How to Replace the Vapor Canister Vent Solenoid in a Few Simple Steps
The vapor canister vent solenoid is a part of your car's evaporative emissions control (EVAP) system, which plays the essential role of purging the vapor from the fuel tank and venting it out into the engine for combustion. A failing vapor canister vent solenoid isn't really unusual since it's considered as one of the EVAP system components that easily get damaged. It's prone to getting stuck open or clogged due to foreign debris. Once this component fails, expect it to trigger the Check Engine light on your dashboard. Fortunately, you can replace it immediately by following these easy steps:
Difficulty level: Moderate
What you'll need:
- Floor jack
- Jack stands
- Ratchet and socket set
- Replacement vapor canister vent solenoid
- Owner's manual
Step 1: Guarantee your safety first by parking your car on an area with a nice and even flooring to ensure that it won't shift while you're working on your car's EVAP system. It's also highly recommended that you do this procedure on a well-ventilated place that's free from combustible materials.
Step 2: Pop up your car's hood and detach the negative cable from the battery to avoid electrocution.
Step 3: Place the floor jack under the rear part of your vehicle and slowly raise it up until you've made a comfortable space under your car where you can crawl into. Support your car's rear end with the jack stands.
Step 4: Once you've made sure that your car is safely propped up over the jack stands, carefully slide under it and locate the vent solenoid. It's usually mounted around the fuel tank. If you're having trouble finding it, simply consult your owner's manual to see its exact location.
Step 5: Disconnect the electrical wirings that are attached to the terminals of the damaged vapor canister vent solenoid. Remember to work carefully to keep the wires from getting damaged.
Step 6: Remove the hose fitting that's also attached to the vent solenoid. You can do this by simply squeezing the retainers before taking the fitting off the assembly.
Step 7: After you've gotten the hose fitting and electrical wirings out of the way, you may now remove the damaged vapor canister vent solenoid from its mounting location. The fasteners that are holding it in place may vary for every vehicle. Some vent solenoids are held with screws or retainers. Make sure that you have your basic hand tools near you just in case you need them.
Step 8: Carefully remove the fasteners that are used to secure the damaged vent solenoid onto the bracket. Pull it off from the vehicle and set it aside.
Step 9: Get your new vapor canister vent solenoid and install it on the bracket where you removed the old one. Make sure that you securely fastened it into place to ensure that it won't fall off while you're driving.
Step 10: Reattach the components that you removed earlier, including the electrical wirings and the air hose. Make sure that you place them back tightly to avoid any complications.
Step 11: Lower your vehicle and reconnect the negative cable of the battery.
Step 12: Test if the system is now working as it should be. The Check Engine light should no longer be illuminated once you turn on the engine.
This easy replacement procedure takes just around 30 minutes to finish.
