How to Replace Oxygen / O2 Sensors On Your Car

about and today we're going to be looking at replacing the ultra sensors on your car we are looking at a two thousand you bring your today reports these their steps work with pretty much any vehicle uh... that still the tools they need are very simple pre much if you can change ur well you'll be able to replace the epicenter your card issued at objects and expand few wrenches uh... it's a common failure uh... usually it if you see this uh... check engine light kuda p zero one six one p zero one four one listen to that have on this vehicle for the two rewrote his answers that'll indicate that that he wrote the center's combat need to be replaced but of course birth report said it you know there's a quote the wiring make sure that you know capital a break in the wire or the wires has a rubbed up against some uh... some insulation were uh... a heat shield or exhaust header where the catalytic converter that's about it could be a grounding issue i'm so it wasn't always straightforward but most often values and replace the sensor disaster itself is usually pretty affordable as fifty dollars it novel zona riley's and uh... the job itself usually takes less than our assuming that the though to censors come out easy sometimes they can be able to lansing if it's a you know from the factory sensor has been there for the last ten years it can be very difficult to get out slightly exhaust a exhaust alters let's take a look at the vehicle here we are on the vehicle mhm here's the thing from the vehicle the engine transition handwriting from us we have and it catalytic converter and we're looking at the passenger side uh... on uh... the motors there's typically to banks of uh... i'll go to sensors a one four a three-sided on our waiting in line motor there's usually just uh... there's one bank and then uh... every modern uh... automotive uh... system has uh... to can deliver a two oh two centers one before finland after the catalytic converter luxury unit there you can see here's the uh... the front sensor passenger side and the uh... the rear sensor on the passenger side uh... again i have a uh... p zero one six one lp zero one four one on this vehicle which indicates failure of this rear coach you censor on both sides so the very first they were going to the infant threatening her liquid wrench and uh... irrigate that real good course materials and that i protection on time and what that soak in for a while while you run down these wires and that is next if you're in a follies lawyers back and disconnect them and after looking at the passenger side of at the close look at the driver side in you can see the uh... they refuse that through there and the character of the site is extremely accessible so here's what those connectors look like this is what feared the intellectual like electorate is appreciated a is uh... generally likes his little uh... uh... protocol on connector arrest urs here that stop it from from coming up like a little boy pre easily the orbital informed on its own and sometimes it can be a little all stubborn sometimes they come off real easy it's been really careful deliberate attempt and there's and now we are ready for you figure wrench to the sensor itself and here's a view of of the passenger side connector from the writer is extremely hot spots will be on the streets right back there hanan quote that connector and here we have a right at the most challenging part of the task and that is arguing that what you sent your loose and mentioned the uh... the first step here if we worked on the waiting list for recently karenge on there that always helps some people recommend uh... will reappear caller your uh... near catalytic converter and all that will get very warm might help the pocket and there and uh... for me uh... i'll just use the socket with them ale one could break the law and that proved to be to test with kulbir elbow grease uh... pretty much old though she sensors use a twenty two millimeter socket you can get they specialize socket or reg from uh... they auto parts store which uh... which may or may not be a good investment for you in my case i was uh... westerners then abruptly senior thesis readin seeing initial wiring war of the connector anything for that sort so i just want hadn't cut the wires off the top tier two sensor so it wasn't arguable socket on there as you can see the way that it's designed with the catalytic converter right here if there is just enough clearance built into it to use and evil socket aura more specialized uh... which you sent your socket we're getting a wrench in there can be actual more challenging martinelli conflicts here and you're something like that uh... xem me may need to use a rancher adjustable wrench well i would recommend an adjustable wrench and mattel child like this in my case it was just a a a breaker bore in the standard ewbal socket and after a little tonight along with uh... just a ratchet on that same socket we will do uh... yet the though to censor outside here's our quarry laying in bed focused on this close and uh... the other side should be all these units i mean you're here you go about doing to just the one uh... this guy does look a little of were worse for wear means institution is looking at it uh... until you do me a little too just or something like that but uh... completion of the sensors are the caused fill your head uh... reassembly is a allot easier as it newly is that these things uh... you know i think you wanna make sure it is to uh... put some anti season there when you reinstall the new coaching center so that uh... extend it for out they come out nice easy hopefully anyway uh... but just uh... insert that uh... then you go to censor him tight-knit men came in with uh... with that same rach interesting use connect sensor and then uh... clearly codes let warm-up and hopefully you won't see that message check engine light anymore if you have any questions feel free to oppose on the video and all do whatever i can help
