P1491 is a diagnostic trouble code (DTC) specific to the Jeep Grand Cherokee, indicating a problem with the evaporative emission control system (EVAP). This code typically means that there is an issue with the EVAP canister purge valve, which can cause the vehicle to fail emissions tests or trigger the check engine light. It may result from a malfunctioning valve, electrical issues, or vacuum leaks in the EVAP system. Addressing this code usually involves inspecting and repairing the EVAP components or their connections.
