To all of you that have OBDII based apps/scantools that display engine data, do any of them display oil pressure and/or oil temperature?
^Yep! You'll find oil temps hover between 240-260 when fully warmed up. Pretty tough on non-synthetic oil.I have the paid version of Torque on Android and it shows my oil temp and coolant temp.
You might have to download the GM PIDs/sensors in the settings.

Looks like it may just be a low pressure switch.I don't think there is a pressure sensor in the motor, only a switch for a dummy light. The Dashhawk reads pressure on other vehicles I've had it on.
