Catalyst and lambda sensor

[tesen pesen]

Hi, i have changed my catalyst it was bad and 3 lambda sensors but last was just one error code on the computer and i changed that one. Now im wondering like my gut throws me to an electrik error reading this sensor (Sorry my english in mechaniks is "rusty" im swedish) anyways what can be the issue with just the one sensor that is new that has the error code? Educate me im not a mechanic but im in learning process

So i have the error reader and deleted error codes but just the one top right lambda sensor comes back even if its the sensor is new.

Don't take my word for it, but it seems like the sensor could be:

• faulty
• wired differently, than your car needs to be (this problem is rare, but cannot throw it out)

What code do you have, because a part is new doesn't mean it is good

what engine do you have ??
