Removal
1. The lambda sensor is screwed into the exhaust pipe and can be accessed from underneath the vehicle.
2. Raise the front of the vehicle and secure it on stands or place the vehicle over an inspection pit.
3. It is advisable to remove the Lambda sensor after the engine and exhaust system have cooled down.
4. Working underneath the vehicle, remove the metal protective shield and disconnect the Lambda Sensor electrical connector secured to the underbody. To disconnect the electrical connector, turn it a quarter turn counterclockwise and pull it out of the socket.
Caution! On later models, the Lambda Sensor electrical connector is located in the passenger compartment under the driver's foot mat. Disconnect the Lambda Sensor electrical connector and pull it out through the sealing ring in the underbody of the vehicle.
5. Carefully unscrew the Lambda sensor from the exhaust pipe.
Installation
1. Apply a thin layer of non-stick material to the threads of the Lambda sensor. Be careful not to let the non-stick material get on the working tip of the sensor.
2. Screw the Lambda sensor into the exhaust pipe, tighten it to the required torque and connect the sensor electrical connector.
