How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my evaporation vent solenoid replacement?

You can check your owner’s manual or ask your mechanic for precise parts, but here’s a general rundown:
  • Evaporation (EVAP) vent solenoid: The evaporation vent solenoid collects and recirculates emissions from the EVAP filter. It is the main component in the replacement, and it will usually cost you $40 to $100.
  • Vent hoses: There are typically two vent hoses connected to the vent solenoid. It is not required that you replace them with the solenoid, but it can be a good idea, especially if the old hoses are frayed. Vent hoses generally cost $25 to $75. 
Some reputable brands we recommend for reliable EVAP vent solenoids are AC Delco, Dorman, and Standard Motor Products. Some brands we recommend for vent hoses include Gates, ACDelco, and Motorcraft. You can typically purchase these brands from retailers such as AutoZone and RockAuto, both online and in-store. However, like price, recommended brands may also vary depending on your vehicle's specific year, make, and model.
Depending on your vehicle, OEM evaporation vent solenoids can be similarly priced as their aftermarket counterparts. Plus, OEM parts are guaranteed to fit your vehicle and often come with a warranty. 
If you’d rather not purchase OEM parts for your vehicle, do your research—and consult a mechanic if needed—to find reliable aftermarket parts that work for your car and your budget.
You can buy parts for your EVAP vent solenoid from the following: 
  • The manufacturer/dealership
  • Auto parts shops and auto body retailers (like AutoZone and RockAuto)
  • Online retailers (such as Amazon or eBay)
The dealership or manufacturer will only sell OEM parts, while online retailers will only have aftermarket parts available. However, auto parts shops and retailers will likely have both OEM and aftermarket parts for sale.

How will a mechanic replace my evaporation vent solenoid?

To perform an evaporation vent solenoid replacement, a mechanic will complete the following steps:
  1. Preparation: Your mechanic will disconnect the battery and elevate the vehicle to gain access to the evaporation vent solenoid
  2. Remove parts: Next, your mechanic will remove the electrical harness and vent hoses.
  3. Remove the evaporation vent solenoid: Your mechanic will remove any bolts and clips holding the solenoid in place and then remove the faulty evaporation vent solenoid.
  4. Install the new evaporation vent solenoid: At this point, your mechanic will install and connect a new evaporation vent solenoid and secure it with clips and bolts.
  5. Reassembly: Your mechanic will reassemble any removed parts during the replacement, including the electrical harness and vent hoses, and reconnect the battery.
After the replacement, your mechanic will restart the vehicle and clear any engine codes sent by your car’s computer.

What happens if I don’t replace my evaporation vent solenoid?

Not replacing the evaporation vent solenoid will likely not cause serious damage to your car, but you may have to deal with poor engine performance—rough idling and trouble starting the engine—and your vehicle will likely fail an emissions test. In rare cases, raw fuel might enter the intake system and damage the catalytic converter—which could result in some hefty repair costs.
Fuel vapors could also enter the atmosphere and the vehicle’s cabin, which can pose health concerns.

What is an evaporation vent solenoid?

The evaporation vent solenoid, which is monitored by the engine control module (ECM), is an important part of your car’s evaporative emissions control system, which manages fuel vapors that form in the gas tank. The job of the evaporation vent solenoid is to bring air into the charcoal canister to keep the EVAP functioning properly.
When open, the evaporation vent solenoid brings clean air into the system, which is pressurized and helps deliver fuel vapor to the engine. When the vent solenoid is closed, the engine control module performs a pressure test.
If everything is working correctly, the control module should sense no drop in pressure.

When should I replace the evaporation vent solenoid on my car?

You should take your car to an automotive repair shop for an inspection if you notice the following warning signs:
  • An illuminated check engine light: Your check engine light will activate if your engine control module (ECM) detects a problem with the EVAP system.
  • Pressure inside the gas tank: If there is a large burst of air when you remove your vehicle’s fuel cap, there is excess pressure inside the fuel cell.
  • Apparent full tank when refilling: When refueling your vehicle, the gas nozzle might constantly click off, even though your tank isn’t full yet. 
  • A failed emissions test: Since your EVAP vent solenoid helps regulate emissions, your car could fail an emissions test without a functioning solenoid.

How often should an evaporation vent solenoid be replaced?

Unlike your vehicle’s wiper blades or oil filter, evaporation vent solenoids won’t be listed under your vehicle's regular
maintenance schedule
. EVAP vent solenoids can last the lifetime of your car, but like any automotive component, they’re susceptible to wear and tear. 
Regularly check for warning signs of a faulty EVAP vent solenoid and take your vehicle to a mechanic if you suspect you’re in need of a replacement.

Can I replace my evaporation vent solenoid myself?

You can complete your evaporation vent solenoid replacement at home if you have the right tools and DIY auto repair experience, but remember that it’s vital to your vehicle’s overall performance to complete the job correctly.
