P0458 Description


The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.
