EVAP System: Procedure

  1. CONFIRM DTC 
    1. Turn the ignition switch off and wait for 10 seconds.
    2. Turn the ignition switch to ON.
    3. Turn the ignition switch off and wait for 10 seconds.
    4. Connect the Techstream to the DLC3.
    5. Turn the ignition switch to ON and turn the Techstream on.
    6. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
    7. Confirm DTCs and freeze frame data.

      If any EVAP system DTCs are set, the malfunctioning area can be determined using the table below.

      NOTE:

      If the reference pressure difference between the first and second checks is greater than the specification, the DTCs corresponding to the reference pressure (P043E, P043F, P2401, P2402 and P2419) will all be stored.

    NEXT: Go to next step 

  2. PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE) 
    NOTE:
    • The Evaporative System Check (Automatic Mode) consists of five steps performed automatically by the Techstream. It takes a maximum of approximately 19 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 and making the leak check of the fuel tank unavailable.
    • Do not run the engine in this step.
    • When the temperature of the fuel is 35°C(95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the temperature below 35°C (95°F).
    1. Clear the DTCs. Refer toDTC CHECK / CLEAR .
    2. Enter the following menus: Powertrain / Engine and ECT / Utility / Evaporative System Check / Automatic Mode.
    3. After the Evaporative System Check is completed, check for pending DTCs by entering the following menus: Powertrain / Engine and ECT / Trouble Codes.

      HINT: 

      If no pending DTC is displayed, perform the Monitor Confirmation (see appropriate "Diagnostic Help" service information menu). After this confirmation, check for pending DTCs. If no DTC is displayed, the EVAP system is normal.

    NEXT: Go to next step 

  3. PERFORM EVAPORATIVE SYSTEM CHECK (MANUAL MODE) 
    Fig 2: Identifying EVAP System Check
    GTY176893Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    NOTE:
    • In the Evaporative System Check (Manual Mode), the series of 5 Evaporative System Check steps are performed manually by the Techstream.
    • Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed and making the leak check of the fuel tank unavailable.
    • Do not run the engine in this step.
    • When the temperature of the fuel is 35°C(95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the temperature below 35°C (95°F).
    1. Clear the DTCs. Refer toDTC CHECK / CLEAR .
    2. Enter the following menus: Powertrain / Engine and ECT / Utility / Evaporative System Check / Manual Mode.

    *1 Canister *2 EVAP Pressure Tester Tool
    *3 Adapter *4 Disconnected Vent Hose
    *5 Canister Filter *6 Vent Hose
    1. Disconnect the vent hose.
    2. Connect the EVAP pressure tester tool to the canister with the adapter.
    3. Pressurize the EVAP system to 3.2 to 3.7 kPa (24 to 28 mmHg).
    4. Apply soapy water to the piping and connecting parts of the EVAP system.
    5. Look for areas where bubbles appear. This indicates the leak point.
    6. Repair or replace the leak point.

      HINT: 

      Disconnect the hose between the canister and the fuel tank from the canister. Block the canister side and conduct an inspection. In this way, the fuel tank can be excluded as an area suspected of causing fuel leaks.

    NEXT → See step   37 

  32. REPAIR OR REPLACE HARNESS OR CONNECTOR 

    NEXT → See step   37 

  33. REPLACE EVAP HOSE (INTAKE AIR SURGE TANK - PURGE VSV) 

    NEXT → See step   37 

  34. INSPECT INTAKE AIR SURGE TANK 
    1. Check that the EVAP purge port of the intake air surge tank is not clogged. If necessary, replace the intake air surge tank.

    NEXT → See step   37 

  35. REPLACE ECM

    NEXT → See step   37 

  36. REPAIR OR REPLACE PARTS OR COMPONENTS INDICATED BY OUTPUT DTCS 
    1. Repair the malfunctioning areas indicated by the DTCs that had been confirmed when the vehicle was brought in.

    NEXT → See step   37 

  37. PERFORM EVAP SYSTEM CHECK (AUTOMATIC MODE) 
    NOTE:
    • In the Evaporative System Check (Automatic Mode), the series of 5 Evaporative System Check steps is performed automatically. It takes a maximum of approximately 19 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 and making the leak check of the fuel tank unavailable.
    • Do not run the engine in this step.
    • When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing an Evaporative System Check, keep the temperature below 35°C (95°F).
    1. Clear the DTCs. Refer toDTC CHECK / CLEAR .
    2. On the Techstream, enter the following menus: Powertrain / Engine and ECT / Utility / Evaporative System Check / Automatic Mode.
    3. After the Evaporative System Check is completed, check for pending DTCs by entering the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.

      HINT: 

      If no pending DTC is found, the repair has been successfully completed.
