Code No. P061A: Torque Monitoring

FUNCTION

Compares the actual torque signal computed from a manifold absolute pressure sensor signal with the driver demand torque signal computed from an accelerator pedal position sensor signal.

TROUBLE JUDGEMENT

Check Conditions

Engine speed is more than 500 r/min.
Inlet manifold pipe pressure is more than 25 kPa.

Judgement Criterion

The difference between the actual torque signal and the demand torque signal exceeds the specified value.

FAIL-SAFE AND BACKUP FUNCTION

Throttle opening degree position is in default position.

PROBABLE CAUSES

Failed throttle valve control servo
Harness damage in throttle valve control servo circuit or loose connector contact.
Air drawn in from inlet hose and inlet manifold
Failed engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis code

Q. Is any other diagnosis code than P061A stored?

	Inspection chart for diagnosis code (Refer to ).

	Go to Step 2.

STEP 2. M.U.T.-III data list

Refer to Data List Reference Table .

Item 8: Manifold absolute pressure sensor
Item 11: Accelerator pedal position sensor (main)
Item 12: Accelerator pedal position sensor (sub)

Q. Are the check results normal?

	Go to Step 3.

	Perform the diagnosis code classified check procedure for the sensor that has shown an abnormal data value (Refer to Inspection Chart for Diagnosis Code ).

STEP 3. Check air intake from inlet hose and inlet manifold.

Q. Is the check result normal?

	Go to Step 4.

	Repair.

STEP 4. Check throttle valve control servo itself.

Check throttle valve control servo (Refer to ).

Q. Is the check result normal?

	Go to Step 5.

	Replace the throttle body assembly.

STEP 5. Check of damage in ETV- line between electronic-controlled throttle valve connector and engine-ECU connector.

Q. Is the check result normal?

	Go to Step 6.

	Repair the connector(s) or wiring harness.

STEP 6. Check of damage in ETV+ line between electronic-controlled throttle valve connector and engine-ECU connector.

Q. Is the check result normal?

	Go to Step 7.

	Repair the connector(s) or wiring harness.

STEP 7. M.U.T.-III diagnosis code

Reconfirmation of diagnosis code.

Q. Is diagnosis code stored?

	Replace the engine-ECU.

	Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
