MOT Emmisions failure Rev3 Turbo!

[RandomDan]

Hello.

My OHs rev3 turbo has just failed its MOT on emmisions and iv been assured its the lambda sensor.
Where do i get this sensor from?
I can see the N/A ones around but im told they are differant.
My normal fall back would have been fensport but they dont stock much of anything for the turbo exhaust!

The Fail was on CO content at 0.58 natural idle and 0.49 fast idle.
The limit being 0.3.

Any help would be greatly apreciated!

NA is different, you're correct.

What you need is a Denso DOX-0217. Plug and play. Denso website will tell you 0215 but as my friend found out recently that's the US spec 4 wire sensor. Connector is different.

Sensor is ~£60-£70. Up to you to confirm it's definitely the right one, you can cross reference part numbers against Japan parts - http://www.japan-parts.eu/toyota/jp/199 ... uter#89465

Whereabouts are you Dan? I changed mine a while ago cos i thought it was knackered but i think i changed for nothing.
You could try it then give me beer tokens

Thats the correct one for a 205 GT4 according to Opie oils.

Not a bad price, I should probably replace mine as I get pretty xxxx mileage just cruising along the motorway in mine.

Under £50 is very good. I need to buy some oil but already have a new sensor... I paid close to £60!

[pbmr2]

last fail on the mr2 I had was because of a small hole in the exhaust system around the back box. Quite a small hole but enough to fail the test on emmisions. The hole wasn't enough of a leak to fail for that. worth a close look before buying a sensor in the hope of fixing it.

[SonicSW20]

Hard to tell without the full results but a backbox leak would not affect CO figures, it would affect the calculated lambda though. If there was a hole pre o2 sensor that would cause it to read lean and compensate by adding more fuel, which would increase CO.

O2 is simple enough to test with a multimeter though.

Or if you're happy to swap the connector yourself: http://www.ebay.co.uk/itm/1x-Denso-Lamb ... 2749.l2649

Just put one of these on mine; works perfectly.

[SonicSW20]

For the sake of a tenner I'd rather have direct fit tbh!

[Magic Beans]

I spent far too long trying to get a definite answer on which part no. to get. In the end I opted for the one I got and thankfully it worked. If I'd have known about that one I'd absolutely have spent the extra money.

Thanks for the offer but we have a new one on the way now.


xxxx know where all you guys found them though as the only one we could find was from MR2Ben at £85!
I know it expensive but you cant argue with the service and garanteeing to get the right one is worth it.

But Gareth gave you a link to the exact one? What a waste of money...you can get the firect fit denso one on ebay for £50.

I cant see any links to the right one :S

I wouldnt have spent that if i didnt feel i needed too.
Besides iv been burned before buying the 'right' part from som random ebay seller.

I posted a link to the one on opieoils which comes up when you choose the a 1995 celica gt4 which is the correct one for this car also.

yep simple to test, wonder why people don't before buying parts?

[RandomDan]

Well iv just had it re-tested with the new sensor and its exactly the same.

So next job to check the manifold for leaks?
Not a job im looking forward too!

It may also be worth me noting that the breather from the cam cover is quite loose and leaking oil and presumably air that wouldnt cause the problem would it?

Ill get a picture of the full emmisions run down ASAP for those intrested to digest.

Bloody old cars! xD

[SonicSW20]

What are the new figures compared to the old ones? Can you post photos of the emissions test result sheet for both tests?

[SonicSW20]

The Fail was on CO content at 0.58 natural idle and 0.49 fast idle.
The limit being 0.3.

Back to the OP as I've just clocked this...
What is your cars date of first use? *Most* Rev3 turbos have a higher limit. Any MR2 Turbo with a date of first use of 31st July 1995 or earlier has a limit of 3.5% CO, 1200ppm HC.

[RandomDan]

Hopefully this works, y first time using flikr since the photobucket incident.
I already hate Flikr good start.

ANYWAY

That is the old one.
The new results were much the same but the HC is a tad higher now.
I didnt get a print out for the latest test as they were doing it as more of a favour.

The car is a 96.
