What is a canister purge solenoid replacement?

A mechanic will inspect the Evaporative Emission Control (EVAP) system in your car’s engine compartment and replace the canister purge solenoid, or purge valve, if it is not opening or closing correctly.
The canister purge solenoid helps direct the flow of fuel vapor. The vapor travels from a charcoal canister to the engine, where it is burned during the engine’s combustion process.
Your canister purge solenoid opens when the engine is running and closes when the engine is off. When the purge valve stops working efficiently, your engine may begin to experience various issues and stop running smoothly.

How to replace a canister purge solenoid

To perform a canister purge solenoid replacement, a mechanic will complete the following steps:
  • Lift the hood to inspect the engine compartment. This is located near the throttle body or on top of the charcoal canister in older models.
  • Disconnect the fuel vapor lines, vacuum, and electrical connector
  • Detach and remove the faulty canister purge solenoid from the engine compartment
  • Install and connect a new canister purge solenoid
  • Start the engine and check for any fuel vapor or vacuum leaks
Once everything looks back to normal, the mechanic will clear any engine codes sent by your car’s computer and restart the vehicle to make sure they don’t reappear.

When do I need a canister purge solenoid replacement?

If you notice your car’s engine is idling roughly or see that the check engine light has come on, you should take your car to a mechanic for a diagnostic inspection.
Common symptoms of a faulty canister purge solenoid are the check engine light turning on, rough idling of the engine, trouble starting the engine after refilling the gas tank.
Not replacing the canister purge solenoid will not cause serious damage to your car, but you may have to deal with rough idling, trouble starting the engine, and failing an emissions test.
