Code P0458 2016 GMC Sierra Description
The P0458 diagnostic trouble code (DTC) for a 2016 GMC Sierra relates to the Evaporative Emission (EVAP) Purge Solenoid Valve Control Circuit registering a low voltage. The EVAP system is responsible for capturing and storing fuel vapor emissions from the fuel tank to prevent them from being released into the atmosphere. The purge solenoid valve controls the flow of vapor from the charcoal canister to the engine intake manifold for combustion. The low voltage detected by the vehicle's onboard computer indicates a problem with the electrical circuit controlling the purge solenoid valve.
