Faulty oil pressure gauge?

[j91z28d1]

The 2012 probably has a PID that reads oil pressure in psi.

if anyone needed the pid to add to ae app that allows it

data stream location for this Gen gm: 221470
equation :A*0.578
min max is just 0 to 100.

put that in torque app or car scanner of you need oil pressure data

If you have Torque Pro and the extended GM PIDs it's already available:
