low oil pressure light is on, came on after i did an oil change and oil filter change, i than changed the oil pressure switch/sensor. light still comes on. i have oil flow to my top engine internals. so my oil pump is working. i need to check my oil pick up unit and my oil pan is hard to remove. need info on how to fix this problem
It could be the connector to the oil pressure switch.
You also may have installed the wrong filter…
I’d get a mechanical gauge, remove the pressure sensor and install it in that hole. Start the car. Is there ENOUGH pressure?? If there is, the sensor or the wiring to the sensor is the problem. If there ISN’T enough pressure, you need to find out why.
