ABOUT OXYGEN SENSOR

HELLO FRIENDS I HAVE A PROBLEM IN MY VEHICLE IF I HAVE OXYGEN SENSOR UPPER DEFECTIVE, NOW I TAKE IT AT A NORMAL REPAIRER TO TAKE A BRAND AND A NORMAL REPAIRER.

sometimes there is a lack of contact with the cables and sometimes rust in the sensor sockets, there may be dust in my opinion, I think, check them first, then clean them, then delete them by deleting the error codes, if there is an error code, there is nothing to do if it does not correct the master who detected the malfunction, or even tell the particle if it does not. sometimes false determinations can be made,

must be a master to adapt. In addition, the sensor does not consist of two parts, either it is defective or not. this is the first time I have heard that six or more are faulty ...

Oxygen sensor is a very troubled instrument, I talked to the service, they produced bosch in them, they only hit the peugeot brand, it is twice as expensive, I know that when you buy it from the outside, they change it with 75tl workmanship price. after 4 thousand cycles in gasoline
