Yes, a faulty purge control valve can lead to increased fuel consumption in a Suzuki Cultus. Here’s how:

Stuck Open Valve: If the purge valve is stuck open, it will allow excessive fuel vapors from the charcoal canister into the engine’s intake manifold. This disrupts the air-fuel mixture and can cause the engine to burn more fuel than necessary, resulting in higher fuel consumption.

Improper Vapor Flow: If the valve doesn’t regulate vapor flow properly, it can make the engine run inefficiently. When the engine is forced to deal with inconsistent fuel vapor intake, it can increase fuel usage.

Poor Combustion: An imbalanced fuel-to-air ratio caused by the purge valve malfunction can lead to incomplete combustion, which in turn reduces fuel efficiency and increases fuel usage.

Drivers may notice that they need to fill up their tank more frequently, which is a sign of this issue.
