Installing a Sensor
- After vehicle has cooled sufficiently to prevent personal injury, unplug the connector and remove the sensor using a suitable tool.
- Carefully check the vehicle harness and connector for damage or corrosion.
- Check that the thread in the exhaust system is clean and in good condition before attempting to install the new sensor.
- Ensure you have selected the correct part number.
- Handle sensors with care to prevent damage - dropping a sensor could inflict damage to the ceramic, which would not be apparent during installation.
- During production an anti-corrosion compound is applied to the threaded portion of the sensor body. This is a sensor friendly grease compound and no other anti-seize compounds should be used as they may contain ingredients that could poison the sensor elements. Do not use any other cleaning or anti-rust solvents near the sensor body as this could similarly affect the element.
- Remove the protection cap just prior to fitting. Screw the sensor into place by hand then tighten to the specified torque setting ensuring that the wiring harness is not twisted as the sensor is screwed in.
- Secure the harness using the correct fixings, ensuring that the routing does not produce any kinks in the wires, touch any part of the exhaust system or other hot components and does not foul any rotating parts.
- Reconnect the harness connector.
- Torque Setting
M18 Sensors: 35Nm to 45Nm
M12 Sensors: 18Nm to 23Nm
Do not use an impact wrench or air tools
