J1850 VPW (Class 2) PID List

Does anybody know the correct PID number and mode for ENGINE OIL PRESSURE?
I'm trying to set some gauges using Torque Pro android app and a OBDlink MX bluetooth adapter.
All gauges work correctly but OIL PRESS doesn't. I loaded the GM predefined list and there is a OIL Press PID present but it doesn't work (PID 221470).
I can datalog it using HPTuners, it lists OIL PRESSURE as PID 2112, I tried it in both Dec and Hex with no success.

The vehicle is a 2005 Silverado, 5.3L with P59 PCM, 4L60E

I didn't think that the PCMs for the Gen 3 truck engines get an oil pressure signal.

I didn't think that the PCMs for the Gen 3 truck engines get an oil pressure signal.

The 1999 to 2002 Trucks didn't (they had a 1 wire Oil Pressure Sender), but the 2003 to 2007 (classic) Trucks did - they had a 3 wire Oil Pressure Sensor.

Well I just figured it out.
The correct settings are:


PID: 22115c
Min Value: 0
Max Value: 100
Scale: x1
Unit: psi
Equation: (A*0.65)-17.5
OBD Header: Auto


I found this in a GTO forum. Didn't think it was going to work but what the hell. Well it worked, the gauge in now displaying Oil Pressure, it follows the mechanical gauge +/- 4 psi. Going to tweak the formula a bit to get it closer.

Thanks
