Detailed Description

Standard Ignition CP454 is an emission control component used in the EVAP system to manage vapor flow at the canister vent circuit. The unit uses a female connector, two terminals, and a three-port layout with a 5/8 in. hose connection, making it suitable for service on the Chevrolet Silverado 1500, Silverado 2500 HD, GMC Sierra 1500, and related GM platforms shown in the fitment list.
