Thank for the video! Question, I took off my old one and when removing it,
one of the nuts was damaged due to it seizing from heat (someone didn’t use
anti seizing compound)…Any idea what size the nut is? I’ve looked online
and found nothing…
I removed the two nuts but the sensor dont come out.
It hits the bolt,
The flange bolt is on the way, and in order to take out the bolt I have to
take the sensor First!!!
There are two ways to clear the check-engine light, the proper way is to
use a scan-tool to reset the diagnostic codes. Another method is to
disconnect the battery for a few minutes and force the computer to relearn
everything.
I’d recommend a Denso replacement. On denso o2 sensors for this toyota the
plate is already attached which means you don’t need an o2 sensor socket.
Denso also made the original Toyota sensor.
@gromit190 TPS sensor sometimes does it, check it first before replacement
I just replaced my corolla’s o2 sensor using this video and didn’t feel
like I had any problems but now my car is running strangely when it wasn’t
before. It’s hesitating when I hit the gas and fluctuating in power while I
drive. I’m not sure what I could have done wrong as the process seems
pretty straightforward. What did I miss?
Also you could have screwed the sensor into the plate and then install it
in one piece.
@DMoneybags82 This particular one is the upstream, and the 2003 Corolla
should be in the same location,, or very close.
i have a toyota corolla 2001 and is reading a P0171 CODE… a friend is
telling me is the air flow sensor,taht i need to changed??
Thanks, We do not have a downstream o2 sensor video on one of these cars at
this time. But the procedure is not much different than what you see in
this one, you should be able to follow the same basic instructions shown
here and use that info for the downstream sensor. Good luck!
It was on mine too. I just pried that bitch out with a screwdriver. The
bolts not bent, its just in the way.
I have a Corolla 2002 CE 1.8L,recently i changed catalytic converter and
post cat oxygen censor ,But still shows PO141. some days it turn on “engine
check light” some days it go off .What could be the reason
the P0135 code is a bad Heater Element on Bank 1 Sensor 1, Which means the
sensor closest to the engine, (usually just before the converter).
Great video! Thanks
Great Video, I got a question, for my 2000 Corolla, got code PO 172, rich
in gas, do u suggest to replace the upstream O2 sensor? Thank you.
i have a toyota corolla 2001 but when i try to start the car its delay a
lil bit, how can i fix it, because in the computer it was showin that it
was the oxigen sensor but i change both and the problem is still there,
what can i do to fix this?????
You can get to it without removing the exhaust manifold. Remove the heat
shield plate. You will need a “flip-flop” socket attachment and long
extension. Hopefully, you have small hands, too. Plus, lay a towel over the
engine. You will be laying on top of the engine to get to it. Might take an
hour or two, but be patient. You’re saving money not using a mechanic.
Hi, is this a front or rear oxygen sensor? My Corolla failed emissions test
and need to replace O2 sensor and I’ve seen there’s two types of them:
front & rear. Any idea which one to replace?
The one before the catalytic converter is always considered the upstream.
This is very informative, but I have few more questions. When do you change
the oxugen sensor? Which one do you change the up stream or the down
stream? Looking at the video, can the sensor attach first to the adapter
before?
It could be the mass-airflow sensor. The PO171 code means a “System Lean”
indication, which can be caused by the mass airflow. The most common thing
that causes a PO171 is a vacuum leak though, make sure you check all vacuum
hoses and fittings for any leaks.
I suppose it’s a personal preference, but I prefer to put the plate on
first, it just gives you more free room to manipulate the small nuts while
getting them started on the studs.
Even after the o2 Sensor change
You didn’t need to crawl underneath the car.
Thank you for this video. Very informative. Question – Have you posted the
video on replacing the downstream sensor yet? definitely need that for my
2002 toyota Corolla. thank you !!!
Very helpful and easy to follow. Thanks a lot.
Thank you .
I got a 2000 ve and when I tried to change to 02 there, the exhaust
manifold bolt was blocking it from coming out. Is there another way around
it or do I have to get the exhaust bolt out first?
For 2001 Toyota Corolla’s, MAF Sensor is often the problem. Less than 10
minutes to fix, screwdriver, MAF spray (you can find youtube videos for
this). But it’s very easy to do. Then disconnect your battery for 10
minutes or so and see if it works. Also, a noticeable problem if you keep
getting the gas cap problem..
I am sorry but I do not quite understand your question. The o2 sensor we
used included all the parts needed for the replacement of this sensor.
i have a 2002 echo code po135 bank 1 sensor 1 is that the one on the cat or
the one post cat thanks any info
The 1996 is actually different, the exhaust manifold is on the front of the
engine on your car. But this actually makes getting to it easier. And yours
does not have the flanged adapter on it, it’s just a standard screw in
style.
