3.IDLE AIR VOLUME LEARNING
Without CONSULT-III
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 malfunction.
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-693, "
ACCELERATOR PEDAL
RELEASED POSITION LEARNING : Special Repair Requirement".
2. Perform Throttle Valve Closed Position Learning. Refer to EC-694, "
THROTTLE VALVE CLOSED POSI-
TION LEARNING : Special Repair Requirement".
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.
- 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 MI stops
blinking and turned ON.
8. Fully release the accelerator pedal within 3 seconds after the MI turned ON.
9. Start engine and let it idle.
10. Wait 20 seconds.
>> GO TO 4
4.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-1038, "
Idle Speed" and EC-1038, "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-781, "
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.

This describes how to erase the mixture ratio self-learning value. For the actual procedure, follow the instruc-
tions in “Diagnosis Procedure”.
MIXTURE RATIO SELF-LEARNING VALUE CLEAR : Special Repair Requirement
INFOID:0000000001161718
1.START
With CONSULT-III
1. Start engine and warm it up to normal operating temperature.
2. Select “SELF-LEARNING CONT” in “WORK SUPPORT” mode with CONSULT-III.
3. Clear mixture ratio self-learning value by touching “CLEAR”.
With GST
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF.
3. Disconnect mass air flow sensor harness connector.
4. Restart engine and let it idle for at least 5 seconds.
5. Stop engine and reconnect mass air flow sensor harness connector.
6. Select Service $03 with GST. Make sure DTC P0102 is detected.
7. Select Service $04 with GST to erase the DTC P0102.
