Can a Faulty Purge Valve Lead to Increased Fuel Consumption in a Toyota Camry?

If the purge valve is malfunctioning, does it cause poor fuel efficiency due to improper fuel vapor recirculation? How can Camry owners track fuel consumption changes?

Yes, a malfunctioning purge valve can result in poor fuel vapor management, causing improper fuel vapor recirculation. This can lead to:

Increased Fuel Consumption: Unnecessary fuel vapor purging into the engine increases the workload on the engine, reducing fuel efficiency.
Inconsistent Engine Performance: Unbalanced air-fuel ratios can cause the engine to burn fuel inefficiently.
