Installation 5. CAUTION: Make sure that the mating faces are clean
and free of foreign material.

Torque: 48 Nm
1. CAUTIONS:


If accidentally dropped or knocked install a new sensor.

Make sure the catalyst monitor sensor wiring harness is not twisted
more than 180 degrees and is not in contact with either the exhaust or
driveshaft.

Make sure the anti-seize compound does not contact the catalyst
monitor sensor tip.


NOTE: If the original sensor is to be installed, apply lubricant
meeting specification ESE-M12A4-A to the thread of the sensor.
To install, reverse the removal procedure.


2. NOTE: For NAS vehicles only.

If required, carry out a long drive cycle.

Refer to: Powertrain Control Module (PCM) Long Drive Cycle Self-Test (303-14D Electronic Engine Controls - V8 S/C 5.0L Petrol, General
Procedures).
