Caution: Do not breathe the air through the EVAP component tubes or hoses. The fuel vapors inside the EVAP components may cause personal injury.
Important:
• | Perform a careful visual inspection of the evaporative emission (EVAP) control system components and the connecting hoses before diagnosis of an EVAP system malfunction. |
• | The EVAP canister purge system does not perform purging unless the engine is sufficiently warmed up and the heated oxygen sensor (HO2S) is fully activated. |
Important: The fuel tank pressure control valve that is original equipment manufacture (OEM) is black on the fuel tank side port, and orange on the canister side port.
