Removal
Preparation:
Disconnect negative (-) battery cable.
1. Remove the rear side ATF cooler pipe from the
transmission elbow.
2. Disconnect neutral start switch connector.
3. Unstake the lock washer, and then remove the shaft
nut (3).
4. Remove the neutral start switch.
Installation
To install, follow the removal steps in the reverse order,
noting the following points;
Torque:
Nut – 7 N・・・・m (0.7 kg・・・・m/61 Ib・・・・in)
Bolt – 13 N・・・・m (1.3 kg・・・・m/113 Ib・・・・in)
Adjustment
1. Loosen the neutral start switch bolt and set the shift
selector to the “N” range.
2. Align the groove and neutral basic line (1).
3. Hold in position and tighten the bolt (2).
Torque: 13 N・・・・m (1.3 kg・・・・m/113 Ib・・・・in)

BRAKE SIGNAL INSPECTION
Check that the brake light comes on when the brake pedal
is depressed.

VEHICLE SPEED SENSOR 1 INSPECTION
1. Connect the Vehicle speed sensor connector terminal
(1) to the battery ( +) terminal and terminal (2) to the
battery (-) terminal.
2. Connect a resistance of 1.3k ohm to 5k ohm (1.4W or
more) between terminals (1) and (3).
NOTE:
Be extremely careful not to connect the battery (+)
terminal to the terminal (3).
This may damage the vehicle speed sensor.
3. Rotate the shaft of the vehicle speed sensor slowly and
measure the voltage at both ends with a digital tester.
The voltage, with one rotation of shaft, fluctuates four
times in the following range: 10 to 14V ⇔ 2V or less.
Replace the sensor when the result of inspection is
found abnormal.

VEHICLE SPEED SENSOR 2 INSPECTION
1. Disconnect the vehicle speed sensor 2 connector.
2. Use an ohmmeter to measure the resistance between
terminals 5 (SP2+) and 6 (SP2-).

ATF TEMPERATURE SENSOR
INSPECTION
1. Disconnect the front side ATF cooler pipe from the
elbow and remove the elbow.
2. Remove the ATF temperature sensor from the
transmission case.
3. Place the ATF temperature sensor in a container of
ATF.
