REAR ABS WHEEL-SPEED SENSOR INSPECTION [2WD] 

INSTALLATION VISUAL INSPECTION 

1. Inspect the following items: 



If there is any malfunction, replace the applicable part.  

1. Excessive play of the ABS wheel-speed sensor  

2. Deformation of the ABS wheel-speed sensor  

CLEARANCE INSPECTION 

1. Remove the rear ABS wheel-speed sensor.  

2. Measure the distance between the rear ABS wheel-speed sensor installation surface and the ABS sensor 

rotor. This is dimension A.  

3. Calculate the clearance between the front ABS wheel-speed sensor and the ABS sensor rotor using the 

following formula: 

Clearance (mm {in}) = A-15.0 {0.60 in} 

4. Verify that the clearance between the ABS sensor rotor and the rear ABS wheel-speed sensor is as 

indicated below. 



If there is any malfunction, replace it.  

Clearance  



0.3-1.1 mm {0.012-0.043 in}
