Watch my video about oil pressure switches checking:
You want to focus on the pressure switch above the oil filter.... if the test light does not "light-up" by the time the engine reaches
2000rpm, you will get the warning buzzer in the dash.
If your oil light does not blink at the same time, then your Buzzer Warning Circuit Board is Faulty... it is located in the instrument cluster and
looks like this:
To check if the circuit board is at fault... disconnect the wire from the oil pressure sensor and attach it to a metal part of the engine (clean engine
ground connection). Start the engine and rev past 2000rpm. If the buzzer stays off, your oil pressure switch is bad, the wrong switch is installed
or you actually have low oil pressure.
