      HINT: 

      • *1: A rapid decrease in engine speed may have been caused by an electrical malfunction in the shared wiring of all or multiple cylinders, an increase in load from external parts, etc. The engine speed is considered to have decreased rapidly if either of the following conditions applies.

        Otherwise, the engine speed is considered to have decreased slowly.

        (a) In the freeze frame data, the decrease in engine speed from #3 to #5 is 400 rpm or higher.

        (b) In the freeze frame data, the engine speed at #5 is 120 rpm or less.

      • If the vehicle speed is 5 km/h (3 mph) or less and the difference between the Engine Speed and SPD (NT) is 100 rpm or less, inspect the CVT. (Depending on the rate of vehicle deceleration, the engine speed may have decreased due to the CVT lock-up release being late.) (for CVT Models)
      • *2: When a DTC is stored, feedback compensation increases because the air fuel ratio is determined to be lean.
      • *3: When a DTC is stored, feedback compensation decreases because the air fuel ratio is determined to be rich.
      • *4: This item should be checked when DTC P1603 is output and is not necessary to check when only P1605 is output.

  5. CHECK INTAKE SYSTEM 
    1. Check for air leakage in the intake system [vacuum hose disconnection, cracks, damaged gaskets, etc.].

      Refer to ON-VEHICLE INSPECTION [08/2013 - ]

      HINT: 

      • If the accelerator pedal is released after racing the engine, the inspection is easier to perform because the vacuum inside the intake pipes increases and the air suction noise becomes louder.
      • If Short FT #1 and Long FT #1 are largely different from the normal values when idling (the intake air volume is small) and almost the same as the normal values when racing the engine (the intake air volume is high), air leakage may be present.

      OK

      There is no air suction.

      HINT: 

      Perform "Inspection After Repair" after repairing or replacing the intake system.

    1. Check for air leakage in the intake system [vacuum hose disconnection, cracks, damaged gaskets, etc.].

      Refer to ON-VEHICLE INSPECTION [08/2013 - ]

      HINT: 

      • If the accelerator pedal is released after racing the engine, the inspection is easier to perform because the vacuum inside the intake pipes increases and the air suction noise becomes louder.
      • If Short FT #1 and Long FT #1 are largely different from the normal values when idling (the intake air volume is small) and almost the same as the normal values when racing the engine (the intake air volume is high), air leakage may be present.

      OK

      There is no air leakage.
