The test is to connect an external gauge to the oiling system and get a reading there. if normal pressure, the sender (transducer) would be suspect, if pressure is too high, further surgery is required, typically a pressure relief valve got jambed. Jambed is very rare, and I would want to know why...
The transducer, which changes the pressure into a voltage value, does fail eventually, and typically is inexpensive to replace.
The oil that you use should be exactly what is specified on oil cap or manual, and no higher or lower weight.

Testimonial: "Thank you for advise. Very helpfull."
The oil sending unit is located on the engine block behind the drivers cylinder head area.You have to climb up on the motor to see it cause it is hard to see behind the wiring harness.You may also want to purchase a new sending unit because it is very long and you might need to buy the sending unit socket to replace it.Hope this helps.Good luck.
