REMOVING THE UPSTREAM OXYGEN
SENSOR
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aRemove:
-the front right-hand wheel (see Wheel: Removal -
Refitting) (35A, Wheels and tyres),-the front right-hand wheel arch liner (see Front
wheel arch liner: Removal - Refitting) (55A, Ex-
terior protection),
-the engine undertray.
II - REMOVAL OPERATION
aDisconnect the upstream oxygen sensor connector
(1) .
aUnclip the wiring from the upstream oxygen sensor
at (2) .
aRemove the upstream oxygen sensor . Special tooling required

WARNING
Do not use any product designed to improve the
electr ical contact in the injection computer and oxy-
gen sensor connectors or on the bodies of the oxy-
gen sensors.
Failure to respect this advice prevents the oxygen
sensor from operating correctly and results in fail-
ure to comply with the emission control standard.
WARNING
If the connections are corroded, repair the wiring
(see Wiring: Precautions for repair) (Technical
Note 6015A, 88A, Wiring).
Note:
This procedure is for removal - refitting of the
upstream oxygen sensor and the downstream oxy-
gen sensor.

REFITTING THE UPSTREAM OXYGEN
SENSOR
I - REFITTING PREPARATION OPERATION
aClean the threading of the upstream oxygen sensor
using a WIRE BRUSH.
aUse SURFACE CLEANER (see Vehicle: Parts
and consumables for the repair) (04B, Consuma-
bles - Products) to clean and degrease:
-the thread hole of the upstream oxygen sensor on
the exhaust manifold,
-the threading of the upstream oxygen sensor if it is
to be reused.
II - REFITTING OPERATION
aRefit the upstream oxygen sensor.
aAngle tighten the upstream oxygen sensor ( 90˚).
aAttach the upstream oxygen sensor wiring.
aConnect the upstream oxygen sensor connector.III - FINAL OPERATION
aRefit:
-the engine undertray.
-the front right-hand wheel arch liner (see Front
wheel arch liner: Removal - Refitting) (55A, Ex-
terior protection),
-the front right-hand wheel (see Wheel: Removal -
Refitting) (35A, Wheels and tyres).
REMOVAL OF THE DOWNSTREAM
OXYGEN SENSOR
I - REMOVAL PREPARATION OPERATION
aDisconnect the battery (see ) (80A, Battery).
aRemove:
-the windscreen wiper arms (see Windscreen wip-
er arm: Removal - Refitting) (85A, Wiping -
Washing),
-the scuttle panel grille (see Scuttle panel grille:
Removal - Refitting) (56A, Exterior equipment),
-the scoop under the scuttle panel grille (see Scoop
under the scuttle panel grille: Removal - Refit-
ting) (56A, Exterior equipment).

Note:
For angular tightening, make a mark (6) on the
catalytic pre-converter in the middle of the flat
surface of the upstream oxygen sensor. Move the
upstream oxygen sensor stop (7) to the mark (6)
.
