Seville STS V8-4.6L VIN 9 (1998)
Pull to Seat Connectors
The following is the proper procedure for the repair of Weather Pack(R) Connectors.
^
Separate the connector halves (1).
^
Open the secondary lock. A secondary lock aids in terminal retention and is usually molded to the connector (1).
^
Grasp the wire and push the terminal to the forward most position. Hold the wire in this position.
Pull to Seat Connectors
^
Insert the Weather Pack(R) terminal removal tool into the front (mating end) of the connector cavity until it rests on the cavity shoulder (1).
^
Gently pull on the wire to remove the terminal through the back of the connector (2).
IMPORTANT: Never use force to remove a terminal from a connector.
^
Inspect the terminal and connector for damage Repair as necessary. Refer to Repairing Connector Terminals.
^
Reform the lock tang (2) and reset terminal in connector body.
^
Close secondary locks and join connector halves.
^
Verify that circuit is complete and working satisfactorily.
^
Perform system heck.
Flat Wire Repairs
NOTE: The flat wire within the flex wiring harness is not serviceable. If an open or short exists within the flex wiring harness the complete harness
must be replaced.

HO2S Wiring Repairs
NOTE: Do not solder repairs under any circumstances as this could result in the air reference being obstructed.
If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to
repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is
obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of
the air reference and degrade oxygen sensor performance.
The following guidelines should be used when servicing the heated oxygen sensor:
^
Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor
performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a
path for foreign materials to enter the sensor and cause performance problems.
^
Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the
lead wire.
^
Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as
the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.
^
To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector.
