Система Снижения Токсичности Отработавших Газов Проверка Без Снятия С Автомобиля. Corolla Auris

Turn the ignition switch on (IG), and then check that the engine starts and runs at idle.

Connect the intelligent tester to the DLC3.

Start the engine, then run it at idle.

Turn the intelligent tester on.

Select "Powertrain / ENGINE / Active Test / Control the EGR Position" in Data List.

Warm up the engine.
The coolant temperature should be between 75°C (167°F) and 90°C (194°F).

Check the EGR position.

1. Check the MAF reading for the conditions shown in the table below when the EGR position is not 0% (EGR ON).
   

   Standard:

   Engine Condition	Active Test	MAF
   Idling	Active test not performed	3.6 to 7.2 g/s
   	Active test performed (EGR position 0%)	5.8 to 12.4 g/s

   УКАЗАНИЕ:

   1. If the MAF reading is out of the standard range in either condition (active test performed or active test not performed), replace the EGR valve.
      
   2. If the MAF reading is out of the standard range in both conditions (active test performed and active test not performed), check the intake air flow meter.
      
   If any defects are found, replace the intake air flow meter, and then check operation of the EGR valve.
   

2. Check the MAF reading for the conditions shown in the table below when the EGR position is 0% (EGR OFF).
   

   Standard:

   Engine Condition	Active Test	MAF
   Idling	Active test not performed	5.8 to 12.4 g/s
   	Active test performed (EGR position 100%)	2.1 to 3.8 g/s

   УКАЗАНИЕ:

   1. If the MAF reading is out of the standard range in either condition (active test performed or active test not performed), replace the EGR valve.
      
   2. If the MAF reading is out of the standard range in both conditions (active test performed and active test not performed), check the intake air flow meter.
      
   If any defects are found, replace the intake air flow meter, and then check operation of the EGR valve.
   

Check for cracks, leaks or damage.

1. Check the engine assembly to see if the portions indicated by the arrows have cracks, leaks or damage.
   

   ПРИМЕЧАНИЕ:

   1. Detachment or other problems with the engine oil dipstick, filler cap, PCV hose and other components may cause the engine to run improperly.
      
   2. Air suction caused by disconnections, looseness or cracks in the parts of the air induction system between the throttle body and cylinder head will cause engine failure or engine malfunctions.
      
   If any defects are found, replace the parts as necessary.
