Withdrawal
1. Disconnect the oxygen sensor connector. The plug connector is fixed at the front wall of the cabin. The 6-cylinder engine has 2 oxygen sensors. Accordingly, there are 4 plug connectors: 2 for sensor heating and 2 for signals. The connectors for heating the oxygen sensors are black and are located on the left and right of the front panel connector. The connectors for the encoder signals are located slightly below the connector plate, next to the black connectors.
2. Dissolve all tightening clamps, while marking the position of the clamps with a felt-tip pen.
3. Remove the oxygen sensor from the exhaust pipe.
Installation
1. Lubricate the oxygen sensor thread with G5 mounting paste.
Warning: Grease must not reach the edges on the oxygen sensor housing.
2. Insert oxygen sensor and tighten to 50 Nm.
3. Connect the plug connectors for the heating and signal circuits.
4. Secure electrical wires with clamps. Pay attention to the fact that the tie-down collars are installed in the same place where they were before removal. This is necessary in order to avoid touching the wires with the exhaust system.
