Brake Sensors, Rear

NOTE: If vehicle speed sensor indicator is damaged, refer to appropriate axle section in Group 05.

Removal

  1. Pull the wiring harness connector from the vehicle speed sensor (VSS) (9E731).

  1. Remove the vehicle speed sensor hold-down bolt and remove the vehicle speed sensor from the axle housing.

Installation

  1. Clean the axle mounting surface. Use care to prevent dirt from entering the axle housing.

  1. Inspect and clean the magnetized vehicle speed sensor pole piece to make sure it is free from loose metal particles which could cause erratic system operation. Replace the vehicle speed sensor O-ring.

  1. Lightly lubricate the vehicle speed sensor O-ring with motor oil, align the vehicle speed sensor bolt hole and install. Do not apply force to the plastic vehicle speed sensor connector. The vehicle speed sensor flange should slide to the mounting surface. This will make sure the air gap setting is between 0.127-1.14mm (0.005-0.045 inches).

  1. Install the vehicle speed sensor hold-down bolt and tighten to 34-40 Nm (25-30 lb-ft).
