Code P148E 2019 Chevrolet Silverado 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.
