DESCRIPTION
Use the following repair procedure to minimize the need to replace the catalyst converter/exhaust pipe when removing oxygen sensors and/or air fuel
ratio sensors.
REPAIR PROCEDURE
Oxygen Sensor Removal Procedure
WARNING:
To avoid personal injury, allow exhaust system to cool down before removing oxygen sensor.
NOTE:
In some cases oxygen sensor and/or air fuel ratio sensor seizure will occur during this removal procedure. If seizure occurs, remove the converter or
exhaust pipe from the vehicle and re-attempt removal with the assembly placed in a vise. This will maximize your positioning and ability to apply
adequate torque to remove the sensor.
1. If reusing oxygen sensor, mask it with masking tape to prevent lubrication soaking.
