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).
