   RESULT
   
   

   Result	Proceed to
   DTC P3190, P3191 and/or P3193 are output	A
   DTC P3190, P3191 and/or P3193, and other DTCs are output	B

   HINT: 

   If any other codes besides P3190, P3191 and/or P3193 are output, perform troubleshooting for those DTCs first.

B → See step   17 

A: Go to next step 

HINT: 

When an insufficient amount of fuel is added to the vehicle and when the hybrid control system will not engage because the DTCs P3190, P3191 and/or P3193 that are output regard the vehicle as out of fuel, continue refueling the vehicle until the fuel level warning light turns off.

NG → REFILL FUEL 

OK: Go to next step 

1. Check the intake system for vacuum leaks. Refer to ON-VEHICLE INSPECTION .

   OK

   No leaks in intake system.

NG → REPAIR OR REPLACE INTAKE SYSTEM 

OK: Go to next step 

OK

Unusual noise and vibration do not occur.

NG → REPAIR OR REPLACE MALFUNCTIONING PART 

OK: Go to next step 

1. Check the fuel pressure. Refer to ON-VEHICLE INSPECTION - Step 2 .

NG → See step   23 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT Trouble Codes / Freeze Frame Data.
5. Calculate the requested torque* and compare it with Actual Engine Torque.

   HINT: 

   *: The requested torque is calculated by putting "Requested Engine Torque" and "HV Target Engine Speed" from the freeze frame data into the following formula:

   Requested torque = Requested Engine Torque (kW) / HV Target Engine Speed (RPM) x 9554

   Standard

   Actual Engine Torque is 60% or more of the request torque.

NEXT: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Clear the DTC. Refer to DTC CHECK / CLEAR .
5. Turn the power switch off and wait for at least 30 seconds.
6. Turn the power switch on (IG) and turn the Techstream on.
7. Put the engine in inspection mode (maintenance mode). Refer to INSPECTION MODE PROCEDURE .
8. Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.
9. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
10. Read the pending DTCs.

    Result

    Result	Proceed to
    P3190, P3191 or P3193 is output	A
    DTC is not output	B

B → END 

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Put the engine in inspection mode (maintenance mode). Refer to INSPECTION MODE PROCEDURE .
5. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or more.

   HINT: 

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

6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the EGR Step Position.
7. Check the engine idling condition and MAP values in the Data List while performing the Active Test.

   HINT: 

   • Do not leave the EGR valve open for 10 seconds or more during the Active Test.
   • Be sure to return the EGR valve to step 0 when the Active Test is completed.
   • Do not open the EGR valve 30 steps or more during the Active Test.

   OK

   MAP and idling condition change in response to EGR step position.

   Standard

   -	EGR Step Position (Active Test)
   	0 Steps	0 to 30 Steps
   Idling condition	Steady idling	Idling changes from steady to rough idling or engine stalls
   MAP (Data List)	MAP value is 20 to 40 kPa (150 to 300 mmHg) (EGR valve is fully closed)	MAP value is at least +10 kPa (75 mmHg) higher than when EGR valve is fully closed

   HINT: 

   During Active Test, if the idling condition does not change in response to EGR step position, then there is probably a malfunction in the EGR valve.

   Result

   Result	Proceed to
   Outside of standard range	A
   Within standard range	B

B → See step   15 

A: Go to next step 

1. Remove the EGR valve assembly. Refer to REMOVAL .
2. Check if the EGR valve is stuck open.

   OK

   EGR valve is tightly closed.

NG → See step   22 

OK: Go to next step 

1. Replace the ECM. Refer to REMOVAL .

NEXT: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Clear the DTC. Refer to DTC CHECK / CLEAR .
5. Turn the power switch off and wait for 30 seconds.
6. Turn the power switch on (IG) and turn the Techstream on.
7. Put the engine in inspection mode (maintenance mode). Refer to INSPECTION MODE PROCEDURE .
8. Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.
