INSPECTION AND ADJUSTMENT


IDLE AIR VOLUME LEARNING : Special Repair Requirement

1.PRECONDITIONING
Make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.
- Battery voltage: More than 12.9V (At idle)
- Engine coolant temperature: 70 - 100�C (158 - 212�F)
- Selector lever: N position
- Vehicle speed: Stopped
- Transmission: Warmed-up (Drive vehicle for 10 minutes.)
Do you have CONSULT-III?
YES - GO TO 2.
NO - GO TO 4.
2.IDLE AIR VOLUME LEARNING
With CONSULT-III
1. Perform Throttle Valve Closed Position Learning. Ignition Timing".
Is the inspection result normal?
YES - INSPECTION END
NO - GO TO 6.
4.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. Lift up the vehicle.
2. Perform Throttle Valve Closed Position Learning. Ignition Timing".

CAUTION:
Never leave the selector lever in the N position for a long period of time. In the N position, the engine operates but electricity cannot be generated.
16. Shift the selector lever to P position.
- GO TO 5.
5.CHECK IDLE SPEED AND IGNITION TIMING
1. Depress the accelerator pedal and keep it.
2. Shift the selector lever to N position with engine running.
3. Check idle speed and ignition timing are within the specifications. [1][2]Idle Speed and [1][2]Ignition Timing.

CAUTION:
Never leave the selector lever in the N position for a long period of time. In the N position, the engine operates but electricity cannot be generated.
4. Shift the selector lever to P position.
Is the inspection result normal?
YES - INSPECTION END
NO - GO TO 6.
6.DETECT MALFUNCTIONING PART-I
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 7.
NO - Repair or replace malfunctioning part.
7.DETECT MALFUNCTIONING PART-II
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". Specification Value.
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.
- INSPECTION END
