  6.  
  7. Tighten sensor attaching bolt to 34-50 inch lbs. (4-6 Nm).
  8.  
  9. If original sensor has been installed, check sensor air gap. Air gap should be 0.40 to 0.0157 to 0.051 inches (1.3 mm). If gap is incorrect, sensor is either loose, or damaged.
  10.  
  11. Route sensor wire and install into mounting retainers.

  7. Install sensor bolt finger tight only at this time.
  8.  
  9. If original rear sensor was installed, adjust sensor air gap to 0.011-0.059 in. (0.28-1.5 mm). Use feeler gauge to measure air gap . Tighten sensor bolt to 106-124 inch lbs. (12-14 Nm).
  10.  
  11. If new sensor was installed, push cardboard spacer on sensor face against tone ring . Then tighten sensor bolt to 106-124 inch lbs. (12-14 Nm). Correct air gap will be established as tone ring rotates and peels spacer off sensor face.
