Here we go again! This time we are tackling an 08' Trailblazer with a P0455, Evap gross leak fault code. I cover how to recognize and identify evaporative emissions system leaks, and go over some pertinent information relative to most GM Evap systems. The troubleshooting procedure used to diagnose this vehicle can be applied to nearly all GM vehicles utilizing evaporative emissions leak detection, as well as countless other vehicles utilizing key-on systems via a purge and vent solenoid. Thanks for watching!
