Good evening and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.

*****I work part-time here on JustAnswer to help you and other repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating.. I will need for you to be my hands and eyes since I'm not there, and to be honest with today's electronics a scantool may very well be needed to retrieve the codes or to monitor data to see what's going on*****

I will need the last 8 digits of your VIN to make sure I get the correct wiring diagram..

Talk soon,

Thanks for the VIN!!

I ran your VIN thru Chrysler and just to make sure you know, you have two open recalls for the airbags so don't forget to bring it in so we can replace them for you free of charge!!

Ok I attached the O2 sensor wiring diagram to help and it looks like you have four O2 sensors.. Can you tell me if it's 1/1, 1/2, 2/1, 2/2 or passenger upper/lower, driver upper/lower?
