Where can you find a diagram for the oil pressure gauge sensor switch for a 1988 Ford 150?

There is no need for a diagram. That is the simplest wiring system in the world. It has one wire. The wire that attaches to the oil sender goes all the way back to the gauge. The sender is a variable ground, so the gauge picks up it's ground from that wire. That ground variates depending on how much oil pressure there is. The gauge gets it's positive power from inside the cluster itself where it plugs into the circuit board of the cluster. The system is also elementary to test. Unplug the sending unit, ground the wire end, turn the key on, and see if the gauge sweeps to high. If it does, then all the wiring power supply and gauge are good. You are left either with a bad sending unit, or the engine is not building enough oil pressure to register. If it doesn't then you have something wrong after the sending unit, possibly a gauge. If that is the case, pull out the gauge, turn the key on, ground the wire end again, and check the pins where the gauge plugs in for power on one pin and ground on the other. If you have both, you have a bad gauge. If you are missing power or ground, then you will need to see where you are losing it. I doubt you will get thet far though. 99% of the time, you will find a bad sending unit, and you probably wont have to go past step one in your diagnosis.

Faulty sensor was one answer for low oil pressure so what sensor could it be?
normally the oil pressure switch is on the main block if you have a pressure guage or oil pressure light on the car if you disconnect the right switch the gauge will drop or the light will go out then you know that's the switch to change.
Do you need a fuel tank pressure sensor for gas gauge to work?
The fuel tank pressure sensor is for the EVAP system. It has nothing to do with the fuel gauge sending unit.
How do you replace the oil pressure switch on a 3.8 liter Buick?
A Buick with a 3.8 liter engine does not have an oil pressure switch. There is an oil pressure gauge. The gauge can be accessed by removing the dashboard panel. Unhook the wiring harness to the gauge. Reverse the process to replace the gauge.
Can you replace stock oil pressure sensor on 97 Saturn with oil pressure gage for poundage info?
The stock oil pressure sensor on a 97 Saturn can be replaced with an oil pressure gauge for poundage info by first unscrewing the existing sensor. The new sensor can then be screwed into place and wiring ran to a suitable pressure gauge.
What does the oil pressure sensor do?
Obviously asits name implies it senses oil pressure. If it is for a gauge it usually is a device that changes resistance or generates a voltage as the pressure on it changes. If it is for a warning light it is usually a spring loaded switch.
Bad oil pressure switch?
Either replace with a known good switch or with a manual oil pressure gauge
How do you tell if oil pump Is bad or is it the sensor?
You can pressure test with a gauge using sensor location
Why is the oil gauge in your 1991 Pontiac le sunbird always at its peek?
Check with manual gauge - if pressure normal - could be defevtive oil pressure sensor or gauge
Where does the oil pressure gauge get its reading from on a 2002 Envoy. There does not appear to be an oil pressure sensor only a pressure switch and an oil level temperature sensor?
The gauge cluster gets its information from the PCM (computer) It is a kind of fancy idiot light. It basically gives you readings based on signals that are in increments. None - low - medium - high etc. It cannot be considered an accurate gauge. It will tell you if you are without oil pressure and will tell you if it is higher or lower at any given point of driving.
Oil pressure gauge not working?
replace oil sensor unit
What does an oil pressure switch do in a 1997 Cadillac Catera?
oil pressure switch sends message to oil pressure gauge in dashboard,telling what the oil pressure in engine is
What is a oil sending switch?
This is a pressure sensitive switch that controls the oil pressure indicator (light or gauge) on the dash board in the vehicle
