Note:
- New oxygen excess sensors are supplied lubricated with a special assembly paste. This paste should not get into the slots for installing the oxygen excess sensor.
- If the sensor is reused, it is necessary to apply heat-resistant paste to the threaded part of the excess oxygen sensor before installation.
- After connecting the wiring harness connectors to the oxygen sensors, the wiring harnesses must be reconnected to their original positions.
