10.13.11. Lambda sensor

Removal

Removal of a metal protective cap Lambda sensor

 


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. Further work make only after complete cooling of the engine and an exhaust system.
4. Disconnect the electric socket located on wires the Lambda sensor. For a detachment of the 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 and take it through condensing ring in the bottom.


5. Remove a metal protective cap, then unscrew the Lambda sensor from a reception exhaust pipe (see drawing).

Installation

PERFORMANCE ORDER
1. Apply a thin film antiprigarny structure on a carving the Lambda sensor, thus watch, that the antiprigarny material did not get on a sensor tip.
2. Screw in the Lambda sensor in a reception exhaust pipe and tighten it the demanded moment then connect the electric socket of the sensor.
