3. Cut cable straps (4) from harness assembly (2). Disconnect harness assembly (5). Remove module (6) and nitrogen oxide sensor (1).

Installation Procedure

1. Install nitrogen oxide sensor (1) in the reverse order of removal.

   1. Lightly lubricate the threads of nitrogen oxide sensor (1) with Tooling (B).

      Note: If a new nitrogen oxide sensor is being installed do not apply Tooling (B) to the threads. New nitrogen oxide sensors should have the required lubricant already on the threads.

   2. Use Tooling (A) to install nitrogen oxide sensor (1) into the clean emissions module. Tighten nitrogen oxide sensor (1) to a torque of 50 N·m (37 lb ft).
