To install:


CAUTION
 Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  1. Install the vehicle speed sensor and the retaining bolt. Install a new O-ring seal on sensor if necessary. Tighten the bolt to 10 Nm (89 inch lbs.).
  2.  
  3. Install the electrical connector at the sensor. Install the bolts securing the front transaxle brace to the transaxle and right cylinder head.
