Sensor Gap

Measure clearance between tone wheel and ABS wheel speed sensor at whole periphery.

NOTE: If clearance is narrow, adjust by using spacer (Part No. 26755AA000).If clearance is wide, check the outputted voltage then replace the ABS wheel speed sensor or tone wheel if the outputted voltage is outside specification.

ABS wheel speed sensor clearance:

0.7-1.2 mm (0.028-0.047 in)
