A: Go to next step 

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

   HINT: 

   • If P0136 or P0156is output, troubleshoot for that DTC first. Refer to DTC P0136: Oxygen Sensor Circuit Malfunction (Bank 1 Sensor 2); DTC P0137: Oxygen Sensor Circuit Low Voltage (Bank 1 Sensor 2); DTC P0138: Oxygen Sensor Circuit High Voltage (Bank 1 Sensor 2); DTC P0139: Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 2); DTC P0156: Oxygen Sensor Circuit Malfunction (Bank 2 Sensor 2); DTC P0157: Oxygen Sensor Circuit Low Voltage (Bank 2 Sensor 2); DTC P0158: Oxygen Sensor Circuit High Voltage (Bank 2 Sensor 2); DTC P0159: Oxygen Sensor Circuit Slow Response (Bank 2 Sensor 2) . Then proceed to "INSPECT ECM".
   • If P0137 or P0157 is output, troubleshoot for that DTC first. Refer to DTC P0136: Oxygen Sensor Circuit Malfunction (Bank 1 Sensor 2); DTC P0137: Oxygen Sensor Circuit Low Voltage (Bank 1 Sensor 2); DTC P0138: Oxygen Sensor Circuit High Voltage (Bank 1 Sensor 2); DTC P0139: Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 2); DTC P0156: Oxygen Sensor Circuit Malfunction (Bank 2 Sensor 2); DTC P0157: Oxygen Sensor Circuit Low Voltage (Bank 2 Sensor 2); DTC P0158: Oxygen Sensor Circuit High Voltage (Bank 2 Sensor 2); DTC P0159: Oxygen Sensor Circuit Slow Response (Bank 2 Sensor 2) . Then proceed to "INSPECT ECM".
   • If P0138 or P0158 is output, troubleshoot for that DTC first. Refer to DTC P0136: Oxygen Sensor Circuit Malfunction (Bank 1 Sensor 2); DTC P0137: Oxygen Sensor Circuit Low Voltage (Bank 1 Sensor 2); DTC P0138: Oxygen Sensor Circuit High Voltage (Bank 1 Sensor 2); DTC P0139: Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 2); DTC P0156: Oxygen Sensor Circuit Malfunction (Bank 2 Sensor 2); DTC P0157: Oxygen Sensor Circuit Low Voltage (Bank 2 Sensor 2); DTC P0158: Oxygen Sensor Circuit High Voltage (Bank 2 Sensor 2); DTC P0159: Oxygen Sensor Circuit Slow Response (Bank 2 Sensor 2) . 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 Step  4.

   • 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 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°(167°F) or more.
4. Perform the driving pattern.

   1. Accelerate the vehicle until 50 mph (80 km/h) and stop the vehicle.
   2. Drive the vehicle between 35 to 50 mph (56 to 80 km/h) for 5 minutes.
5. Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.
6. Read the pending DTCs.
