Hi, I’m Ron and I’ll be helping you today.
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

Resetting it won't do anything except clear the codes, BUT, then the monitors won't be complete for three drive cycles. The problems need to be fixed in order to pass emissions. They know if it's been tampered with. Here is the attachment for clearing it though if you want to try it anyway:)

Thanks, Ron

Given the codes that I provided.....what would estimate repairs would cost? I know it's tough without actually seeing it. Just a rough estimate so I don't get ripped off.
Expert:  rpmdiag replied 1 year ago.
Roughly 400 dollars.
Thanks again, and please don't forget to rate me and keep this link in case you need me again later on.
