00 Integra GS w P0420
The CEL is pop up so I went to Autozone to scan it ..the P0420 is the code that they gave me . The guy told me its 02 sensor but I don't know is it the upstream ( primary ) or the downstream ( underneath the car ) or maybe because of my CAT ? Can someone help please ?

Re: 00 Integra GS w P0420
I had this code in a 00 civic ex one time.
Do you have the cat on there still? |
Re: 00 Integra GS w P0420
Everything is still intact so how did u solve urs ?

Re: 00 Integra GS w P0420
Check for exhaust leaks before or in the cat. Otherwise generally its a bad cat.

Re: 00 Integra GS w P0420
Hmm ok so it's not O2 sensors at all ?

Check for exhaust leaks, as directed before. If none, then the cat has deteriorated below the threshold that the engine's computer is programmed to consider acceptable. One thing that dramatically reduces cat life is to allow the car to run out of gas, or to drive around with a very-low gas tank level. Honda warns about this in later Owner's Manuals. |

It's an inefficiency code, this might help...

Re: 00 Integra GS w P0420
Standard code for bad catalytic converter. Can be caused by o2 sensor, but unlikely. If the Pri or Sec O2 sensor is bad, it will normally set off the code for a bad sensor.
Just an FYI, if you burn a lot of oil, plan on replacing it again within a couple years. I got sick of dealing with P0420 and got an O2 extender, but that won't work if you're trying to pass smog. |
Re: 00 Integra GS w P0420
Lets just if the CAT was bad ..what do I need to get replace with ? OEM Honda one ? Man I bet it would be pricey :( . Any other brand that you can guys recommend ? I kinda still confused when the code says bank 1 but its not necessary mean O2 sensors hmm ... How do I check the CAT to know if its bad or not ? We don't have smog check here so can I just run w/o CAT but the CEL is still on ?

Re: 00 Integra GS w P0420
Just had the same code replaced the cat and no more light

Re: 00 Integra GS w P0420
May I ask what type of cat did u replaced if u don't mind I'm asking or maybe a part # so I can order one ?
|
Re: 00 Integra GS w P0420
What do you guys normally replace with ? Maybe a part # would help ...
|
Re: 00 Integra GS w P0420
these fit 95, probably some others. search your model to double check.

Re: 00 Integra GS w P0420
looks too brand x imho.
personally i'd spend a bit more for the eastern catalytic model since it has the little <3 next to it = most purchased. they could be made by the same chinese factory tho, who knows. http://www.rockauto.com/catalog/more...972&cc=1000382 |
