Heated oxygensensorsarefittedtothedownpipeassembly (1 Fig.l)which isconnectedtothemanifold (2 Fig.1). There
are two sensors for the ROW and Japan (3 Fig.1) and two additional sensors (4 Fig.1) for NAS markets.
The sensors are located upstream and downstream of catalytic converters.
Apart from two heated oxygen sensors, the exhaust system for vehicles destined for the Japanese market are also
fitted with two exhaust gas temperature sensors
(5 Fig.1).
The exhaust system is held in a predetermined position by a fixing arrangement to the manifold by exhaust centre
mountings (6 Fig.l), by rear axis mountings (7 Fig.l), and tail pipe mountings (8 Fig.1).
Clamps (9 Fig.1) used on each slip joint are welded to the pipes and tightened to a higher torque setting than non- welded clamps.
The exhaust system must be free of leaks, binding, grounding and excessive vibrations. These conditions are usually
caused by loose, broken, or misaligned clamps, shields, brackets, or pipes. Should any of these conditions
exist,check the exhaust system components and alignment. Adjust and renew if necessary. Do not attempt to service brackets,
clamps and insulators.

J30-234
Fig. 1 Plan View of Exhaust system
'he low
-loss catalytic converter exhaust system for the VI2 engine comprises catalyst/downpipe assembly with addi- tional secondary catalytic converters (1 Fig.11, a underfloor catalytic converter assembly (2 Fig.1) complete with heat
shield (3 Fig.l), an intermediate muffler section (4 Fig.1) and a rear muffler section (5 Fig. 1).
On non-catalytic converter systems, the downpipe/catalyst assembly is fitted with conventional twin branch down- pipes (6 Fig.11, hence there are no oxygen sensors or exhaust gas temperature sensors.
Conventional mufflers are fitted in place of the underfloor converters.

Two heated oxygen sensors are fitted to the downpipe assembly (1 Fig.1) which is connected to the manifold and two
on the underfloor catalytic converter assembly in front of the catalysts. There are two sensorsfor the ROW and Japan
markets (2 Fig.1) and two additional sensors (3 Fig.1) for the NAS markets.
The sensors are located on A
-bank and B-bank, upstream and downstream of catalytic converters.
Apart from two heated oxygen sensors, the exhaust system for vehicles destined for the Japanese market are also
fitted with two gas temperature sensors
(4 Fig.1).
The exhaust system is held in a predetermined position by a fixing arrangement to the manifold by exhaust centre
mountings (5 Fig.l), by rear axis mountings (6 Fig.1). and tail pipe mountings (7 Fig.1).
Clamps (8 Fig.1) used on each slip joint are welded to the pipes and tightened to a higher torque setting than non- welded clamps. ~ ~~~
