11.12.3. Lambda sensor

Removal

PERFORMANCE ORDER
1. A lambda sensor it is screwed in in a reception exhaust pipe and access to it it is possible from under the car.
2. Lift a forward part of the car and fix on supports or establish the car over a viewing hole.
3. Removal the Lambda sensor is desirable for making after cooling of the engine and an exhaust system.
4. Working under the car, remove the metal filter and disconnect the electric socket of Lyambda-datchi, fixed on the body bottom. For a detachment of the electric socket turn it on a turn quarter counter-clockwise and take from a nest.
Prevention

On later models the electric socket the Lambda sensor is located in car salon under a rug for feet of the driver. Disconnect the electric socket the Lambda sensor and take it through a sealing ring in the car bottom.


5. Being careful, unscrew the Lambda sensor from a reception exhaust pipe.

Installation

PERFORMANCE ORDER
1. Put on a carving the Lambda sensor a thin layer of an antiprigarny material. Thus be careful, that the antiprigarny material did not get on a working tip of the sensor.
2. Screw in the Lambda sensor in a reception exhaust pipe, tighten it the demanded moment and connect the electric socket of the sensor.
