Update. Yesterday, after 4800miles got check engine. Its weird because codes for both sides.. I dont think both cats can throw the codes at same tile... could be bad fuel, because prices just dropped down and probably quality too. Did reset, add seafom...will see how lond will last. But still almost 5k its already good.
Why you are not looking to replace cat. You already spend quite a bit on replacing sensor. I think problem lies with Cat. I got code on 2014 QX60 for Bank 1 and looking to replace the cat.
@@malikammar8404 one side aftermarket with labobor $1000. Had codes for both sides randomly its already $2000. +many other issues...going to replace rear air struts +hydrolic bleeding...+possibly have to replace radiator...dont want to sepent money
Unfortunately After 2000...miles got po430 again. Did reset. Runs good. Will see when will get this code back again. Definitely dodnt want to replace cats.
Update 7.21.24 Made 2700 miles after last check engine light. Was using "seafom" injectors cleaner $6/bottle for half tank. Ate least 3..4 bottles needed
Hi there. I am having issues idle high, not running correctly. Thank you. Car repair keeps telling me nothing is wrong with my vehicle. I am in ROC. Any suggestions!?
The code came back after 2k miles. Also I was using Cataclen maybe 10 bottles before replaced sensors. Now im isung stuff to clean fuil system and liquimolly for injectors cleaning... so far 400 miles. What sensor you replaced ? Just one or both upstream and downstream?
@@adamparris87 i replaced upstream first too and code cam back very soon, after replacing downstream I run 2k miles... hopefully this injwctors cleanr will help. What milage you have? I have 180k

More than 2000 miles-still no codes, everything is ok

Possibly problem with air flow sensor. Clean it fist
Did you or didn’t replace the catalytic converters ? I also have p0420
Didn't replace it.
Do you have the part number for the O2 sensors
this is what I ordered:
Downstream www.partsgeek.com/review-product/1Y4V33DCPS6
Upstream www.ebay.com/itm/204338016551
I got the P0420 code. Replaced the sensor, cleared code, 2 days later code came back. Same for you? I dont want to replace the cats.
The code came back after 2k miles.

Just the upstream. Which I replaced Sunday. I used the cataclean but just this morning and code came on this afternoon.

I have 155K miles
20 bottles of cata clean, o2 sensors just a hundred dollars shy of new cat.
new cats thousands
