Question

2003 Saturn Vue 2WD 2.2L Ecotech 5 Speed Manual with engine code P0440 Evaporative System malfunction. Is it any specific part of the evaporative system??

Answer 1

HI there,

The evap system prevents fuel vapors from escaping. This code is not specific to any single part on the car or of the system. Basically it means there is a problem or a leak, but the computer isn't sure where it is. This could be the result of a faulty gas cap, a bad charcoal canister or a purge control valve. Usually to try and repair you start with a new gas cap then if that doesn't resolve it, doing a smoke test would be required.
