P0496 on Saturn
Evaporative Emission System High Purge Flow
P0496 on Saturn vehicles indicates evaporative emission system high purge flow. Au7o has documented this code across 1 Saturn model — most commonly on Aura. P0496 means the evaporative emission (EVAP) system detected high purge flow — fuel vapor is flowing into the engine when it shouldn't, typically because the purge valve is stuck or leaking open. The EVAP system captures fuel vapors in a charcoal canister and meters them into the intake through the purge valve at the correct times; unexpected vapor flow can create a vacuum in the tank and disturb fueling. Symptoms can include rough or stalling idle (especially after refueling), hard starting, or a fuel tank vacuum noise when the cap is removed. Typical repair costs on Saturn range from $100 to $350, depending on the specific model and root cause.
Common Causes of P0496
- •Stuck-open or leaking EVAP purge valve/solenoid
- •Faulty purge valve electrical control or wiring
- •Damaged or disconnected purge vacuum hose
- •Faulty vent valve allowing improper flow
- •Failed fuel tank pressure sensor
- •Cracked or pinched EVAP lines
- •Carbon canister saturation or failure
P0496 on Saturn by Model
Saturn Aura(1 issue)
- EVAP Canister Purge Valve Failure (Check Engine Light)2007-2009
Auras commonly throw EVAP emissions faults, most often from a stuck-open or failing canister purge solenoid/valve (and sometimes a clogged charcoal canister or faulty fuel-tank pressure sensor). The result is a persistent check engine light and potential emissions-test failure. The gas cap is worth checking first but is usually not the cause of the P0496 flow-during-non-purge code.

What does P0496 mean on Saturn?▼
P0496 stands for "Evaporative Emission System High Purge Flow." P0496 means the evaporative emission (EVAP) system detected high purge flow — fuel vapor is flowing into the engine when it shouldn't, typically because the purge valve is stuck or leaking open. The EVAP system captures fuel vapors in a charcoal canister and meters them into the intake through the purge valve at the correct times; unexpected vapor flow can create a vacuum in the tank and disturb fueling. Symptoms can include rough or stalling idle (especially after refueling), hard starting, or a fuel tank vacuum noise when the cap is removed. On Saturn specifically, this code is documented across 1 model.
