Purge Control Solenoid Valve (PCSV)
WARNING: This page is about a different variant/trim than selected.
The evaporative emission control system prevents hydrocarbon (HC) vapors in the fuel tank from escaping into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The PCM controls the Purge Control Solenoid Valve (PCSV) to purge any collected vapors from the canister back to the engine for combustion. This valve is actuated by the purge control signal from the PCM and controls fuel vapor from the canister to the intake manifold.
