how to fix this problem where is canister

Answer 1

Hi there,

This code is for the vent control valve on the charcoal canister. This is the most common cause when you have this code. The canister is under the truck on the rail between the two side rails of the frame, just ahead of the gas tank. The vent valve on these actually isn't bolted directly to the canister, but is on the frame rail next to it.
