Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

This code is for the downstream NOx sensor. This could be a wiring issue but is almost certainly the sensor itself. The sensor threads into the exhaust like an oxygen sensor and the module attached to it is mounted to the frame with two 10mm nuts.

You could replace the sensor yourself but I would recommend seeing your dealer. This should be covered under federal emissions warranty and isn't something you'll want to pay for if you don't have to.

What Customers are Saying:

I AM VERY GLAD THAT I TOOK A CHANCE ON YOUR PROBLEM SOLVING SKILLS. I WAS SUCCESSFUL IN REPLACING THE FUEL PUMP. MY TRUCK RUNS LIKE A CLOCK. IT RUNS LIKE THE DAY I BOUGHT IT. NO LUNGING FORWARD, THE TURBO REACTS THE SECOND I STOMP ON THE GAS, AND IT HAS A LOT MORE POWER AND EVEN SOUNDS BETTER TO ME. IT SAVED ABOUT $500.00 BY DOING THE WORK MYSELF. I GIVE YOU ALL THE CREDIT FOR YOUR DIAGNOSING THE PROBLEM, JUST FROM THE SYMPTONS I GAVE YOU OVER THE e MAIL. I WILL USE YOUR WEB SITE AGAIN AND REFER MY FRIENDS. THANKS SO MUCH FOR THE HELP.
