Review on Vapor Canister Purge Valve Solenoid 1997278 For Chevrolet Trailblazer, Cavalier, Pontiac Bonneville, Oldsmobile - Replaces 214-641, 214-2246, 911-035 - EVAP Emission Purge Control Valve by Kevin Griffin

Works. Good Price. Fits 2002 Chevy Tahoe Z71 most likely cause for EVAP code but to be sure always do the proper tests. Often the issue is intermittent though so it is not always easy to test sometimes the valve works other times it gets stuck open for me I just guessed this is what was happening for the price it was worth saving a little time in doing the testing I thought and as luck would have it I was right. Other potential fixes may be leaky or cracked lines or other faulty parts in the evap system but this is the number 1 cause it seems.
