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.

SOURCE: 01 grand cherokee fan relay/oil pressure

I don't know if this will help anyone, but i had a issue with my jeep running hot and check engine light coming on as well. After alot of trips to different shops - the last one found that there were two senors in the engine for the fan that need to be changed. Everyone would aways fine the one up top but not the second one. After that, have not had any other problems like it since.

SOURCE: Leaking oil from oil pressure switch

I've seen pressure switches rust out and shoot a steady steam of oil out of them, so yes it could cause you to loose two quarts of oil. Book does not mention starter removal:
REMOVAL & INSTALLATION

  1. Disconnect the negative battery cable
  2. Raise and safely support the vehicle.
  3. Drain the engine oil.
  4. Disconnect the switch electrical lead and unscrew the switch. To install:
  5. Coat the first two or three threads with sealer. Install the switch and tighten until snug.
  6. Attach the electrical lead.
  7. Lower the vehicle.
  8. Connect the battery cable and fill the engine with oil.

SOURCE: 1988 Ranger, 2.3 , Oil light stays on. Where

For 1988 Ford Truck Ranger 2WD 2.3L FI 4cyl need to check two sending units:
* Low Oil Level sensor, that is located in the engine oil pan, on all models
* Oil Pressure Switch, that is located under hood, driver side, rear engine area, below end of valve cover, mounted in cylinder head.

Check this procedure to know about the first choice,
Low Oil Level sensor...

TESTING
(see Figures 1 and 2)

Use the accompanying diagnostic chart to help pinpoint low oil level sensor malfunctioning.

The ignition switch should be turned
OFF for a minimum of 5 minutes between checks to ensure that the electronic relay, which has a 5 minute timer, has reset.

Fig. 2: Low oil level indicator wiring schematic



REMOVAL & INSTALLATION
(see Figure 3)

Always install a new gasket whenever the oil level sensor is removed

  1. Turn the engine OFF .
  2. Raise the front of the vehicle and install jackstands beneath the frame. Firmly apply the parking brake and place blocks in back of the rear wheels.

Fig. 3: Typical low oil level sensor mounting-note: the sensor is constantly submerged in oil, therefore, drain some oil out of the engine before removing it

  1. Drain at least 2 quarts (1.9 liters) of engine oil out of the pan.
  2. Disconnect the sensor wiring.
  3. Remove the sensor from the oil pan using a 1 in. (26mm) socket or wrench. Discard the old gasket.
To install:
  1. Install a new gasket onto the sensor.
When installing the new gasket, the flange faces the sensor and the words "panside" should face the oil pan.
  1. Install the sensor and gasket assembly into the oil pan. Tighten the sensor to 13-20 ft. lbs. (17-27 Nm).
  2. Connect the electrical wire to the sensor.
  3. Lower the front of the vehicle and remove the wheel blocks.
  4. Refill the crankcase to the proper level.
  5. Start the engine and check for leaks.

Oil light comes on ,when oil is full.


The sensor may be bad. You may want to have the OCD codes read to see if a reset is necessary. If not, here is the replacement: http://www.nextdayauto.com/2005-ford-ranger-engine-oil-pressure-switch-v6-30-motorcraft-w0133-1815235.html

Location of oil sending unit on 1990 ranger 2.9


Here's a link to your oil pressure switch,here's the part.As you can see there are 2 types,one for light and one for gauge.
  • When the oil pressure is either high or low it will either turn the oil light "on" in the dash or move the gauge to the extremes
  • Undetected high or low oil pressure can result in internal engine damage and/or gasket leakage

Have no oil pressure in a 1998 ford ranger 3.0


If your gauge is not reading pressure and your engine is not making all kinds of noise while its running than I would bet that the oil pressure switch is bad.

How do you check the oil pressure switch?


If yr oil pressure gauge is not working properly then clean the wiring connection to the engine sensor usually on the engine block under or to the lower side of the engine. If u think it is the switch that is faulty then get a replacement put in as they will contiue to fail. cheers

Oil pressure problem


You oil pressure sending unit has gone bad, it's common to go bad and some even leak oil. 
The oil pressure sensor is on the back of the block on the passenger side, you can get to it from the top and not from the bottom. There are (2) switches back there that screw in to the block and you can only see it from the top of the engine. The Oil Pressure Sending Unit is the one wire harness with a green and white strip on it. The other switch has more wires to it. 
When you pick up the new sensor, make sure you get the right one. make sure you get the Oil Pressure Sending Unit which sends variable oil pressure and has only one quick connect for the wire connector. The oil pressure switch is the one that only activates the oil light on older engine
Once you get the right part at Auto Zone for around $9.00, disconnect the wire clip with the green with white strip on it. and use a deep spark plug socket with a extension and u joint to get the sensor out. The sensor comes with teflon tape already and no oil should leak out from the block. It as simple as replacing a bolt and reconnecting the wire connector. 
Good luck and hope this helps, take no more then 10 min to do but about 5 hours for the engine to cool off LOL

Oil pressure slow to rise


you need to try a external gauge to check the pressure to see if your dash gauge is right

if the engine took 10 minutes to get oil pressure it would be dead by now i would replace the oil pressure sender unit first
