Code P148F 2022 GMC Sierra Description

Purge capacity is being reduced by technologies that improve fuel economy. The Evaporative Emission Purge Pump is used to purge stored vapors from the Evaporative Emission Canister and is required to increase the purge volumes to meet LEV 3 Evaporative Emission requirements. The Evaporative Emission Purge Pump has an integral pressure sensor for controlling purge vapors from the canister. The Engine Control Module (ECM) monitors the Evaporative Emission Purge Pump, and the Diagnostic Trouble Code (DTC) will be set when the EVAP Purge Pump Voltage is greater than 28.0 V for greater than 1 s.
