Code P0458 Chevrolet Description

The Evaporative Emission (EVAP) Purge Solenoid Valve is used to purge fuel vapor from the EVAP canister to the intake manifold. The EVAP purge solenoid valve is Pulse Width Modulated (PWM). Ignition voltage is supplied directly to the EVAP purge solenoid valve. The Engine Control Module (ECM) controls the solenoid valve by grounding the control circuit with a solid-state device called a driver. The driver is equipped with a feedback circuit that is pulled up to a voltage. The ECM can determine if the control circuit is open, shorted to the ground, or shorted to a voltage by monitoring the feedback voltage. The Diagnostic Trouble Code (DTC) will be set when the ECM detects the EVAP purge solenoid valve control circuit is shorted to the ground within 0.25 s.
