SFI SYSTEM, Diagnostic DTC:P1604

INSPECTION PROCEDURE

1. Malfunction Recurrence and Inspection Areas

   
   

   1. Freeze frame data exists, but the malfunction (starting difficulty) has not reoccurred and the malfunction conditions are unknown.

      
      

      1. The engine speed recorded in the freeze frame data is 0 rpm (the engine does not crank).

         Tip:

         One of the following problems may be present: battery depletion, excess engine friction, a starter malfunction or a crankshaft position sensor malfunction.

         
         

         • If the battery voltage is less than 6 V during cranking, there is a high probability that engine friction is abnormal.

         • If the battery voltage drops to 5 V or less when starting the engine, the battery may be malfunctioning.

         • 

           If the battery voltage fluctuates while cranking the engine, it can be concluded that cranking is being performed. When the engine speed is 0 rpm, the crankshaft position sensor and/or ECM may be malfunctioning.

      2. All engine speeds recorded in the freeze frame data are between 100 and 250 rpm (the engine cranks but there is no combustion).

         Tip:

         If the engine speed is between 100 and 250 rpm (no initial combustion), there may be a wiring problem or a complete failure of an ignition or fuel system part.

         
         
         • 

           Due to an engine coolant temperature sensor malfunction, the fuel injection volume is extremely high or low and the engine may not be able to be started.

      3. The engine speed recorded in the freeze frame data is 250 rpm or higher (the initial combustion and starter turnoff timing is too late).

         Tip:

         If the engine speed is 250 rpm or higher (combustion occurs but the initial combustion and starter turnoff timing is too late), the fuel injection volume is often incorrect (too low or too high) and determining the cause of the malfunction is often difficult.

         
         

         • Due to an engine coolant temperature sensor malfunction, the fuel injection volume is extremely high or low and engine starting trouble may occur.

         • If Long FT is incorrect, there may be a fuel supply problem due to the injectors or fuel pump being clogged, etc.

         • 

           If the engine cranking speed is too high, compression loss may have occurred due to carbon interfering with the valve operation.

   2. When the malfunction (starting difficulty) can be reproduced, or malfunction conditions are known, confirm the following details of the problem symptom and inspect the systems listed below.

      
      

      1. Problem Symptoms

         
         

         1. The engine does not crank.

            Tip:

            The starter is normal if a noise that indicates the starter pinion gear is extending is heard. The battery may be fully depleted or there may be excess engine friction.

         2. The engine cranking speed is abnormal.

            Tip:

            If the engine cranking speed is too high (for example, 300 rpm or higher with no combustion), compression loss may have occurred because carbon interfered with valve operation, etc.

         3. There is no initial combustion.

            Tip:

            If there is no initial combustion, there is probably a wiring problem or an ignition or fuel system part malfunction.

         4. The engine stalls after starter turnoff.

            Tip:

            If the engine stalls after starter turnoff, the air-fuel ratio may be incorrect or the VVT may have a problem returning.

         5. The initial combustion and starter turnoff occur late.

            Tip:

            If the initial combustion and starter turnoff occur late, the fuel injection volume is probably incorrect (too low or too high).

            Tip:

            Causes of fuel system malfunctions according to conditions present at the time of the malfunction.

            
            

            • When 2 to 3 minutes have elapsed after stopping the engine: Fuel pressure loss due to the fuel pressure regulator failing to maintain the fuel pressure.

            • When 15 to 120 minutes have elapsed after stopping the engine: Problem with injector fuel seal.

            • When a long time has elapsed after stopping the engine: Fuel pressure regulator is stuck open.
