Yaris 1.33 2009 Exhaust Manifold Lambda Sensor

[Narbar]

Hello!

 

My car has threw up code P2196 and after googling it, it looks like oxygen/fuel sensor one which I've read is the lambda in the exhaust manifold.

 

Please may I ask if you agree with my findings, but also the part to order as I've seen a few posts on people ordering the wrong sensor.

 

Any help will be appreciated, thanks Dean

It's B1S1, Toyota call this air/fuel ratio sensor. Is this for a 1.33 ?

1NR-FE - Denso DOX-0510

Hi thanks for the reply, yes it's the 1.33 🙂

[Narbar]

Looking at eurocarparts where that sensor listed above is for sale for £150.  But there's a denso one for sale for 85 which also says exhaust manifold.  Will that just be the wrong sensor or just not as gd?

[flash22]

Had a quick look £85 is b1s2 post cat (after the cat)

Denso DOX-0510 should be around £110-125 eg. https://www.ebay.co.uk/itm/162504565308

only other brands i would touch is NTK, Blueprint, Febi or Bosch

Just as an aside to this, does your car burn much oil? as I am wondering if the original reason for failure could be down to that (if it does burn oil).

[Narbar]

Thanks for the replies, I've not had the car long so not sure if it burns oil.  It has full service history but only has done a few thousand miles a year for 8 years.

 

I'll keep a eye on it

[Mooly]

OK, fair enough. Do keep a check on the level though.

[Narbar]

If it burns alot of oil, is there any solution other than new piston rings? 

[Narbar]

So is the DOX-0510 the sensor type? Or the denso code? 

 

Have euro car parts stopped doing there big 50% off sales they always used to do?

You have the numbers from flash. Denso DOX-0510 
 You can use these for best prices on eBay or Amazon. Also Eurocarparts has another cheaper prices website and with discount code comes to £117 https://www.carparts4less.co.uk/basket 👍

Not that I know of. There are lots of suggestions on the web but all lack documented evidence that that anything is successful or long lasting.

The problem with piston rings and oil consumption has another consequence that the only way to fix is a physical repair. Because if the oil control rings got stuck the excess blow by will polish the cylinder walls to the point that even if you manage to get the rings unstuck the walls will not be abrasive enough to make oil stick on and it will be burn again. Only way to stop that is , opening the engine, pistons our and properly cleaned, new rings, very important proper honing the bores , new gasket and put back all together. This is not a super difficult job for someone with experience working on engines, however there aren’t many garages that do that in uk. Here common practice is replace the engine with anonymous used one and you may end up even with more problems afterwards.

tbh oil burning is on higher mileage cars, you will soon know if it's burning oil

Oil Consumption TSB - EG-0095T-1112

 

low miles with lots of low speed, short and stop/start journeys plus it's 14 years old - you will get some failures eg. o2 sensors, Don't buy cheap o2 sensors unless you are getting rid of the car

I read somewhere a Toyota supplied short motor (block, crank, pistons etc all ready built up) was the only recommended repair route for these. I guess that would be the dealer approach anyway.

I think that was for the AD-series engines; IIRC the fixes for the 1NR-FE were just stronger rings and new pistons with more/bigger oil holes or something.

The car care nut recommends that and make sense of course. But that’s when the cylinder walls are scratched. He also uses strobe camera to inspect before opens the engine.

It was Piston, rings and rods for the 1NR

TLDR.

The most famous and mass problem of 1NR-FE - is excessive oil consumption, which often appears at mileage substantially below 100 thousand kilo meters. The reason is traditional for Toyota - the piston rings stuck. The need to replace pistons together with the conrods does not allow to renew the engine cheaply, but at least the cylinder block reboring is not an obligatory option.
The problem of oil consumption was recognized and described in TSB EG-0095T-1112, some production changes were implemented in early 2013. In addition to modified rings and pistons (with conrods), the valve cover and oil nozzles may have to be replaced.

Also the car care nut is US based, US market yaris had the 1.5 only (1NZ)

[Mooly]

On a 13+ yr old car its not going to happen (lol) at least not for me anyway. Goodness knows what the cost would be and I always wonder 'would it ever be the same again'. You would want a decent warranty on any such work.

I wonder just how many 1.33's are starting to fail MOT's now.

 

[flash22]

£2-3k parts and labour but tbh, it's an engine swap job but more than likely not worth doing if paying a garage

[Narbar]

Yes I only paid 1600 for the car don't think I'll be doing that 😛 anyone know the size of spanner required to get the manifold lambda off? Gonna just change the sensor for now and hope it lasts a few years

Pothole it’s 22mm. Best to see where the sensor is located first and how much space is available around. Then look for lambda sensor socket Toyota on eBay or Amazon and choose the most suitable. Something like that for example https://www.ebay.co.uk/itm/154933883242?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=dG-T29hnRXe&sssrc=2349624&ssuid=p34UK1z2T4m&var=&widget_ver=artemis&media=COPY
