2) Measure ABS sensor resistance.
ABS sensor Terminal No. Standard
Front - LH 1 and 2
1.0±0.2 kΩ Front - RH 1 and 2
Rear - LH 1 and 2
Rear - RH 1 and 2
CAUTION:
If resistance is outside the standard value, replace
ABS sensor with new one.
NOTE:
Check ABS sensor cable for discontinuity. If necessary,
replace with a new one.
G4M0448
2. TONE WHEEL
1) Check tone wheel’s teeth (44 pieces) for cracks or
dents. If necessary, replace tone wheel with a new one.
2) Clearances (sensor gaps) should be measured one by
one to ensure tone wheel and speed sensor are installed
correctly.
ABS sensor clearance:
Front
0.9—1.4 mm (0.035—0.055 in)
Rear
0.7—1.2 mm (0.028—0.047 in)
NOTE:

If clearance is narrow, adjust by using spacer (Part No.
26755AA000).

If clearance is wide, check the outputted voltage then
replace ABS sensor or tone wheel if the outputted voltage
is outside the specification.

14. Vehicle Speed Sensor 2
A: GENERAL PRECAUTIONS
1) Be careful not to drop or bump sensor as this may break
built-in magnet.
2) Drive key is designed to separate from vehicle speed
sensor 2. Be careful not to lose it or forget to install.
3) Vehicle speed sensor 2 is installed in part (which con-
tains bearings, etc., finished to a high degree of accuracy).
Do not allow foreign matter (filings, sand, etc.) to get into
it.
4) When checking output of vehicle speed sensor 2 as a
single unit, ensure test leads are connected to their correct
terminals. Failure to do this may damage internal IC.
5) Discard vehicle speed sensor 2 after removal; replace
with new one.
B: REMOVAL
CAUTION:

Be careful when removing vehicle speed sensor 2
immediately after driving vehicle for a while, as tem-
perature around it is high.

Before removing vehicle speed sensor 2, clean dirt,
etc. from surrounding areas. Take care not to allow
foreign matter to get into mounting hole.
B2M0211
1) Remove collector cover.
2) Disconnect vehicle speed sensor 2 connector.
3) Turn and remove vehicle speed sensor 2.
4) Remove key and packing.

C: INSTALLATION
CAUTION:

Ensure sensor mounting hole is clean and free of
foreign matter.

Apply grease to tip end of key to prevent key from
falling off sensor.

Align tip end of key with key groove on end of
speedometer shaft during installation.
1) Hand tighten vehicle speed sensor 2, then tighten it
using suitable tool.
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:
5.9±1.5 N⋅m (60±15 kg-cm, 52±13 in-lb)
