Simplify. you just were in the engine compartment... did something get disturbed, unplugged, look at the temp sender and the oil sender, they have been the most likely causes of concerns of this type since electric indicators replaced gauges years ago. does your system have a tripminder or indicator for changing the oil? does it get a reset during the service? if yours has that there may be a mode that its in...but not fully reset.. then theres a question about..does your body control ecu have a self test mode? or your powertrain control? these can be read for codes for free as a preliminary check at a local parts store.

SOURCE: Oil gauge high

The pressure will depend on the temp. of the engine, and the RPM's. Just make sure you have the correct amount of oil in your engine. I wouldn't worry about the pressure until it gets too low, then your almost out of oil. Mine currently stays above mid-point as well.

Drop the tin sump and check the pick up pipe as the pipe can crack and the seal goes hard so lets some air air in for a bit .

Drop the small tin sump down and look at the longer of the pick up pipes for a bad O seal or cracking .
This lets the pump pull in air so you dont get pressure - some times they even fall right off .

Temperature gauge not working


Hi there,
My name is Steve. I can tell you that the barometric pressure sensor can, in no way, effect the temperature gauge operation. The gauge gets a signal from the engine computer which, in turn, gets a reading from the coolant temperature sensor. Your first step should be to have the check engine light diagnosed properly...starting with checking for codes. You likely have a code(s) relating to engine temperature or the temperature sensor circuit. Most common problems are erratic sensor operation and corrosion or oil contamination in the coolant temperature sensor connector. You will be time and money ahead by having a professional diagnose the problem correctly before deciding to buy any parts.

When stopped at a stop light my oil gauge goes down and my temperature gauge goes up on my 94 Chevy 1500 truck. I just changed the oil yesterday? What could it be?


Both issues could be normal to a degree. The engine temp would go up some when the truck stops moving, and the oil pressure would go down some when the engine returns to idle.
Are the two gauges reading out of normal range ?

My oil pressure, temperature, volt gauges, turn signals, and center console switch for rear window have stopped working. Fuse or relay?


Both? A 7.5A "Gauge" fuse provides power for the oil press, temp, volt, and the solenoid coil for the rear window relay. The actual power for the rear window comes from somewhere else probably the 30A Power CB.

The oil pressure guage on my 2000 Jeep Grand Cherokee is registering 0. My oil was just changed and I don't see any indication of oil leaking anywhere. Could it be the sensor?


First off I wouldnt drive your car until you make sure that you have indeed oil pressure and that the gauge is a false reading, driving your car if in fact it has no oil pressure will severly damage your engine, but firstly i would check the oil pressure switch its located on the passenger side of the engine right back from the oil filter make sure the connector is clean and free from oil and corrosion if the connector appears to be in good shape take a paper clip and insert it between the 2 terminals inside the connector your oil pressure gauge should peak at 80 PSI that tells you that your gauge and all related wiring are good and in working condition, secondly remove the oil pressure switch and hook an manual oil pressure gauge up to you engine and start the engine the guage should have a oil pressure reading anywhere from 30 PSI to 55PSI depending on engine temperature if theres oil pressure on your manual gauge replace the oil pressure switch with a new unit, if you still have 0 PSI on your gauge then stop your engine immediatly and start looking at your oil pump and lubricating system for a problem.

Why won't the oil and temperature gauge work on


you should switch the temperature sensor and oil pressure sensor you had on your first engine,because your new engine must come with the light indicator dashboard so the sensor of your new engine are not compatible with your gauges....lipak!...

Oil light blinks on and off could pressure switch be bad if so where is it located on a 2000 ford windstar 3.0


Oil Pressure Switch Operation:
00134_oil_pressure_switch_gauge.jpgInformation relay unit for the indicator light or gauge on instrument panel. It contains a diaphragm that responds to changes in oil pressure. When the oil level is over a pre-set limit, the diaphragm opens the switch, turning off the light. When level is below the pre-set limit, the dash light comes on. In later model cars, if the oil pressure drops, the switch turns off the fuel pump, to stop the engine and limit damage to internal parts. Oil pressure switches can be grouped into two categories, units for electrical gauges and for mechanical gauges.

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.
WARNING 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.

Guages on 87 olds cutlass are not working properly. fuel does not work, temperature works but goes strainght to hot as soon as the car warms up, amp gueage discharging oil pressure not working


Hi, you will have to replace all sending units for these gauges in order to restore them to there original state. i will list the sending units and there respective locations below.

1. Fuel gauge sending unit- you will need to replace the fuel sending unit on your Olds. its located inside the actual fuel tank. there's a floater attached to this Assembly and , its broken. you will have to replace the entire assembly. you will also have to drop the fuel tank to access it as well.

2. Temp guage-- normally when this guage starts to malfunction, its because of a bad coolant temperature sensor. Inspect the sensor's wires and connections. ECT (engine coolant temperature) sensor problems are often caused by faulty wiring or loose or corroded connections rather than the failure of the sensor itself. If the wires or connections are bad, replace them. If you think the sensor is defective, it should be tested.

This sensor is located Under hood, center, upper engine area, front of carburetor, passenger side of water outlet, mounted in intake manifold.

3. Amp gauge --- OK, this can be caused by a bad voltage regulator. i would also trace every single wire from the amp gauge to the sensor and regulator. check for corroded connectors and contact clips. replace any wire that may seem worn.

4. Oil pressure gauge-- This gauge will malfunction if the Oil pressure switch is faulty or not working. This is an Information relay unit for the indicator light or gauge on instrument panel. It contains a diaphragm that responds to changes in oil pressure. When the oil level is over a pre-set limit, the diaphragm opens the switch, turning off the light. When level is below the pre-set limit, the dash light comes on. In later model cars, if the oil pressure drops, the switch turns off the fuel pump, to stop the engine and limit damage to internal parts. Oil pressure switches can be grouped into two categories, units for electrical gauges and for mechanical gauges. If this switch is defective, it will have to be replaced. Once replaced, it will fix the dead oil gauge.

This device is located Under the hood, passenger side, front engine area, mounted rear of water pump. If the wires are worn or there is an oil leak near the switch location, replace it.

Inspecting all the above areas and replacing parts if needed, will fix your gauge issues.

Please rate and god bless:)

Oil pressure on a 2004 5.3 liter silverado at idle is around 20


The pressure to be most concerned with is the reading in gear at idle with engine warmed up...Low end really should not be below 20. If pressure wanders, change the sending unit and check actual pressure with a mechanical gauge if necessary. The age and quality of your oil, as well as temperature all play a part in pressure, as well as internal wear from time & miles of use. If pressure changes with rpm, that is normal. 40psi is good while driving.
need more info just ask.
