TYPICAL MALFUNCTION THRESHOLDS
P0455: EVAP gross leak
P0456: EVAP 0.02 inch leak
CONFIRMATION DRIVING PATTERN
NOTICE:
- The Evaporative System Check (Automatic Mode) consists of 5 steps performed automatically by the Techstream. It takes a
maximum of approximately 18 minutes.
- Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be
closed, making the fuel tank leak check unavailable.
- Do not run the engine during this operation.
- When the temperature of the fuel is 35锟斤拷C (95锟斤拷F) or more, a large amount of vapor forms and any check results become
inaccurate. When performing the Evaporative System Check, keep the fuel temperature below 35锟斤拷C (95锟斤拷F).
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/DTC Check / Clear.
- Turn the engine switch off.
- Turn the engine switch on (IG) and turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode [A].
