Hello Family:

Please how do I interpret and solve P2191 error code in my 2013 Sonata. The mechanics in my country are incompetent and have messed up my 2014 Kia Rio as such I don’t want to take any chances with my sonata. I want to be really educated on the error code so that if I take the vehicle to the mechanic, I will tell them what to check or change for me if necessary. Your advice/suggestions will be highly appreciated, thank you.

 

You might consider using a different shop.

You should be aware there can be several causes for this type problem. Your best bet is a shop that knows what they are doing
I would caution you regarding telling a (mechanic-used loosely) what to do/change for this reason.
If you pick the incorrect procedure and the mechanic does it and it does not solve the problem, you are expected to pay for the work because he/she did as you instructed..
If you did a little checking you will notice there is quite a list and either you can pick the ones you want or just provide the list to the "repair person"
Either way , it's a gamble.
