A faulty purge control valve in a Suzuki Cultus can cause a variety of symptoms related to engine performance and fuel efficiency. Some common signs include:

Check Engine Light CEL: A malfunctioning purge valve often triggers the check engine light. If you see this light on your dashboard, it could be due to a valve issue.

Rough Idling o r Stalling: The purge control valve regulates the flow of fuel vapors from the charcoal canister to the intake manifold. If it’s stuck open o r closed, the engine may experience rough idling o r stalling, especially during stop-and-go driving.

Poor Fuel Efficiency: The faulty valve may cause the engine to run less efficiently, leading to an increase in fuel consumption. Inconsistent fuel vapor flow could affect how the engine burns fuel.

Difficulty Starting the Engine: If the purge control valve is malfunctioning, it may cause the engine to have trouble starting due to improper vapor flow.

To confirm the issue, a diagnostic scan tool can be used to check for specific trouble codes like P0441, P0446 related to the purge control valve.
