Hello everyone,
I have an 06 Trailblazer 4.2 with 96,000 miles that failed NY inspection for readiness on EVAP monitor and O2 monitor, when I scans the truck I’m getting emissions not ready, I’ve driven the truck 60+ miles and it still says not ready when I scan, the only DTC code I’m getting is PCM power control module P0856 traction control torque request circuit, I did disconnect the battery about a month ago when I put a new air-conditioning system in, any idea how many miles or drive cycles this takes before it’ll run emission test or do you think it’s something more serious? I don’t think the P0856 would have anything to do with it but maybe I’m wrong, I got a 10 day temporary inspection but any suggestions or thoughts on it or on the P0856 would be appreciated.
