Abstract

Error code P0468 indicates that the engine control module (ECM) has detected a high voltage signal from the purge flow sensor in the evaporative emission (EVAP) system. This typically means the purge flow sensor is reading more airflow than expected, which can be caused by a faulty sensor, a stuck-open purge valve, or a wiring issue.
