First, you can go get free code reading at any parts store (e.g. Oreilly,
Autozone, Advance). Buying an O2 that you have to splice is not practicle,
by the time it takes to splice, and get connectors and tape.
@unknownaccount99 I see bosch products fail,I work as a mechanic.Bosch’s
spark plugs cause missfires in Chrysler products including GM.
@SenorDennis is it the same car?
no need to buy a code reader–either take it to a auto parts store to get
the codes..my friendly mechanic will read my codes with his $700 reader for
free..fyi

THANX man god Bless you
Would faulty O2 sensor be reason for P0171 AND P0174 to come on for my 2000
Ford Explorer? I have not indication that anything is wrong with the car
other than the check engine light is on and I am getting these codes.

If your car has two catalytic converters, there will be 4. If you have one,
there will be only two sensors. When checking your codes, match these up.
Bank 1 (possibly right cat.converter if you have two. If you have ONE, you
will only see Bank1), Bank 2 (possibly left cat.co). Sensor 1
(upstream/pre/front o2 sensor), Sensor 2 (downstream/post/rear o2 sensor).
@wafrederick I very much doubt Bosch makes junk. Bosch actually invented
the lambda sensor in 1976.
how do ou know when its time to replace the sensor?
I have a 2006 Honda Pilot EX and the check engine light followed by the
VTM-4 light came on. I took to dealer (had an oil change and the TM fluid
changed) They had it on the scanner and could find NOTHING WRONG…so they
RESET it…but the lights are coming back on – any ideas on what I should
be looking in to?
Thanks man, just bought two new sensors today that come with wires, gonna
put them im soon, it’ll be hard getting under my 97 camaro so wish me luck,
you saved me a great deal of time and money
They do make off set O2 removal tools now cos access to these sensors is
ALWAYS limited. You have to be very careful spraying WD40 around the sensor
and VERY careful not to get it on the new sensor.Some sensors are take
readings from both the inside and outside of the exhaust You may want to
re-use the old sensor if the fault returns or do a voltage test using a
blow lamp so try not to cut the wires too short if you are re-using the
connector. Finally, make sure the crimps are heat resistant..
Thanks for sharing this useful info. Are these two suggestions good for
loosening any rusty item or specific to car parts?
Thanks for the video, I changed all 4 of my oxygen sensors on my 04 tahoe
just to be on the safe side!
does that effect, your car burning too much gas???
THANX omething wonderfuls The first time I can understand the explanation
you have used simple words and clear images and video was very clear
OBD Scanner or car computer scanner cost about 100 a 800 USD (according
sophistication level expensive models are able to check SRS “airbag”
status) before buy one check if your car have OBD or OBDC II OBD scanner is
useless in some car manufacturers (like Peugeot, Citroen or renault) =)
hello..i got O2 sensor.. malfunction on my toyota alphard…the new one
will be 160 usd/p there are 2 piecis sensor on my car…. i had offered by
used spare part shop thar only 78 usd /p with 1 week warenty… izit gud
value for money?shud i get the new or the used one…tq in advance for ur
opinion…
will an o2 sensor cause my truck to sputter when accelerating? If not, I’m
stumped..replaced plugs, cap button, distributor itself, wires, fuel
filter, fuel pump..please help
I disagree COMPLETELY. I don’t know a single person who can’t drive to Auto
Zone within 15=20 minutes…MUCH cheaper than a code reader even at today’s
gas prices.
That is very true. On my other truck I just purchased the OS with the
connector already installed and it was much easier and you don’t have to
worry about not getting the splice sealed up good. Thanks for your comment.
And autozone (and all the other shops with free testing) don’t have the
equipment for ealier model cars 🙁
Good review, thanks.
i have a P0430 code…if my o2 sensor is bad -would it throw a code for
that too…..would a lazy sensor throw a code?
excellent love video
would bad o2 sensors cause high idling and the motor to break up and be
very sluggish under throttle? also would it cause a car to not want to rev
past around 3500 rpm or so? if youve heard of symptoms like these and the
o2 being the culprit let me know asap
@chuasmare22 I just today paid $200 at my local shop for them to replace an
oxygen sensor.
Try to avoid splicing into sensor wiring. Just spend the 20 bucks and get
the connector. Once those connections start to corrode and impede the
signal flow, you will have nothing but issues with power, fuel consumption,
and false codes.
Not everyone has an autozone near them.
@a1nall No, you have something else going on.
Good point.. The fault code may give a clue or using a computer showing
live running data should give a better idea of how each sensor is
performing. Not all OBD2 compliant vehicles have that many sensors. Most
only have two..one each side of the Cat.
Hello,i really appreciate you posting this very helpful video.Thanks.Can
you please help me with replacing the oxygen sensor of my 2001 ex honda
passport?How many sensors do I need to replace and what type of 02 sensor
to use?once again thanks
