СИСТЕМА SFI, Diagnostic DTC:P1603, P1605

DESCRIPTION

After starting the engine, this DTC is stored when the engine stops without the engine switch being operated.

Using the GTS, the conditions present when the DTC was stored can be confirmed by referring to the freeze frame data. Freeze frame data records engine conditions when a malfunction occurs. This information can be useful when troubleshooting.

It is necessary to check if the vehicle has ran out of fuel before performing troubleshooting, as this DTC is also stored when the engine stalls due to running out of fuel.

This DTC is stored if the engine speed drops below the set speed.

Using the GTS, the conditions present when the DTC was stored can be confirmed by referring to the freeze frame data. Freeze frame data records engine conditions when a malfunction occurs. This information can be useful when troubleshooting.

It is necessary to check if the vehicle ran out of fuel before performing troubleshooting, as this DTC is also stored when idling is unstable due to running out of fuel.

      Table 4. Result

      Problem Symptom	Freeze Frame Data Item for DTC P1605			Suspected Area	Proceed to
      	Closed Throttle Position SW	Engine Speed	Total of Short FT and Long FT
      When idling or decelerating, engine speed slowly decreases and engine stalls	All 5 sets of freeze frame data are ON	Decreases slowly*1	All 5 sets of freeze frame data are +15% or more*2	Air suction Sensor malfunction (value from sensor too lean) Fuel supply problem	A
      			At least 1 of the 5 sets of freeze frame data is -15% or less*3	Sensor malfunction (value from sensor too rich)	B
      			All 5 sets of freeze frame data are from -15% to +15%	Intake air volume insufficient Ignition timing incorrect	C
      When idling or decelerating, engine speed rapidly decreases and engine stalls		Decreases rapidly*1	-	Injection stoppage, ignition stoppage Load from external parts	D
      When accelerating or driving at constant speed, engine stalls*4	At least one is OFF	-	-	Sensor malfunction Injection stoppage, ignition stoppage Fuel supply problem	E

      Tip:
      

      • *1: A rapid decrease in engine speed may be caused by an electrical fault in the shared wiring of all or a number of 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.

      • 
        

        1. In the freeze frame data, the decrease in engine speed from #3 to #5 is 400 rpm or more.

        2. 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.

   CHECK INTAKE SYSTEM

   
   

   1. Check for air leakage in the intake system [due to vacuum hose disconnection, cracks, damaged gaskets, etc.] (Click here).

      Tip:
      

      • 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.

      OK
      There is no air leakage.

   CHECK PURGE VSV

   
   
   1. 

      Disconnect the purge hose (on the canister side) of the purge VSV.

   2. Start the engine.

   3. Idle the engine.

   4. Disconnect the connector of the purge VSV.

   5. Check if air flows through the purge VSV.

      OK
      Air does not flow.

   6. Connect the connector of the purge VSV.

   7. Connect the purge hose of the purge VSV.

   1. Connect the GTS to the DLC3.

   2. Turn the engine switch on (IG).

   3. Using the GTS, confirm the vehicle conditions recorded in the freeze frame data which were present when the DTC was stored (Click here).

      Tip:
      

      • *1: If the mass air flow meter is malfunctioning and incorrectly measures the pressure to be less than the actual intake manifold pressure, the freeze frame data will show a low engine load value.

      • *2: If the air fuel ratio sensor is malfunctioning and constantly outputs a value indicating the air-fuel ratio is lean, the actual air-fuel ratio will become rich and the engine may stall.

       Tip:
       

       • 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.

    CHECK MASS AIR FLOW METER ASSEMBLY

    
    

    1. Remove the mass air flow meter assembly.

    2. Check for foreign matter in the airflow passage of the mass air flow meter.

       Table 44. Result

       Result	Proceed to
       Visible foreign matter is present	A
       Visible foreign matter is not present	B

    3. Install the mass air flow meter.

       Tip:

       Even if the results are normal, the mass air flow meter may have been malfunctioning. Continue this inspection procedure until step 54, and if there are no problems with other parts, replace the mass air flow meter assembly (refer to step 55).

    CHECK HARNESS AND CONNECTOR (ECM - MASS AIR FLOW METER)

    
    

    1. Check the harnesses and connectors, referring to DTC P0102 inspection procedure (Click here).

       Tip:
       

       • Jiggle the wire harness and connector to increase the likelihood of detecting malfunctions that do not always occur.

       • Make sure there is not an excessive amount of force applied to the wire harness.

    PERFORM DRIVE TEST

    
    

    1. Connect the GTS to the DLC3.

    2. Start the engine and warm it up until the engine coolant temperature stabilizes.

       Tip:

       The A/C switch and all accessory switches should be off.

    3. Idle the engine.

    4. Using the GTS, read the value of Calculate Load in the Data List.

       Table 45. Standard

       Data List	Specified Condition
       Calculate Load	90 to 110% of the current value of the vehicle

    CHECK TERMINAL VOLTAGE (FUEL INJECTOR POWER SOURCE)

    
    

    1. Disconnect the fuel injector connector.

    2. Turn the engine switch on (IG).

    3. Measure the voltage according to the value(s) in the table below.

       Standard Voltage

       Cylinder Tester Connection Switch Condition Specified Condition No. 1 a5-2 - Body ground Engine switch on (IG) 11 to 14 V No. 2 a1-2 - Body ground Engine switch on (IG) 11 to 14 V No. 3 a6-2 - Body ground Engine switch on (IG) 11 to 14 V No. 4 a2-2 - Body ground Engine switch on (IG) 11 to 14 V No. 5 a7-2 - Body ground Engine switch on (IG) 11 to 14 V No. 6 a3-2 - Body ground Engine switch on (IG) 11 to 14 V No. 7 a8-2 - Body ground Engine switch on (IG) 11 to 14 V No. 8 a4-2 - Body ground Engine switch on (IG) 11 to 14 V

       Tip:
       

       • Jiggle the wire harness and connector to increase the likelihood of detecting malfunctions that do not always occur.

       • Make sure there is not an excessive amount of force applied to the wire harness.

       • A rapid decrease in engine speed may have been caused by a malfunction in all or multiple cylinders. There may be an electrical malfunction in the wiring shared by all the cylinders.
