Sensor Gap

  1. Check tone wheel's teeth (44 pieces) for cracks or dents. If necessary, replace tone wheel with a new one.
  2. Clearances (sensor gaps) should be measured one by one to ensure tone wheel and speed sensor are installed correctly.
NOTE:
  • If clearance is narrow, adjust by using spacer (Part No. 26755AA000).
  • If clearance is wide, check the outputted voltage then replace ABS sensor or tone wheel if the outputted voltage is outside the specification.

ABS sensor clearance: 

  1. Front:  0.3 - 0.8 mm (0.012 - 0.031 in)
  2. Rear:  0.7 - 1.2 mm (0.028 - 0.047 in)
