   DTC P0607 and P0136, P0137, P0138, P0156, P0157 or P0158 are output	A
   DTC P0607 is output	B

B → See step   3 

A: Go to next step 

1. Inspect the P0136, P0137, P0138, P0156, P0157 or P0158 flow chart.

   HINT: 

   • If P0136 or P0156 is output, troubleshoot for that DTC first. Refer to INSPECTION PROCEDURE . Then proceed to "INSPECT ECM".
   • If P0137or P0157 is output, troubleshoot for that DTC first. Refer to INSPECTION PROCEDURE . Then proceed to "INSPECT ECM".
   • If P0138 or P0158 is output, troubleshoot for that DTC first. Refer to INSPECTION PROCEDURE . Then proceed to "INSPECT ECM".
   • If DTC P0607 and P0136, P0137, P0138, P0156, P0157 or P0158 are output, the output voltage of the heated oxygen sensor may remain close to 0 V or become high (around 1 V or more).

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

   If any exhaust gas leaks are present, repair it and proceed to  4"PERFORM CONFIRMATION DRIVING PATTERN". If no exhaust gas leaks are present, proceed to  4"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: Go to next step 

1. Clear the DTC. Refer to DTC CHECK / CLEAR .
2. Connect the Techstream to the DLC3.
3. Warm up the engine until the engine coolant temperature becomes 75° (167°F) or more.
4. Perform the driving pattern.
