Removing oxygen sensors in front of catalytic converter

Illustration shows oxygen sensors on the right side

-2- Oxygen sensor behind catalytic converter on the right side

Oxygen sensor plug

-

-1- Plug for sensor in front of catalytic converter with plastic clip (rectangular)

-

-2- Plug for sensor behind catalytic converter (oval)

NOTE:  Observe precautionary measures when using oxygen sensor.

Oxygen sensor, left side:

1. Remove air cleaner housing.
2. Separate the rectangular plug connection for the oxygen sensor in front of the catalytic converter in the left engine compartment -1-. To do this,

first open the plastic securing clip.

3. Unclip the oxygen sensor wire in front of the catalytic converter from the wire retainer and the sheetmetal clips.

NOTE:  Always expose oxygen sensor wire so that the wire can turn when unscrewing the sensor.
