I have an 09 focus S manual tranny. I take great care of my care and have a goal to make it last 500,000 miles. I drive far for work mostly highway and I got 125,000 now.
recently my check engine light came on and after getting it checked the computer read PO420 Catalyst System Efficiency Threshold Bank 1. I was told it may be my Catalytic Converter and after a failed attempt of putting catalytic converter cleaner in my gas which advanced auto recommended, I ordered a new Walker direct fit catalytic converter from autopartswarehouse for $115 http://http://www.autopartswarehouse.com/sku/Hyundai/Elantra/Walker/Catalytic_Converter/2001/GLS/4_Cyl_2-dot-0L/WK93253.html?loc=Rear&intcmpid=Product+Listings+Best+Seller
I have a little self mechanic knowledge, So my questions are 1. Is a focus catalytic converter bolted or welded on, I can not weld so if thats the case I will take it to a shop. 2. If this replacement does not work I plan on replacing the oxygen sensors. Is this the right direction or should I be doing something else

So,
opening you hood and looking at you car was out of the question?


Bring it to a shop.

Link's not working, and I doubt you'd get a "direct fit" replacement mani-cat (manifold & cat combination) for that price.

Needs a better look with diagnostic tools to see if the sensors seem to be working - jumping straight to a CAT replacement can be pricey.

Cleaner eh? Another new nostrum to take the $ I see...

So what is the best option to take? Where do you get readings done. It is costing me 250 parts and labor to replace my cat which I cant really undo that. I am pretty much against taking it to a shop unless I really need to. I just cant imagine paying someone $100 a freaking hour who does not care how much money it costs me in the end to do something I am capable of doing myself.

You can do some good troubleshooting yourself at home with an IR Temp gun & a Scan tool to monitor O2 sensor performance. Please watch this video->

BTW never heard of needing to do any welding when replacing a cat on a Focus.... even a Focus that has 2 cats... all are bolt-on.

So tell me how you're able to do this yourself when you can't weld?
(the parts you bought are weld in parts)

If you can't even take some time to search out how to replace the catalytic converter or even what it looks like prior to purchasing parts, do you honestly think you're going to be able to do anything?



This is not a job you're able to do. So me/us telling you how to do it properly is a waste of breathe. Even me responding is a waste of my time.
There is a good reason shop time is what it is, and thank you for proving that (have to fix other peoples [:)][:)][:)][:)]ups).

I personally find something wrong with a 'direct fit' cat for an '09 at only $150, usually quite a bit higher than that. Sounds like a universal type one to me. Direct fit means it includes any pipe welded to the converter, universal one you cut the pipe to fit converter and may only need exhaust pipe clamps with no welding at all but you must be accurate when cutting the pipe.

go to autopartswarehouse.com and look up the part. I am not getting the entire assembly just the part with the honeycomb stuff inside.

If you actually read the original post I asked if it is a bolt on because if it is I can handle that. I can not weld because I do not have anything to weld with. Thanks for being a sterotypical forum [:)][:)][:)][:)][:)][:)][:)] who looks for any chance possible to jump on someone who has less knowledge than you with a car though.

Hey not everyone here are like that, so to say the "forum" in general is wrong. I work at a parts retailer I will look it up in a few and get back to you with what is needed for your vehicle... the link you posted is not working, where did you get the cat you have? Part number if possible thanks

From the $250 for CAT & labor, it sounds like you're replacing the secondary CAT which isn't monitored by the car's PCM & won't show a "code" when it fails.

Primary is part of the manifold, and which type depends on whether your car is a PZEV type or not. In PA either could have been sold - CA & northeast states compliant (PZEV) or the version for other states not using CA standards.

The manifold/CAT/Flex is a bolt on part, picture of both types have been posted already in the thread. IF it's a PZEV type, the correct manifold gasket is needed to function properly, or the next code will be for an air injection system fault.

Yea I didnt say the forum in general is like that, I said stereotypical forum donkey holes by my actual words were filtered by the site.

The part number was WK93251, I canceled the order since I do not know if it is correct. So I am at square 1. I have the code, what do I change out first?

You do not replace anything first.
First, you decide to troubleshoot it yourself or take it to a pro.

You can do some good troubleshooting yourself at home with an IR Temp gun & a Scan tool to monitor O2 sensor performance. Please watch this video->

IF the cat is bad, another concern is to ask-> what might have contributed or caused the cat to fail; this often requires the skill of an experienced tech to determine.
