Application
Description
- When measured by multi - meter (AC) :
output voltage > 70 mV
- When measured in oscilloscope :
output voltage ≥ 120 mV/P-P
Replace the sensor.
l
Check wire for ground and open.
l
Check connection of the wheel speed sensor con-
l
nector and ECU side connector.
(Standard air gap : 0.15 - 1.20 mm)
Check output voltage of the sensor by rotating the
l
wheel 1/2 - 1 revolution per second and shaking sen-
sor wire.
- When measured by multi - meter (AC) :
output voltage > 70 mV
- When measured in oscilloscope :
output voltage ≥ 120 mV/P-P
Replace the sensor.
l
Check wire for ground and open.
l
Check connection of the wheel speed sensor con-
l
nector and ECU side connector.
Measure air gap between wheel teeth and wheel
l
speed sensor and check installation of wheel tooth.
(Standard air gap : 0.15 - 1.20 mm)
Check output voltage of the sensor by rotating the
l
wheel 1/2 - 1 revolution per second and shaking sen-
sor wire.
- When measured by multi - meter (AC) :
output voltage > 70 mV
- When measured in oscilloscope :
output voltage ≥ 120 mV/P-P
Replace the sensor.
l
Check number of teeth on the wheel rotor and its
l
condition.
- Number of teeth : 52
Check valve relay voltage.
l
Check connection of connector and terminals in the
l
ECU and hydraulic modulator.
Check ground.
l
Check terminals for open or short.
l
(When connector is removed)
Replace the hydraulic modulator.
