REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).II - REMOVING THE UPSTREAM OXYGEN SENSOR
aDisconnect the upstream oxygen sensor connector
(1) .
aRemove the upstream oxygen sensor (2) using a
24mm open-ended spanner.
III - REMOVING THE DOWNSTREAM OXYGEN
SENSOR
aDisconnect the downstream oxygen sensor connec-
tor.
aRemove the downstream oxygen sensor (3) using a
24mm open-ended spanner. Equipment required
open-ended spanner
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).

WARNING
Do not use any product designed to improve the

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.
