I have a 2014 VW Jetta SE and want to know the socket size for the down stream, number 2, oxygen sensor??

What is your question?

It is the 2nd oxygen sensor after the catalytic converter,,I just need to buy the right socket size to remove and replace it..Thank you

What makes this problem better or worse?

The mechanic reset the codes but it came back on,,of course

How long has your 2014 Volkswagen Jetta had this problem?
