4) When tester indicates 12 volts when its probe reaches
point“A”, a broken circuit occurs between point“A”and the
negative terminal. Slowly move tester probe toward the
negative terminal while contacting it on heat wire to locate
point where tester indication changes abruptly (0 volts).
This is the point where a broken circuit occurs.
When tester indicates 0 volts when its probe reaches point
“A”, a broken circuit occurs between point“A”and the posi-
tive terminal. Locate a point where tester indication
changes abruptly (12 volts) while slowly moving tester
probe toward the positive terminal.

Tightening torque required for sensor to reach bottom of
transmission is as follows:
Tightening torque:
0.39—0.88 N⋅m (4.0—9.0 kg-cm, 3.5—7.8 in-lb)
CAUTION:

When torque must be applied that exceeds 0.88 N⋅m
(9.0 kg-cm, 7.8 in-lb), the key and key groove on end of
speedometer may not be aligned properly. Remove the
key, align it correctly and reassemble.

Sensor threads are secured by Locktite. The reas-
sembly must be completed within 5 minutes before
Locktite dries.
2) Tighten vehicle speed sensor 2 further to specified
torque.
Tightening torque:
