Otherwise, the engine speed is considered to have decreased slowly. In the freeze frame data, the decrease in engine speed from #3 to #5 is 400 rpm or more. In the freeze frame data, the engine speed at #5 is 120 rpm or less. If the vehicle speed is 30 km/h or less and the difference between Engine Speed and SPD (NT) is 100 rpm or less, inspect the automatic transmission. (Depending on the rate of vehicle deceleration, the engine speed may have decreased due to the A/T lock-up release being late.) *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 AIR INDUCTION SYSTEM Check for air leakage in the intake system [vacuum hose disconnection, cracks, damaged gaskets, etc.]. Refer to «ON-VEHICLE INSPECTION [05/2013 - ]»(ref-615245-S19604784762014050900000) . 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 and Long FT 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. Perform "Inspection After Repair" after repairing or replacing the air induction system. Refer to «INITIALIZATION [05/2013 - ]»(ref-615120-S07565023022014050900000) . OK There is no air leakage.

Otherwise, the engine speed is considered to have decreased slowly. In the freeze frame data, the decrease in engine speed from #3 to #5 is 400 rpm or more.

If the vehicle speed is 30 km/h or less and the difference between Engine Speed and SPD (NT) is 100 rpm or less, inspect the automatic transmission. (Depending on the rate of vehicle deceleration, the engine speed may have decreased due to the A/T lock-up release being late.) *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.
