Hi, guys I'm not so familiar with cars and stuff but I got some problems with some misfires in my engine. I decided to download some software/buy cable and check it out by my self.
So in the INPA Software I saw the following, that the Lambda sensor I'm not sure which one is which, but one of them is showing above allowed values.
So I assumed that it is the Post-Cat Bank 2 sensor, when I decided to look under to check it out, I only found one sensor.
This is my catalytic:
I'm not sure if I got it right or not, because if you translate it, it says [Post Cat sensor Bank 2] , but it depends on how you look at it. Which one is which? If you look at it from above your motor cap down, the post catalytic becomes the bottom one, but if you look at it from the bottom of your car then it suddenly becomes the upper sensor. I'm so confused. Is there any way to find out which one I need to change?
I have bought this one from some car dealer, it is used one. But I assume I got the wrong one, not sure.
