unit: sounds like you have the leads reversed or the unit is somehow different than the one you replaced.

SOURCE: 2006 Buick Rainier stalled. The oil gauge reads

Fairly common problem on the 03-06 Rainier instrument clusters, it's caused by failing stepper motor on the cluster's circuit board and it can be fixed. Check out this page for more on it - Rainier oil gauge broken

96 Chevy blazer how do I get out of safe mode ran low on oil now runs an drives but won't let car go fast past 2000rpms


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 !

If my 2004 chevy silverado oil pressure gage stays at 80 psi could this hurt the engine


I would want to know what the actual oil pressure is. The sending unit or the gauge on the dash could have failed.
There is a pressure relief valve to prevent oil pressure from going too high, but staying at 80psi would not be good for a long time.

Oil pressure guage not registering


The oil pressure gauge on a 2004 WJ doesn t really show the pressure, but it will go to a preset value when pressure is ok, or it will stay at o PSI. So you need a pressure switch on this jeep and not a pressure sending unit. If the right unit is installed, then or the pressure indicator is faulty, or wiring. Do a test of the instrument panel to see if the indicator works: ignition switch in off, press the odometer reset button and now switch ignition in run. Instrument panel will start a self test, all lights will come on and all meters will go full scale and return to normal.

Is the oil gauge in a 2006 1500 4 x 4 silverado suppose to at 80 all the time?


80 PSI is within operating range, but all the time would suggest that it stays there even after you turn your engine off and does not increase incrementally when engine is first turned on. If that is the case you have a faulty oil pressure sending unit or a stuck gauge.

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.

Oil pressure gauge reads 80 psi with engine off and pegs running


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.
