Unscrew oxygen sensor from exhaust pipe or catalytic converter housing.
Installation
Caution: When replacing an oxygen sensor, only use a sensor of the same design.
Coat only the threaded part of the sensor with BOSCH special grease. New sensors have such lubrication. Grease must not get into the groove and holes of the sensor housing. If possible, do not touch or contaminate the case of new sensors.
Attention: If the sensor is screwed in without a special high-temperature lubricant, it becomes impossible to turn it out over time.
Screw in the sensor and tighten it to 30 Nm.
Connect the plug connection of the sensor.
