1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ETC / Trouble Codes.
5. Read the DTCs.
   RESULT
   
   

   Result	Refer to
   P0607 and P0136, P0137 or P0138	A
   P0607	B

B → Refer to step   3 

A: Refer to next step 

1. Inspect the P0136, P0137 or P0138 flowchart.
   • If P0136 is output, troubleshoot for that DTC first. Refer to CONFIRMATION DRIVING PATTERN . Then Refer to "INSPECT ECM".
   • If P0137 is output, troubleshoot for that DTC first. Refer to CONFIRMATION DRIVING PATTERN . Then Refer to "INSPECT ECM".
   • If P0138 is output, troubleshoot for that DTC first. Refer to CONFIRMATION DRIVING PATTERN . Then Refer to "INSPECT ECM".

   HINT: 

   If P0607 and P0136, P0137 or P0138 are output, the output voltage of the heated oxygen sensor may remain close to 0 V or become high (around 1 V or more).

NEXT → Refer to step   6 

1. Allow the engine to idle and rev the engine.
2. Check for exhaust gas leak around the heated oxygen sensor.

   If any exhaust gas leaks are present, repair it and Refer to step "Perform Confirmation Driving Pattern". If no exhaust gas leaks are present, Refer to "Perform Confirmation Driving Pattern".

   HINT: 

   • If no exhaust gas leaks are present, a malfunction in the heated oxygen sensor circuit is suspected.
   • If any exhaust gas leaks are present around the heated oxygen sensor, noise appears in the output voltage of the heated oxygen sensor.

NEXT: Refer to next step

1. Clear DTCs. Refer to DTC CHECK / CLEAR .
2. Connect the Techstream to the DLC3.
3. Warm up the engine until the engine coolant temperature becomes 75 °C (167 °F) or more.
4. Perform the driving pattern.
   1. Accelerate the vehicle until 80 km/h (50 mph) and stop the vehicle.
   2. Drive the vehicle by 56 to 80 km/h (35 to 50 mph) for 5 minutes or more.
   WARNING:

   When performing the confirmation driving pattern, obey all speed limits and traffic laws.

5. Enter the following menus: Powertrain / Engine and ETC / Trouble Codes.
6. Read the DTCs.
