I'm looking for the list of PIDs that Chevy was using on 2005 for their VPW based ODB-II vehicles. I'm really interested in the mode $22 pids (private pids). I know scan tools have it, but I just want the PIDs not the tool, and I was hopping to invest $100s not $1,000s.

Any contacts at Chevy to start with, or have they made to '05 pids public since VPW is no longer used?

I have plenty of DTC data... I'm just after the PIDs to gather real time telemetry.

As in PID$22 Fuel Rail Pressure (relative to manifold vacuum) Min: 0 Max: 5177.265 kPa Formula ((A*256)+B) * 0.079 ?


Its what I found on Wikipedia...

http://en.wikipedia.org/wiki/OBD-II_PIDs

 

Not quite... that is mode $01 PID # 222.

Here's what I've dug up on google so far:
ref: http://www.scangauge.com/wp-content/upl ... Coding.pdf
ref: OBD-II PIDs - Wikipedia, the free encyclopedia
ref: GM Specific : Linear Logic : Home of the ScanGauge
ref: X-Gauge : Linear Logic : Home of the ScanGauge ... -vehicles/
ref: http://www.fastfieros.com/tech/vpw_comm ... otocol.htm

so, for example mode $22 PID #1940 is tranny temp.
