You are right about the original manufacture part, i had nissan veihicles before, a sentra and frontier as in the video, tried autozone or after markets just to found out that i got an error code again after some time and stalling issues some times, thus making me spend time money and effort, and forcing me buy the nissan original part as i have to do from the very begining so far, lesson learned for me. Some times it is not worth to save some few bucks while spending hundreds.

I live in a state with no emissions inpections (SC).03 Pathfinder p0430 came on a few times and I reset it a few times before trying seafoam.I ran seafoam in the gas and did a full upper intake clean and then ran the crap out of it on the highway.CEL p0430 did not come back on until almost a year later.If you are on a budget or just need to pass emissions it is worth a shot for $12 worth of seafoam.

Thank for the video. It helped me figure out which side was the 430 code since no one at the auto parts dealer shops knew the difference. However, the guys there suggested that I run some 91 gas and sea foam first to see if it's throwing a code over dirty gas. I did fill up with 86 in a small town in az on a trip to save some money. :(. I reset the codes and it hasn't come back on. However, if it does- I will certainly follow your advice about the converters. I figured they were all the same quality. Thanks again!

He's right about aftermarket converters.  Aftermarket parts, especially sensors,  have gotten so bad in the last few years. It's awful.

Good video to help me with my 0430 code. May I suggest that instead of using terms "left" and "right" you refer to the driver's or passenger side? Not sure if you mean "left" as we are viewing the video or "left" as we sit in the vehicle. Thanks.

Replaced the Catalytic converter on my 2015 Nissan Pathfinder at Nissan with Nissan parts. Just 20days over a year I have the same code up. The first replacement wasn’t cheap.

I fixed a p0420 code with the cheapest aftermarket cat I could find on Ebay about 3 years ago, still working fine. I just got a p0430 and will get another cheap cat after verifying my O2 sensors are in spec and checking temperature of exhaust pipe before and after cat to see if its clogged.

I have a 2013 Nissan Frontier SV V 6 with 97, 000 miles and got a P0420 code. After looking at the cost of OEM catalytic converter for the right front converter I was shocked. With the truck being over 10 yrs old I am weighing the cost on OEM or aftermarket the difference is about $1, 000.00. The used catalytic converter alone would bring about $300. - 500 at a scrap dealer.

Yup I agree. Put in new front cats in my 06 Xterra with aftermarket cats. About 1yr later p0430 is throwing again. Good thing I can afford a OEM cat, thanks for the tip!

Great Video, I have a 2011 Nissan Frontier Pro 4x that ive had issues with the MAF sensor, the original one died and put my truck into limp mode, i replaced with a aftermarket one from o'relieys and kept throwing the code a short time later, i took it back under warrenty and they replaced it with another which does the same thing, so figuring maybe were they were aftermarket i decided to get another off amazon, the reason why Nissan want $340 for a oem sensor. So have you had issues with these trucks not liking a aftermarket mass air flow sensor? thinking i may as well go ahead and buy an oem from nissan. What are your thoughts?

get a sparkplug non fouler from local auto parts store, bore and grind open to fit O2 sensor and install downstream to block theses nuisance P0320, P0420 codes!

You should also take into account what caused the catalytic to go bad before putting a new one especially if it went bad way before it’s expected life span

Informative Video. Thank you for posting. Question...how do you rule out the downstream senors? If a senor was going bad what code would it kick?

I just recently got a refurbished engine and about 15 minutes later the check engine light turned turned it on? Any ideas on what it can be

Are these converter locations the same as an 04 or no? I have both a P0420 and P0430 code on my 04 Frontier
