Replacing Vent Valve Solenoid & Purge Valve Solenoid (EVAP Valve) 2005 GMC Yukon
When you get a check engine light, your parts store can test it with a
little electronic device - ask for the check engine light tester.
They go by many names, but look for EVAP Valve or Vent Valve/solenoid &
Purge Valve/solenoid. The one in the rear of the car, near the gas tank, is
known as the "Vent Valve Solenoid Canister." The one in the engine
compartment is called a " Purge Valve Solenoid."
Replacing the one in the engine compartment did the trick. I'd start by
replacing that one first then test it.
$25.97 Vent Valve Canister (fuel tank one)
$35.72 Purge Valve (engine compartment one)
GM Dealer quote: $281.00
I saved $219.31
