PLEASE Help I JUST BOUGHT A 2005 ACURA TL 67,000 MILES A MONTH AGO THE CAR RUNS PERFECT FULL POWER AND NOW THE CHECK ENGINE IS ON SO I TOOK IT TO A MECHANIC AND AFTER HE SCANNED THE CODE P0420 SHOWED UP AND HE SAID IT COULD BE THE CATALYTIC CONVERTER WICH HE CAN FIX IT FOR $1000, PLEASE I WANT TO KNOW IF THIS ISSUE IN UNDER WARRANTY BY ACURA OR NOT? OR IS IT REALLY THE CATALYTIC CONVERTER ISSUE SINCE THE CAR RUNS FINE?
THANK YOU SO MUCH FOR YOUR ANSWER

Catalyst System Efficiency Below Threshold (Bank 1) is what the error code is. It could be caused by a bad O2 sensor which is nowhere near 1000 dollars to fix. OR it could be a bad catalyst, you can buy a High Flow one from here for around 200-300 buck and get them replaced or you can buy an OEM one for a little more and have that put on as well. In any case it shouldn't be 1000 dollars.

Also please do us a favor and turn the caps lock off, it seems like you are yelling at us!

1K for cats?
Is that for the OEM pcats parts included?

Way to much for a cat....if its the 3rd one especially...

Take it to someone else. This guy doesn't know what he's doing or he's trying to rip you off. If it is the cat, take a look at the emissions warranty to see if you're still covered.

Pretty sure that the 3rd cat will never throw a code because there are no sensors on it.

My money is on a bad O2 sensor....

Thank you all for your answers, today a friend of mine will work on my car he said he will take the cat and clean it with a deg raiser liquid and leave it overnight hopefully that will work.

^^^ This should be interesting...

cat cannot be cleaned, if that's the actual problem they will have to be replaced

clean it = hollowing it out.

I get that code from time to time, then it goes away. I have my money on a bad O2 sensor as well.

I want to see how bad the fire is once they light off those cats that have been soaking in degreaser! insurance paid up?

Its a bad o2 sensor.

nfnsquared

Yep, like I said, should be interesting....

You are still under the 8y/80,000 emission warranty. Go to the dealership to get it checked or replaced asap, don't wait until the warranty expires..

I Called the acura dealer but they said it's not covered even it's 2005 with 67,000 miles ...

simocali

is there any proof that i can show the dealer that the cat or the check engine light should be covered for the model 2005 acura tl 68,000 miles??

pohljm

cats should be covered as an emission component. O2 sensor not so sure about. look in your owners manual or warranty handbook
