Hello all...Because I'm an idiot I need to recalibrate my OIL pressure gauge up in the pods above the radio. Is it possible to get your oil pressure through an OBD-II reader? If not, how would I go about getting a reading on the oil pressure?

 

I have a test gage I use to screw into the block or what ever the case may be and it is Mech. so it is 100% accurate. What is ur oil press reading? I dont know that the gage can be calibrated. Possibly the sending unit

 

How did you screw it up in the forst place?
