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.
    • Measuring oil pressure. Reprinted with permission.
    • 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.

SOURCE: oil pressure sensing switch location

The oil switch is located on the passenger side of the truck in the back of the engine. Look for the transmission dipstick, then feel for it between the transmission dipstick and the engine block. It is hidden pretty well, but a socket wrench will fit to take it off. The new part uses a 1-1/16 socket, the old part for some reason was smaller, I think 13/16 inch. Hope that helps.

Oil pressure switch location on isuzu dmax 2005 3.0 l
The oil pressure switch on a 2005 Isuzu Dmax with a 3.0L engine is located on the engine block, near the oil filter. Here are some steps to locate the oil pressure switch:
  1. Locate the oil filter on the engine block. The oil pressure switch is typically located close to the oil filter.
  2. Look for a small electrical connector attached to a sensor located on the engine block. The oil pressure switch will have an electrical connector attached to it, which distinguishes it from other sensors located in the same area.
  3. Follow the wire from the electrical connector to the oil pressure switch. The oil pressure switch will have a wire leading from the electrical connector to the switch itself.
Once you have located the oil pressure switch, you can replace it if it is faulty or damaged. It is important to ensure that the engine is not running and that the oil has cooled down before attempting to replace the switch to avoid injury. Additionally, make sure to disconnect the battery to avoid any electrical shocks.

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.

My oil light came on yesterday and I checked the oil. It was empty, it never has had to have oil added to it between changing and now it's empty. Someone told me it might be the oil sendor, so I want to...
Hi,
Sounds like the oil light and sender are doing their job. They are telling you, you are losing oil pressure. That will happen if you are low on oil or have pressure problems. Add oil and see if the light goes out and pressure returns. You may have leaks or a worn out engine.

Fig.: Oil pressure switch (sending unit) schematic


The low oil pressure warning lamp will illuminate when the ignition switch is turned to the ON position without the engine running. The lamp also illuminates if the engine oil pressure drops below a safe oil pressure level. To test the system, perform the following:

  1. Turn the ignition switch to the ON position.
  2. If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
  3. If the wire at the connector checks out OK, pull the connector loose from the switch and, with a jumper wire, ground the connector to the engine.
  4. With the ignition switch turned to the ON position, check the warning lamp. If the lamp still fails to light, check for a burned out lamp or disconnected socket in the instrument cluster.

REMOVAL & INSTALLATION
On the 2.4L engine, the oil pressure switch is located on the side of the engine block facing the firewall. On the 3.0L engine, the oil pressure switch is located on the oil filter adapter housing, next to the starter motor. On the 3.3L and 3.8L engines, the oil pressure switch is located next to the oil filter.
  1. Locate the oil pressure sending unit on the engine.
  2. Disconnect the negative battery cable.
  3. Disconnect the pressure switch electrical harness.
  4. Using a pressure switch socket, deep-well socket or wrench, loosen and remove the pressure switch from the engine.
To install:
  1. Install the pressure switch into the engine and tighten securely.
  2. Attach the electrical connector to the switch.
  3. Connect the negative battery cable.
  4. Start the engine, allow it to reach operating temperature and check for leaks.
  5. Check for proper oil pressure switch operation.

Oil pressure switch location on 1999 chev cavalier
The oil pressure switch relays the oil pressure in the engine to the instrument cluster. The switch will illuminate the OIL PRESSURE light if the oil pressure drops below 2psi (13 pa). The switch is usually located on the side of the engine, under the intake manifold on the 2.2L engine and on the side of the intake camshaft housing on the 2.3L/2.4L engine.

The oil pressure sensor is bad most likely. I can't see aany reason the sensor would cause the engine to blow up, other than it wasn't threaded carefully and it leaks oil until it is bone dry, and locks up the pistons.
They also get damaged because the heat shield isn't installed, because it can be a hassle, and they over heat, which ca also cause the seal to fail and the oil to leak out the sensor.
As long as the car has oil pressure, it will not be dangerous for the engine because this sensor doesn't work right.
Good Luck!

The oil pressure light stays on in my 1990 mr2
First thing, make sure you have oil pressure - extremely important.

Find oil pressure sensor under the hood - it will be low and possibly around the filter area.
Remove sendor
Insert a mechanical pressure gauge - get at auto store.
Verify you have pressure

Yes - replace the electric light sendor
No - You need to replace the oil pump -

Don't run car without oil pressure - will wear the engine out extremely quick

You can also do a quick check on light circuit.

Disconnect the wire on top of sensor and see if light goes out. Usually these are a grounding device in sensor.

Yes - The indication or no oil pressure or sendor bad - see above.

No - you just have an electrical problem - short in the cable from light to sendor, but I would also check the pressure mechanically to make sure.


Regards,


Doug
