DTC P0607: Control Module Performance [08/2015 - 08/2019]: Procedure
- CHECK ANY OTHER DTCS OUTPUT
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menu: Powertrain / Engine and ECT / Trouble Codes.
- Read the DTC (Refer to DTC CHECK / CLEAR [08/2015 - 08/2019]
).RESULT
Result Proceed to P0607 and P0136, P0137, P0138, P0156, P0157 or P0158 are output A P0607 is output B
Result:
B
See step 3
Result:
A
See step 2
- INSPECT DTC (P0136, P0137, P0138, P0156, P0157 OR P0158)
- Inspect the P0136, P0137, P0138, P0156, P0157 or P0158 flowchart.
HINT:
- If P0136 or P0156 is output, troubleshoot for that DTC first. Refer to
Then proceed to "INSPECT ECM".
- If P0137 or P0157 is output, troubleshoot for that DTC first. Refer to
Then proceed to "INSPECT ECM".
- If P0138 or P0158 is output, troubleshoot for that DTC first. Refer to
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).
- If P0136 or P0156 is output, troubleshoot for that DTC first. Refer to
Result:
NEXT
See step 6
- Inspect the P0136, P0137, P0138, P0156, P0157 or P0158 flowchart.
- CHECK FOR EXHAUST GAS LEAK
- Allow the engine to idle and rev the engine.
- Check for exhaust gas leaks around the heated oxygen sensor.
If any exhaust gas leaks are present, repair it and proceed to "PERFORM CONFIRMATION DRIVING PATTERN". If no exhaust gas leaks are present proceed 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.
- Perform "Inspection After Repair" after repairing or replacing the exhaust system (Refer to INITIALIZATION [08/2015 - 08/2019] ).

See step 4
- PERFORM CONFIRMATION DRIVING PATTERN
- Clear DTC (Refer to DTC CHECK / CLEAR [08/2015 - 08/2019] ).
- Connect the Techstream to the DLC3.
- Start the engine.
- Warm up the engine until the engine coolant temperature becomes 75°C (167°F) or more.
- Perform the drive pattern.
- Accelerate the vehicle to 80 km/h (50 mph) and stop the vehicle.
- Drive the vehicle between 60 and 80 km/h (35 and 50 mph) for 5 minutes.
- Enter the following menu: Powertrain / Engine and ECT / Trouble Codes.
- Read the DTCs.RESULT
Result Proceed to P0607 and P0136, P0137, P0138, P0156, P0157 or P0158 are output A Only P0607 B No DTC output C
