Oxygen Sensor: Service and Repair

Fig. 150 LAMBDA SOND:





1. Apply anti-seize (Volvo part number 1161035-9 or equivalent) to sensor threads.

2. Ensure that no paste enters the slots on the tip. (This will render the oxygen sensor ineffective.)

3. Torque the oxygen sensor to 40 ft.lbs (55 Nm).
