Withdrawal
Note: The oxygen sensor uses a permanently fixed electrode and connector. This electrode must not be removed from the oxygen sensor. Damage or removal of the electrode or connector may impair the performance of the oxygen sensor. Be careful when handling the oxygen sensor. Don't drop it.
1. Disable «-» battery wire.
2. Remove the oxygen sensor connector (O2S).
Note: At engine temperatures below 48°C, it may be difficult to remove the oxygen sensor. Excessive force may result in stripped threads in the exhaust manifold.
3. Carefully remove the oxygen sensor (O2S).
Installation
Attention: a special non-stick compound is applied to the threads of the oxygen sensor. This composition consists of liquid graphite and glass granules. The graphite will burn off later and the glass beads will remain, making the sensor easier to remove. A new or refurbished sensor will be treated with this compound on the threads. If the sensor is removed from the engine or needs to be reinstalled, a coat of non-stick compound must be applied prior to reinstallation.
1. Coat the oxygen sensor threads with non-stick compound if necessary.
2. Install oxygen sensor (O2S) and tighten to 42 Nm.
3. Connect the oxygen sensor.
4. Connect «-» battery wire.
