SENSORGAP
Clearances (sensor gaps) should be measured one
by one to ensure the tone wheel and speed sensor
are installed correctly.
NOTE:
If clearance is narrow, adjust by using the spacer
(Part No. 26755AA000).
If clearance is wide, check the outputted voltage
then replace the ABS sensor or tone wheel if the
outputted voltage is outside the specification.
