Engine Speed Sensor: Adjustments
ADJUSTING CLEARANCE ON SPEED AND REFERENCE MARK SENSORSNote: A clearance of 0.8 mm is specified between the speed sensor and ring gear. If this clearance is correct, the reference mark sensor will be positioned correctly automatically.
The reference mark sensor clearance will only have to be adjusted in the case of damage or replacement of the locked reference mark screw.
Adjusting with Engine Removed
1. Bolt speed sensor on bracket.
2. Unscrew bolts on bracket. Adjust clearance between gear ring and speed sensor with a 0.8 mm feeler gauge blade.
Adjusting with Engine Installed
1. Remove speed sensor.
2. If available, a defective sensor could be used as an adjusting tool. Then paste a 0.6 mm thick washer (for clearance) on sensor with a suitable quick-drying glue. The car's sensor could also be used when work is performed carefully. The adhesive surface should then be kept as small as possible or an easily removable glue should be used.
3. Loosen bolts on bracket and tighten again finger tight so that bracket can still be pivoted at bottom bolt.
4. Install longer sensor in speed sensor opening and tighten.
5. Move bracket with long sensor against stop (gear ring) and then tighten bracket bolts.
6. Remove longer sensor. If car's sensor was used, pry off glued washer carefully and remove remainders of glue.
7. Install speed sensor. Tightening torque: 8 Nm (6 ft lb).
