To test an oil pressure sending unit, first disconnect the electrical connector and use a multimeter to check for continuity. Then, remove the sending unit from the engine and submerge it in a container with oil. Using a manual pressure gauge, apply pressure to the sending unit and observe if the gauge reflects the pressure accurately. If the sending unit fails to show the correct readings or continuity, it may need to be replaced.

To test the oil pressure sending unit in a 1989 Ford F250, start by disconnecting the electrical connector from the sending unit. Use a multimeter to check for continuity; a good unit should show continuity when the engine is off and change as the engine runs. Alternatively, you can use an oil pressure gauge by removing the sending unit and installing the gauge in its place to directly measure the oil pressure while the engine is running. If the gauge shows normal pressure but the sending unit does not, the sending unit may be faulty and should be replaced.
