General Procedures


WARNING: Where possible, all road tests should be on well surfaced and dry roads. Always comply with speed limits and
local traffic regulations.
NOTES:


This procedure is an overcheck only. If fault codes are found, interrogation of the relevant system must be carried out and
claimed against.


The vehicle must exceed 50mph (80 km/h) during the road test.

1. Connect the diagnostic equipment to the vehicle.

2. Follow on screen prompts and check for engine management fault codes.

3. Clear the fault codes following the on screen procedure.

4. Disconnect the diagnostic equipment from the vehicle.


5. NOTE: Make sure cruise control is not engaged. Make sure
the engine temperature is above 60 ºC (140 ºF).
Carry out a road test and perform the following operations.
1. Accelerate to 55 mph (88 km/h) in 5th gear and cruise for 2
minutes with the engine speed at or above 1800rpm.
2. Lift off the throttle and allow the vehicle to decelerate until the
engine speed is less than 1000 rpm.
3. Stop the vehicle.
4. Release brake, allow the vehicle to move with no throttle for 1
minute.
5. Road test is now complete.

6. Connect the diagnostic equipment to the vehicle.


7. NOTE: If fault codes are found, interrogation of the relevant
system must be carried out and claimed against.
Follow on screen prompts and check for engine management fault codes.

8. Disconnect the diagnostic equipment from the vehicle.

1. Connect the diagnostic equipment to the vehicle.

2. Follow on screen prompts and check for engine management fault codes.

3. Clear the fault codes following the on screen procedure.

4. Start the engine.
Allow the engine to idle for 30 seconds.
Raise the engine speed to 1500 rpm and hold for 3 minutes until
a temperature of 70ºC (158 ºF) is achieved.
Allow the engine to idle for 30 seconds.
Switch off the engine.


5. NOTE: If fault codes are found, interrogation of the relevant
system must be carried out and claimed against.
Follow on screen prompts and check for engine management fault codes.

6. Disconnect the diagnostic equipment from the vehicle.

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).
