INSPECTION AND ADJUSTMENT
THROTTLE VALVE CLOSED POSITION LEARNING
THROTTLE VALVE CLOSED POSITION LEARNING : DescriptionINFOID:0000000003856455
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by
monitoring the throttle position sensor output signal. It must be performed each time harness connector of
electric throttle control actuator or ECM is disconnected.
THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement
INFOID:0000000003856456
1.START
1. Check that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
Check that throttle valve moves during above 10 seconds by confirming the operating sound.

IDLE AIR VOLUME LEARNING
IDLE AIR VOLUME LEARNING : DescriptionINFOID:0000000003856457
Idle Air Volume Learning is a function of ECM to learn the idle air volume that keeps engine idle speed within
the specific range. It must be performed under the following conditions:
 Each time electric throttle control actuator or ECM is replaced.
 Idle speed or ignition timing is out of specification.
IDLE AIR VOLUME LEARNING : Special Repair RequirementINFOID:0000000003856458
1.PRECONDITIONING
Before performing Idle Air Volume Learning, check 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 12.9 V (At idle)
 Engine coolant temperature: 70 - 100°C (158 - 212°F)
 Selector lever: P or N
 Electric load switch: OFF
(Air conditioner, head lamp, rear window defogger)
-For vehicle equipped with daytime light systems, perform one of the following procedures before
starting engine not to illuminate headlamps.
 Apply parking brake
 Set lighting switch to the 1st position
 Steering wheel: Neutral (Straight-ahead position)
 Vehicle speed: Stopped
 Transmission: Warmed-up
- With CONSULT-III: Drive vehicle until “ATF TEMP SEN” in “DATA MONITOR” mode of “CVT” system indi-
cates less than 0.9 V.
- Without CONSULT-III: Drive vehicle for 10 minutes.
Will CONSULT-III be used?
YES >> GO TO 2.
NO >> GO TO 3.
2.PERFORM IDLE AIR VOLUME LEARNING
With CONSULT-III
1. Perform EC-15, "
ACCELERATOR PEDAL RELEASED POSITION LEARNING : Special Repair Require-
ment".
2. Perform EC-16, "
THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement".
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode.
5. Touch “START” and wait 20 seconds.

ELECTRONIC CONTROLLED ENGINE MOUNT
DescriptionINFOID:0000000003856835
The electronic controlled engine mount control solenoid valve controls the intake manifold vacuum signal for
electronic controlled engine mount. The electronic controlled engine mount control solenoid valve is moved by
ON/OFF signal from the ECM. When the solenoid is OFF, the vacuum signal from the intake manifold is cut.
When the solenoid is ON, the intake manifold vacuum signal is sent to the electronic controlled engine mount.
Component Function CheckINFOID:0000000003856836
1.CHECK OVERALL FUNCTION
1. Start engine and warm it up to normal operating temperature.
2. Selector level position is D while depressing the brake pedal and parking brake pedal.
3. Disconnect electronic controlled engine mount control solenoid valve harness connector.
4. Check that body vibration increases compared to the condition of step 2 above (with vehicle stopped).
Is the inspection result normal?
YES >> INSPECTION END
NO >>EC-331, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003856837

Is the inspection result normal?
YES >> GO TO 7.
NO >> GO TO 2.
2.CHECK VACUUM HOSES AND VACUUM GALLERY
1. Turn ignition switch OFF.
2. Check vacuum hoses and vacuum gallery for clogging, cracks or improper connection. Refer to EC-68,

FUEL TANK
4. Remove rear parking brake cables. Refer to PB-5, "Exploded View".
5. Disconnect fuel filler hose, and vent hose at the position shown
in the figure.
6. Disconnect EVAP hose at EVAP canister side.
7. Support the lower part of fuel tank (1) with transmission jack (A).
CAUTION:
Support the position that fuel tank mounting bands never
engage.
8. Remove fuel tank mounting bands.
9. Supporting with hands, descend transmission jack carefully, and remove fuel tank.
CAUTION:
 Check that all connection points have been disconnected.
 Confirm there is no interference with vehicle.
10. Remove fuel filler tube, as necessary.
INSTALLATION
Note the following, and install in the reverse order of removal.
 Surely clamp fuel hoses and insert hose to the length below.
 Be sure hose clamp is not placed on swelled area of fuel tube.
 Tighten fuel filler hose clamp so that the remaining length of screw thread becomes to the following.
 To connect quick connector, refer to FL-5, "
Removal and Installation".

INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leakage.
1. Turn ignition switch “ON” (with engine stopped), and check connections for leakage by applying fuel pres-
sure to fuel piping.
2. Start engine and rev it up and check there are no fuel leakage at the fuel system tube and hose connec-
tions.
