RELATED DTCS

NOTICE:

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

DESCRIPTION

HINT:

The canister pressure sensor, the leak detection pump and the vent valve are built into the canister pump module.

NOTICE:

In the EVAP system of this vehicle, turning ON the vent valve does not seal off the EVAP system. To check for leaks in the EVAP system, disconnect the air inlet vent hose and apply pressure from atmospheric side of the canister.

HINT:

*: If the engine coolant temperature is not below 35°C (95°F) 5 hours after the ignition switch is turned off, the monitor check starts 2 hours later. If it is still not below 35°C (95°F) 7 hours after the ignition switch is turned off, the monitor check starts 2.5 hours later.

1. The 1st monitor
   While the engine is running and the purge VSV (Vacuum Switching Valve) is on (open), the ECM monitors the purge flow by measuring the EVAP pressure change. If negative pressure is not created, the ECM begins the 2nd monitor.
   
2. The 2nd monitor
   The vent valve is turned ON (closed) and the EVAP pressure is then measured. If the variation in the pressure is less than 0.15 kPa(gauge) [1.13 mmHg(gauge)], the ECM interprets this as the purge VSV being stuck closed, and illuminates the MIL and stores DTC P0441 (2 trip detection logic).
   

1. Atmospheric pressure check:
   
1. In order to ensure reliable malfunction detection, the variation between the atmospheric pressures, before and after of the purge flow monitor, is measured by the ECM.

INSPECTION PROCEDURE

NOTICE:

1. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
   
2. The Techstream is required to conduct the following diagnostic troubleshooting procedure.
   

HINT:

1. Using the Techstream monitor results enables the EVAP (Evaporative Emission) system to be confirmed.
   
2. Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
   

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 stored, the malfunctioning area can be determined using the table below.
   

   
   
   
   

   NOTICE:

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

NOTICE:

1. The Evaporative System Check (Automatic Mode) consists of 6 steps performed automatically by the Techstream. It takes a maximum of approximately 24 minutes.
   
2. 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.
   
3. Do not run the engine during this operation.
   
4. 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. Connect the Techstream to the DLC3.
   

2. Turn the ignition switch to ON.
   

3. Turn the Techstream on.
   

4. Clear the DTCs (Click here).

6. 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 DTCs are displayed, perform the Confirmation Driving Pattern. After this confirmation, check for pending DTCs. If no DTCs are displayed, the EVAP system is normal.

If liquids are present, check for disconnections and/or cracks in the following: 1) the pipe from the air inlet port to the canister pump module; 2) the canister filter; and 3) the fuel tank vent hose.
      
   2. Check for filter blockage in the canister filter. if the canister filter has blockages, replace the canister filter.

NOTICE:

1. The Evaporative System Check (Automatic Mode) consists of 6 steps performed automatically by the Techstream. It takes a maximum of approximately 24 minutes.
   
2. 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.
   
3. Do not run the engine in this step.
   
4. 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 fuel temperature below 35°C (95°F).
   

1. Connect the Techstream to the DLC3.
   

2. Turn the ignition switch to ON.
   

3. Turn the Techstream on.
   

4. Clear the DTCs (Click here).
   

5. Enter the following menus: Powertrain / Engine and ECT / Utility / Evaporative System Check / Automatic Mode.
   

6. After the Evaporative System Check is completed, check for pending DTCs by entering the following menus: Powertrain / Engine and ECT / Trouble Codes.

CONFIRMATION DRIVING PATTERN

HINT:

After a repair, check Monitor Status by performing the Key-Off Monitor Confirmation and Purge Flow Monitor Confirmation described below.

1. Preconditions
   The monitor will not run unless:
   

   1. The vehicle has been driven for 10 minutes or more (in a city area or on a freeway).
      
   2. The fuel tank is less than 90% full.
      
   3. The altitude is less than 7875 ft. (2400 m).
      
   4. The engine coolant temperature is between 4.4°C and 35°C (40°F and 95°F).
      
   5. The intake air temperature is between 4.4°C and 35°C (40°F and 95°F).
      
   6. The vehicle remains stationary (the vehicle speed is 0 km/h [0 mph]).
      

2. Monitor Conditions
   

   1. Allow the engine to idle for at least 5 minutes.
      
   2. Turn the ignition switch off and wait for 6 hours (8 or 10.5 hours).
      

      HINT:

      Do not start the engine until checking Monitor Status. If the engine is started, the steps described above must be repeated.

3. Monitor Status
   

   1. Connect the Techstream to the DLC3.
      
   2. Turn the ignition switch to ON.
      
   3. Turn the Techstream on.
      
   4. Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor.
      
   5. Check the Monitor Status displayed on the Techstream.
      

      HINT:

      If Incomplete is displayed, the monitor did not complete. Make sure that the preconditions have been met, and perform the Monitor Conditions again.

HINT:

Perform this monitor confirmation after the Key-Off Monitor Confirmation shows Complete.

   3. The intake air temperature is 4.4°C (40°F) or higher.
      

2. Monitor Conditions
   

   1. Release the pressure from the fuel tank by removing and reinstalling the fuel cap.
      
   2. Warm the engine up until the engine coolant temperature reaches more than 75°C (167°F).
      
   3. Increase the engine speed to 3000 rpm once.
      
   4. Allow the engine to idle and turn the A/C switch on for 1 minute.
      

3. Monitor Status
   

   1. Turn the ignition switch off (if ON or if the engine is running).
      
   2. Connect the Techstream to the DLC3.
      
   3. Turn the ignition switch to ON.
      
   4. Turn the Techstream on.
      
   5. Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor.
      
   6. Check the Monitor Status displayed on the Techstream.
