    Illustration 2g03357582

  4. Remove bracket (8). Remove catalytic converter pressure sensor (5) and the O-ring seals.

  5. Remove DPF pressure sensor (6) and the O-ring seal.

  6. Remove adapters (11), plugs (9), and the O-ring seals.

  7. Remove manifold (10) from plate (7).

Installation Procedure

  1. Install pressure sensor assembly (2) in the reverse order of removal.

      Note: Do not pre-tighten the sensor using the plastic portion of the sensor. Pre-tighten the sensor using the metal hex portion of the sensor. Damage can occur to the sensor if pre-tightened using the plastic portion of the sensor.

    1. Tighten DPF pressure sensor (6) to a torque of 10 ± 2 N·m (89 ± 18 lb in).
