2004 oil pressure pid?

hey guys,
I plan on firing up my S10 (1999 4.8 / 2004 harness,PCM,DBW) tom and id like to confirm the oil pressure gauge on the dash.

Is there a PID for oil pressure in a 04?
I dont have internet at the house so id like to figure this out before i fire it up.

Or can i log oil pressure sensor voltage and make a PID to log it?


If all else fails i can put a volt meter on it and watch the voltage.

I thought about checking the voltage on my 2000 silverado, but its only a 1? wire sensor instead of a 3 wire. that means the silverado is a ground referenced setup? and the 04 is a 5volt?

Thanks guys!!!!
