How to Replace the Sensor on an Evaporative Canister in a Hyundai Sonataby Cayden Conor
The Hyundai Sonata produces vapors when fuel evaporates in the sealed fuel tank. The evaporative emission control system, or EVAP, stops the uncontrolled release of these vapors into the atmosphere by routing them through the EVAP canister, which is filled with activated charcoal. The charcoal absorbs the vapors, and when you start the engine, the vapors get drawn through the purge control valve, into the intake manifold, and are then burned during the combustion process. The EVAP system should be inspected every 52,000 miles, according to AutoZone, and any malfunctioning components should be changed.
Open the hood and locate the canister close valve, or CCV, on the charcoal canister. The canister is located near the left or right front headlight, depending on the year Hyundai Sonata you have.
Loosen the clamp on the vapor hose, using the screwdriver. Pull the vapor hose off the valve.
Remove the CCV mounting bolts, using the appropriate socket, then pull the CCV off the canister.
Install the CCV and tighten the mounting bolts firmly. Reconnect the vapor hose and tighten the clamp.
