Common engine codes that set when an oxygen sensor fails are p0135, p0136, p0137, p0138

[@nightfuryflame7366]

Thank God for this video

[@carcasscruncher9354]

@2:47 I do indeed have a drunk front wheel drive vehicle lol Good info though

[@guilateen]

Great tips. Thanks for sharing

[@FlatRateMechanic]

You are very welcome. Thanks

[@donttazemebro89]

Easy way to find cylinder 1 on v6/v8 is to see whatever cylinder is closest to you when you're standing in front of the vehicle looking at the engine. The cylinder closest to you is cylinder one and whatever side that is on is bank one

[@samg5543]

The firing order has nothing to do with the O2 sensor locations. I think you mean the "firing order diagram", which would also happen to show the location of cylinder one. The location of cylinder 1 determines bank 1, the other bank is bank 2, but the firing order is irrelevant in this context.

[@FlatRateMechanic]

Yes you is correct, that is what I was trying to say.

[@donadams3298]

I just watched your video and having just replaced both O2 sensors on my Hyundai 2.4L and I can tell you that there is no sensor located after the cat. Both sensors are located 12" apart just down from the exhaust manifold. You are not the only youtube mechanic that has said the Bank1 Sensor2 is located after the cat on a 2.4L, so, you're not alone, just FYI.

[@VolvoForLife850]

So what sensor is calculating the air/fuel ratio once it leaves the catalytic converter? 🤔

[@Steven-hx5zv]

Theres a o2 sensor b4 cat and after cat on 2.4l

[@syfodias-jedimaster]

After replacing both sensors to the check engine light come off?

[@dreadglizzy1027]

Did he say Cadillac converter. Anyways great video. Thanks for sharing

[@491607265]

2010 Toyota Corolla, code P0136, recorded Bank1 Sensor 2, replaced oxygen sensor after converter, 2 weeks later, error code P0138 recorded (also Bank1 Sensor 2), any suggestions

[@EvilTwin123]

I'm so confused now Which bank has the free toaster?

[@trini_boi2414]

I don't have a code but my car has 145,000 miles and no check engine light should I go ahead and replace the o2 sensors?

[@ronfryer818]

Not a mechanic , if it ain't broke , don't fix it

[@syfodias-jedimaster]

Code came out for sensor 1 now after fixing it, Code is now showing For censor 2 is that normal?

[@stevengarrad4725]

Strai to the point

[@recoveryafterlife2878]
