AIRFLOW METER (WITH INTAKE AIR THERMOSENSOR)
Inspection
1. Remove the airflow meter. (Refer to page F-109.)
2. Check the airflow meter body for cracks.
3. Verify that the measuring plate moves smoothly.
4. Move the measuring plate and check for resistance between
the terminals with an ohmmeter.

1. Disconnect the water thermosensor connector.
2. Remove the water thermosensor.
Inspection
1. Place the sensor in water with a thermometer and heat the
water gradually.
2. Measure resistance of the sensor with an ohmmeter.
3. If not as specified, replace the water thermosensor.
lnstallatlon
1. Install a new washer and the water thermosensor.
Tlghtening torque:
25-29 N.m (2.5-3.0 m-kg,
18-22 ft-lb)
2. Connect the water thermosensor connector.
3. Start the engine and check for coolant leakage.

PRE-INSPECTION
1. Check the tire inflations and set to the recommended pressure, if necessary.
2. Inspect the front wheel bearing play; replace the bearing if necessary.
3. inspect the wheel and tire runout.
4. Inspect the ball joints and steering linkage for any excessive looseness.
5. The vehicle must be on level ground and have no luggage or passenger load.
6. The difference in height between the left and right sides from the center of the wheel to the fender brim
must not exceed
10mm (0.39 in).
7. Shake the vehicle to check operation of the shock absorbers.
