  3. Find the gap between the ABS wheel speed sensor pole piece and the surface of the tone wheel teeth by putting the measured values in the formula below and calculating.

    ABS wheel speed sensor clearance = B - A 

    ABS wheel speed sensor standard clearance: 

    0.3 - 0.8 mm (0.012 - 0.031 in) 

    NOTE: If the clearance is outside specification, readjust using spacer (Part No. 26755AA000).
