Has anyone found a working PID for GM Oil Pressure yet?
I have been looking through forums for the past month and have tries several different ones but they dont seem to work.
I can get all other gauges to work as needed but oil pressure.
Im running it in a race car on a touch tablet setup and dont realy want to install a gauge just for oil pressure.

Cheers

Its not a F body pcm, I have had another set of after market gauges connected to the same OBDII port and they are programed and do read oil pressure and when I get the vehicle dyno tuned they are able to read the oil pressure from the pcm.

Do you have an F-body PCM?
The F-Body PCM does not provide an oil pressure PID value. The PCM software reports that the oil pressure PID is supported, however the PCM does not provide oil pressure data for that PID. The oil pressure is sent directly to the instrument gauge.

The Y body(Corvette) oil pressure PID does report oil pressure.

The GM-H(G-8) Commodore oil pressure PID does report oil pressure.

I can’t say I’m absolutely positive that this isn’t true, but I can say with certainty, that almost all tuners are able to read the Oil Pressure on my 05 LM7 (5.3) with no problem, and that the tuner claims this is an OBD PID. What the PID is, I’ve no idea because tuners are assholes and refuse to share any info. But, DiabloSport definitely knows the PID and formula, FYI. It’s just waiting to be found and released publicly.

oil pressure is important but not much car had sensor back then

they just had a on off switch

since the only thing you could do with it … is put the value in gage that 99% of people don’t look …

Now with variable cam shaft and other stuff pressure is more important to the process so you may find a sensor
