REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
II - OPERATION FOR REMOVAL OF PART
CONCERNED
1 - Removing the upstream oxygen sensor
aRemove the air filter unit (see 12A, Fuel mixture,
Air filter unit: Removal - Refitting, page 12A-13) .aDisconnect the upstream oxygen sensor connector
(1) .
aUnclip the upstream oxygen sensor connector from
the rocker cover.
aUnclip the upstream oxygen sensor wiring (2) .
aRemove:
-the bolts (3) from the exhaust manifold heat shield,
-the turbocharger heat shield,
-the upstream oxygen sensor (4) from the catalytic
converter using the tool (Mot. 1495-01). 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 causes the oxygen
sensor to malfunction and results in failure to com-
ply with the emission control standard.
WARNING
If the connections are corroded, repair the wiring
(see Wiring: Precautions for repair) (Technical
Note 6015A, 88A, Wiring).
