I couldnt find any articles/videos out there for changing the downstream O2 sensor on my 2007 Hyundai santa Fe. Error code was P0420.
Overall, it took me 2 hours total. The first hour was just making sure which part i was replacing and establishing a plan of action. The second hour was going to autozone and getting the socket set, removing and replacing the O2 sensor. I hope this video helps you decide whether or not you want to try this repair or take it to a mechanic.
Does the 3.7 V6 have 4 or these since it has two catalytic converters?
I need help i have hyundai veracruz oxygen sensor is not good Chek engine on
Great video; thanks!
Along with not showing how to get it out, you needed anti-seize on the threads of the new one.
@CJ Rich. CJ, what's the purpose of the cat further down the exhaust. There's no censor connected to it and since they welded all over the studs, I doubt I can cut the stud off then drill out the remainder in order to put new bolts on to it. I have to replace the front exhaust section and hate to have to end up replacing everything back to the muffler. I thought about bypassing that 3rd cat since there's one on each manifold. I have a 2006 Tucson which is about the same as the Santa Fe..
Two questions…Did you solve your 420 code or did the light come back on? Did you reset the check engine light with a scanner or did it turn off by itself after doing the repair.
Hello I have an 07 Hyundai Santa Fe 2.7 L engine V6 I got the code p2ao3 is this the correct video that would help me
Thanks for not showing us how to crack the sensor loose! Genius
It's a good video to know how to replace a oxygen sensor on your vehicle by your self. I just done my car from the dealer they charge me $364.79 for parts and labor plus diagnosis fee $130.00.
Bro good job…
I have a 2009, my mechanic says it has 4 O2 sensors. 2 upstream and 2 downstream. Is this true for the 2007?
But… is he a mechanic?
great job man…very helpful. My mechanic keeps telling me the Bank 1 S2 is upstream of the catalytic…but your part is downstream…so he is wrong
Ty. Nice going.
Thanks brother u helped me alot.
Have the same issue on my 2007 Santa Fe 2.7. Engine light on. P0420 code. Catalyst System Efficiency below Threshold. ( bank 1) I am going to try what you did and see what happens. Mechanic suggest to replace the catalytic converter and a 1000 + dl bill. Thanks for your post!
Thanks for those small hints great video
