1. Remove the following parts.
 Battery ground cable
 Engine undercover
 RH front wheel
2. Remove fender protector RH. Refer to EXT-22, "
Removal and Installation".
3. Drain engine coolant. Refer to CO-58, "
Draining".
CAUTION:
Perform when engine is cold.
4. Remove drive belt. Refer to EM-263, "
Removal and Installation".
5. Remove timing belt and inner cover. Refer to EM-291, "
Removal and Installation".

 Place a thread so that it is caught in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.
(The example shows the thermostat.)
 The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
 Continue heating. Check the full-open lift amount.
 After checking the full-open lift amount, lower the water tempera-
ture and check the valve closing temperature.
 If the measured value is out of the standard value or unusual valve
seating condition is found, replace water inlet and thermostat
assembly.
INSPECTION AFTER INSTALLATION
 Check for engine coolant leaks using suitable tools. Refer to CO-58, "Inspection".

BASIC INSPECTION : Special Repair RequirementINFOID:0000000001161123
1.INSPECTION START
1. Check service records for any recent repairs that may indicate a related malfunction, or a current need for
scheduled maintenance.
2. Open engine hood and check the following:
- Harness connectors for improper connections
- Wiring harness for improper connections, pinches and cut
- Vacuum hoses for splits, kinks and improper connections
- Hoses and ducts for leaks
- Air cleaner clogging
- Gasket
3. Confirm that electrical or mechanical loads are not applied.
- Headlamp switch is OFF.
- Air conditioner switch is OFF.
- Rear window defogger switch is OFF.
- Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature
indicator points the middle of gauge.
Ensure engine stays below 1,000 rpm.
5. Run engine at about 2,000 rpm for about 2 minutes under no
load.
6. Make sure that no DTC is displayed with CONSULT-III or GST.
Is any DTC detected?
YES >> GO TO 2.
NO >> GO TO 3.
2.REPAIR OR REPLACE
Repair or replace components as necessary according to corresponding Diagnostic Procedure.
>> GO TO 3
3.CHECK TARGET IDLE SPEED
1. Run engine at about 2,000 rpm for about 2 minutes under no load.

THROTTLE VALVE CLOSED POSITION LEARNING
THROTTLE VALVE CLOSED POSITION LEARNING : DescriptionINFOID:0000000001161132
Throttle Valve Closed Position Learning is a function of ECM 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 connec-
tor of electric throttle control actuator or ECM is disconnected.
THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement
INFOID:0000000001161133
1.START
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.

IDLE AIR VOLUME LEARNING
IDLE AIR VOLUME LEARNING : DescriptionINFOID:0000000001161134
Idle Air Volume Learning is a function of ECM to learn the idle air volume that keeps each engine idle speed
within the specific range. It must be performed under any of 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:0000000001161135
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)
 Park/neutral position switch: ON
 Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, set lighting switch to the 1st position to light only
small lamps.
 Steering wheel: Neutral (Straight-ahead position)
 Vehicle speed: Stopped
 Transmission: Warmed-up
- For A/T models with CONSULT-III
 Drive vehicle until “ATF TEMP SE 1” in “DATA MONITOR” mode of “A/T” system indicates less than 0.9V.
- For A/T models without CONSULT-III and M/T models.
 Drive vehicle for 10 minutes
Do you have CONSULT-III?
YES >> GO TO 2.
