Sensor Gap

Check the gap between the tone wheel and the ABS wheel speed sensor around the entire circumference.

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

ABS wheel speed sensor gap standard value:

0.7 - 1.2 mm (0.028 - 0.047 in)
