5. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.

6. Repeat the following procedure quickly five times within 5 seconds.

-

Fully depress the accelerator pedal.

-

Fully release the accelerator pedal.

7. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops

blinking and turned ON.

8. Fully release the accelerator pedal within 3 seconds after the MIL turned ON.

CHECK IDLE SPEED AND IGNITION TIMING

Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifi-

cations. For specification, refer to 

EC-1258, "Idle Speed"

 and 

EC-1258, "Ignition Timing"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 5.

5.

DETECT MALFUNCTIONING PART

Check the following

• Check that throttle valve is fully closed.

• Check PCV valve operation.

• Check that downstream of throttle valve is free from air leakage.
Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Repair or replace malfunctioning part.

6.

DETECT MALFUNCTIONING PART

Engine component parts and their installation condition are questionable. Check and eliminate the cause of

the incident.

It is useful to perform “TROUBLE DIAGNOSIS - SPECIFICATION VALUE”. Refer to 

EC-785, "Description"

.

If any of the following conditions occur after the engine has started, eliminate the cause of the incident and

perform Idle Air Volume Learning all over again:

• Engine stalls.

• Erroneous idle.

.

CAUTION:

*: Must be performed “IDLE AIR VOLUME LEARNING” when electric throttle control actuator or ECM is

replaced. Refer to 

EC-758, "Description"

.

Work Procedure

5. Touch “START” and wait 20 seconds.
“CMPLT” displayed on CONSULT screen?

YES

>> INSPECTION END

NO

>> GO TO 4.

3.

AIR FUEL RATIO INITIAL LEARNING

 Without CONSULT

NOTE:

• It is better to count the time accurately with a clock.

• It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a mal-

function.

1. Perform “ACCELERATOR PEDAL RELEASED POSITION LEARNING”. Refer to 

EC-753, "Description"

.

2. Perform “THROTTLE VALVE CLOSED POSITION LEARNING”. Refer to 

EC-754, "Description"

.

3. Start engine and warm it up to normal operating temperature.

4. Turn ignition switch OFF and wait at least 10 seconds.

5. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.

6. Repeat the following procedure quickly five times within 5 seconds.
