Good day everyone GarageKing here and today I'm going to show you how to
change the rear oxygen sensor in a 2013 to 2017 Toyota rav4 with a four-cylinder engine
Now from my research, and from watching some videos, what I have seen is all the
other rav4s that I've been watching or trying to figure out have a whole bunch
of oxygen sensors under the hood. This vehicle only has one, so there is two in
total in the vehicle, one is in the exhaust manifold, and one is underneath.
That's it the other videos showed a bunch so the vehicles just they must be
old videos, older model vehicles, but anyway on the 2013 to 2017 this is how
it is let's take a look underneath so we're underneath the vehicle right now
you can see there's the front of the vehicle now if we follow it back right
around where the rear subframe is right there we can see there is our other
oxygen sensor so that's it so there's just the one under the hood that I
showed you earlier and then there is this one so let's get a better look at
this oxygen sensor I took off the passenger front wheel and we're just
gonna pan in here we're gonna take a look around we should be able to get it
I think from the wheel well there you go there it is right there so you can see
it's it's right there so either we'll get at it from the bottom or we'll get
we'll get at it from from the side so one way or another or worst case
scenario if it's really stuck in there and I can't get a tool in there we'll
take out the pipe. Okay so it's super hard to see how to undo this connector
here so here's the connector here and I was able to unclip it from the
intake manifold on the back so just to show you what it looks like the easiest
way was to put a set of needle nose in there and just squeeze these two tabs
and then this way I could pull right out and actually there you go!!! Blooper here,
we go let's see if we can get some light here's what it looks like in the back I
don't even know if I can show you this because I don't know if I can even get
the light in there too show you and I don't think it's gonna
maybe kind of okay okay yeah so there we
go there's where it was clipped you can see
the hole and I just used pneumos pliers to take it out so anyway and then we're
coming up through the wheel well here so yeah the easiest thing to do is to
unclip it and then now what we can do is we can just separate it here and then
we'll clip it back in and then clip it back to the intake manifold so it is
unclipped in now it's just a matter of unscrewing it from the exhaust I think
we're gonna have to heat it with the torch because it is too tight
there you going it is loose. Okay and I just took out the o2 sensor I still have the
tool on it, is really hot so don't touch with my hand as you can see we use the
torch just to loosen it up a bit to get it out but anyway there's our o2 sensor
again the new here's the new oxygen sensor we see it actually comes with
some anti-seize on it so that is awesome if we look at the specs here it says
for metric 18mm, half a turn after finger-tight and metric 12mm is three
quarters of a turn this one is a metric 18 thread so about half a turn after we
just can do it by hand enough and that will snug it up good. A lot of people put
these in way too tight they actually don't even have to be in that tight
because as you saw I needed a torch to get it out so there we go I'm actually
going backwards just because the way the cord is here to make it easier for me to
start threading it in there we go so I can push this up this way that's just
the wiring harness one there we go yeah there we go
it's in yeah we're just gonna give it a snug up so we said about half a turn so
I can see on the bottom I've got a white wire right on the bottom so that white
wire that I'm looking at should be at the top when I'm done and I can tell
that's all I need, actually any more than that, that's all I need I didn't even
need that much, that's all it has to be it doesn't have
to be that that takes so so there we go so oxygen sensors now we know we can
plug plug the harness back together there we are there's the two pieces so I
will connect them back together and then just pop it back up to where where
connects at the intake manifold okay yeah there so there it is you can see
source for the shadow lady and then it's connected right back up up there so
that's it there back back connected okay so here's the
tools that I've used let me explain so we have our oxygen sensor socket it's
7/8ths, and then also went back and forth tried with this one this one's
different clearance but same size 7/8ths but your oxygen sensor socket
will do, I use needle nose just for the connector as well as a little
screwdriver 7/8 socket there or sorry seventies wrench just to put it in and
then you just need a ratchet now if you don't have access to oxy acetylene torch
most people don't you can always use a benzine torch like something like this
you just screw the top on and it be actually worked not too bad definitely
not as good as oxy acetylene torch but but it'll still work
so hopefully you enjoyed the video if you learned something I really hope you
did, any questions comments or concerns please leave them below I would
appreciate if you consider subscribing that's it GarageKing over and out, we'll
see you on the next one thank you :)
