Customer Question
My check engine light...

My check engine light came on and I had it diagnosed at auto zone, it read p0420 catalystic efficiency below threshold (bank 1)

Mechanic's Assistant: Does the light stay on, or does it blink?

The light stays on

Mechanic's Assistant: What is the make/model/year of your car?

2013 ford fusion se

Mechanic's Assistant: Are you fixing your Fusion yourself? What have you tried so far?

No, I wouldn;t know where to begin. The only thing I have done is take it to auto zone

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

That seems to be my only issue

This almost always means the catalytic converter has failed which is about a $500 job at a shop depending on where you go. If vehicle still runs fine then you can drive it without worrying about any problems but converter will need to be replaced for light to shut off. I'd either have this done at a exhaust shop or dealership, let me know if you have questions. Thanks.

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
