2AZ-FXE ENGINE CONTROL: SFI SYSTEM: P0607: Control Module Performance
P0607 - Control Module Performance

MONITOR DESCRIPTION

The hybrid vehicle control ECU continuously monitors its internal processors (CPUs) and heated oxygen sensor transistors. This self-check ensures that the hybrid vehicle control ECU is functioning properly.

TYPICAL MALFUNCTION THRESHOLDS





CONFIRMATION DRIVING PATTERN





- Stop the engine for 30 minutes or more [A].

- Connect the Techstream to the DLC3.

- Turn the power switch on (IG) and turn the Techstream on [B].

- Clear the DTCs DTC Check / Clear.

- Turn the power switch off and wait for at least 30 seconds.

- Turn the power switch on (IG) and turn the Techstream on [C].

- Put the engine in inspection mode Component Tests and General Diagnostics.

- Start the engine, and wait 2 minutes [D].

- Warm up the engine until the engine coolant temperature is 75°C (167°F) or higher [E].

- Idle the engine for 1 minute [F].

- Accelerate the vehicle to 50 mph (80 km/h) and stop the vehicle [G].

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

- Drive the vehicle at 35 to 50 mph (56 to 80 km/h) for 5 minutes or more [H].

- Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

- Read the DTC [I].

HINT
- If a DTC is output, the system is malfunctioning.
- If a DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

- Input the DTC: P0607, P0136, P0137 or P0138.

- Check the DTC judgment result.





HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or UNKNOWN, perform steps [E] through [I] again.
INSPECTION PROCEDURE

PROCEDURE

1. CHECK ANY OTHER DTCS OUTPUT

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(e) Read the DTCs.

Result:





B -- CHECK FOR EXHAUST GAS LEAK
A -- Continue to next step.

2. INSPECT DTC (P0136, P0137 OR P0138)

(a) Inspect the P0136, P0137 or P0138 flowchart.

HINT
- If P0136 is output, troubleshoot for that DTC first P0136. Then proceed to "INSPECT HYBRID VEHICLE CONTROL ECU".
- If P0137 is output, troubleshoot for that DTC first P0136. Then proceed to "INSPECT HYBRID VEHICLE CONTROL ECU".
- If P0138 is output, troubleshoot for that DTC first P0136. Then proceed to "INSPECT HYBRID VEHICLE CONTROL ECU".
- If DTC 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 -- INSPECT HYBRID VEHICLE CONTROL ECU

3. CHECK FOR EXHAUST GAS LEAK

(a) Put the engine in inspection mode Component Tests and General Diagnostics.

(b) Allow the engine to idle and rev the engine.

(c) Check for exhaust gas leaks around the heated oxygen sensor.

If any exhaust gas leaks are present, repair them 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.
NEXT -- Continue to next step.

4. PERFORM CONFIRMATION DRIVING PATTERN





(a) Clear the DTC DTC Check / Clear.

(b) Connect the Techstream to the DLC3.

(c) Turn the power switch on (IG) and turn the Techstream on.

(d) Put the engine in inspection mode Component Tests and General Diagnostics.

(e) Start the engine.

(f) Warm up the engine until the engine coolant temperature becomes 75°C (167°F) or more.

(g) Perform the driving pattern.

(1) Accelerate the vehicle to 50 mph (80 km/h) and stop the vehicle.

(2) Drive the vehicle between 38 and 50 mph (60 and 80 km/h) for 5 minutes.

(h) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(i) Read the DTCs.

Result:





C -- INSPECT HYBRID VEHICLE CONTROL ECU

B -- REPLACE HYBRID VEHICLE CONTROL ECU Removal
A -- Continue to next step.

5. INSPECT DTC (P0136, P0137 OR P0138)

(a) Inspect the P0136, P0137 or P0138 flowchart.

HINT
- If P0136 is output, troubleshoot for that DTC first P0136. Then proceed to "INSPECT HYBRID VEHICLE CONTROL ECU".
- If P0137 is output, troubleshoot for that DTC first P0136. Then proceed to "INSPECT HYBRID VEHICLE CONTROL ECU".
- If P0138 is output, troubleshoot for that DTC first P0136. Then proceed to "INSPECT HYBRID VEHICLE CONTROL ECU".
- If DTC 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 -- Continue to next step.

6. INSPECT HYBRID VEHICLE CONTROL ECU

(a) Clear the DTC DTC Check / Clear.

(b) Stop the engine and wait for 30 minutes.

(c) Connect the Techstream to the DLC3.

(d) Turn the power switch on (IG) and turn the Techstream on.

(e) Put the engine in inspection mode Component Tests and General Diagnostics.

(f) Start the engine and allow it to idle for 2 minutes.

(g) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(h) Check the DTCs.

Result:





B -- REPLACE HYBRID VEHICLE CONTROL ECU Removal

A -- END
