Q: How to replace the Canister Purge Valve and Vapor Canister for the Honda Ridgeline?
A: The Evaporative Emissions Control (EVAP) system stops fuel vapors from polluting the atmosphere. On hot days, these vapors expand in the fuel tank until a certain pressure is reached. They're then routed through valves and the EVAP canister for temporary storage. When conditions allow, the PCM opens the canister purge valve, letting vapors mix with the air/fuel mixture to be burned. The EVAP system includes the canister, filter, vent shut valve, two-way valve, bypass solenoid valve, and fuel tank pressure sensor. Symptoms of a faulty system include fuel odor and poor engine performance. Professional troubleshooting and replacement is recommended.
