Toyota Yaris Downstream Oxygen Sensor Replacement (P0606 P0138 Codes)

[@stevenmeyers5088]

Heads up! Just did this job and found out the center console trim is super easy to remove. One bolt in the back most cubby. Once removed, accessing the sensor plug is very easy to access. No need to remove the seat. Maybe that is covered in the video, but watched it a while ago and wanted to share.

[@Bootstrappin]

I didn't cover removing the center console - this sounds a lot easier! I'm gonna pin it.

Just did this job yesterday on my 2012 Yaris SE. It was giving me check engine with codes P0138, P0139, P0607 (control module!). Your video was key to giving me the confidence to try this before letting a mechanic replace both the sensors and the engine control module. I did spend an additional $30 to get an oxygen sensor socket from Autozone to get the sensor loosened up. At the same time that I did the sensor I also cleaned up my Mass AirFlow sensor (MAF) and changed my filter. All of these together with using my OBDII reader and erasing the old codes once fixed the problem. It's running smoother and no check engine light. Thank you!!

Great work, this video is very helpful. Just worked on my niece car. She went to the shop and they quoted her $480. Rediculus price. So I went and got the part at Oreily and it’s only $90.99. I out it on my self.

[@davida871]

You were right on the money. I originally had P0138. I cleared the code after installing a new battery. Next day went to start car and check engine light came on with P0606 code. Replaced rear O2 sensor and cleared code. Hopefully this fixes it. O2 sensor was white when I removed it. Used Denso copper on threads. Great video. That harness was a bugger to unhook but did it thanks to your video.😊

[@Bootstrappin]

Awesome! Seems like that'll be the ticket.

[@bobnevala5218]

Thank-you for taking the time to make this video!

[@markshort9098]

I was always taught to remove the negative terminal first and put it on last to prevent power spikes to the computer

[@swalker6911]

Thank you thank you thank you. Yes entertaining but it saved us from paying big bucks at the garage. We took us a few days. Grateful to you. Blessings.

[@CNArea51]

AWESOME Thanks for all the details... You made the job very easy for me

Spot on! code po136 and po137 o2b1s2 rear.Thank you 2012 yaris sedan

[@brettbodybuildergfvv]

Awesome video. Thank you so much. Quick question. My wife has a 2007 Toyota Yahirs with 187000 miles. She had the engine light come on. We got her vehicle scanned. The scanning tool is saying fuel sensor of some kind. Do have any recommendations? We don't want to spend too much money on the problem because of the age of the vehicle. My wife is a school teacher and needs her car. I let drive mine. But need two cars. So I can go to work and school.

[@Bootstrappin]

Sure thing. What you're saying is vague, I'd need the actual code to offer relevant suggestions. Going out on a limb though - if it's a P0191 code, this article may help: www.700r4transmissionhq.com/p0191-toyota-yaris/

[@tommyd6665]

Can that same sensor go bad without throwing an engine code??

[@nismoskys]

Sweet video. Super helpful thanks

[@gabrielemorse]

sorry man, I've to put a cleaner spray in the oxigen sensor (sonda lambda in italian) upstream of FAP (or DPF). Is the one you're replacing, where I have to insert the spray's cannula? Is it before or after the Anti Particulate Filter?

[@Bootstrappin]

Sorry I'm so late replying, had a hard time understanding what you're asking. This is an oxygen sensor, I think what you're talking about is a MAF sensor (Mass air flow sensor/debimetro). This sensor is after the air filter, I have a video on how to clean the sensor here: kzbin.info/www/bejne/gZnLeoNpp5V1oLs

[@smhbukhari]

Hi there mate, My yaris give check engine alarm intermittently, any advice will b highly appreciated

[@Bootstrappin]

When the check engine returns, read the code with an OBD 2 scanner

[@mohsinrasul8450]

if the engine light continues to show after replacement - does the code need clearing?

[@Bootstrappin]

Yes, or driving a certain distance/time without the condition should clear it (provided the problem is gone)

[@mohsinrasul8450]

@@Bootstrappin Thanks for the information and the kind reply. I had it checked out and the mechanic said it was a result of poor fuel. hence the oxygen sensor lit up it's cleared for now and ill see if it shows up again.

[@kingmk7054]

@@mohsinrasul8450did it show up again

[@josenovoaperez4188]

Did the code ever come back on after driving it for a few miles? I have the same issue on my 07 Camry

[@Bootstrappin]

Didn't come back - at least not for the 10-15 miles I tested it. Sold it since though, so I hope it's working out for the next owner!

[@dfls5069]

@@Bootstrappin how long do the 02 sensors last on these Yaris ? Does the upstream 02 Sensor clog up too ? You could have saved a couple of $$$ and maybe cleaned yours... don't know how fouled up it was... what year was your yaris ?

[@DevinNixonDavis]

You think this would be the same for a 2016 Toyota Yaris

[@Bootstrappin]

Probably quite similar. You'll know for sure when you lift your car.

[@swalker6911]

Yes. Video helped us with 16 yaris. We took apart center console to get at it. Seat can stay. So grateful for video. Great job.

[@jamesbottoms2903]

Why not just cut and solder new sensor to old wiring?

[@Bootstrappin]

Totally valid method, and probably saves time. I personally think that's a little janky and try to avoid it as best as I can.

[@Marcel_Audubon]

I've been bippyless since I bet my sweet one once in the '60s and lost the bet 😬 Sock it to me!

[@Bootstrappin]

This is so sad, 1 like = 1 bippy to give Marcel the closure he deserves

[@felixtremblay3627]

Yeah that or just remove the center console with 2 clips and a 10mm bolt

[@Bootstrappin]

That probably would have made the job much easier lol

[@aaronstodolka3438]

Very entertaining I have the bank 1 sensor 2 problem. Nothing A 22 mm socket and some viagra can't fix.

[@Bootstrappin]

I am cautiously intrigued!

[@squezary]

So what do we do when we replace the sensor, and the wirings fine, p0138 still comes back?

[@Bootstrappin]

Could be a variety of things. Is it an OEM sensor? In my experience aftermarket doesn't tend to perform so well. Beyond that, you might have an actual condition the sensor is detecting - running rich or lean. Try cleaning the MAF to start, and check your air intake filter for clogging. This might help further: kzbin.info/www/bejne/gZnLeoNpp5V1oLssi=XAJ1jdgHyhhYCrB4

[@squezary]

@@Bootstrappin it's a brand new Denso sensor, the air intake is clean. I might try cleaning the maf, and yeah it's running in rich condition.
