Barely been at home recently and when I have I've not had any car time
![](./images/smilies/spacer.gif)
After what feels like an eternity I've identified and purchased what should have been the correct lambda sensor for the car.
![](./images/smilies/spacer.gif)
So much contrary information out there, on what is and isn't compatible with a Rev 3+ turbo engine.
![](./images/smilies/spacer.gif)
Add in that the old info out there references parts that are no longer made/relevant!
![](./images/smilies/spacer.gif)
Eventually though this was ordered and promptly delivered.

£38 off eBay, which is less than half the cost of the ones with the relevant Toyota plug on.

Plus I wasn't always convinced that they were the correct unit either! Anyway, here's the link if anyone's looking for a replacement:

New sensor wired up
![](./images/smilies/spacer.gif)
(somewhat over-engineered I might say
![](./images/smilies/spacer.gif)
) and fitted.

Fired up the engine.

throwing a code 21!
![d'oh! #-o](./images/smilies/eusa_doh.gif)
Now at this point I'm wondering if it's:
![](./images/smilies/spacer.gif)
a) the sensor isn't compatible
![](./images/smilies/spacer.gif)
b) it's the wiring is bad
![](./images/smilies/spacer.gif)
c) the ECU hadn't been properly reset
![](./images/smilies/spacer.gif)
(despite pulling the fuses etc)
![](./images/smilies/spacer.gif)
d) the SARD ECU is wrong in some way?!
![](./images/smilies/spacer.gif)
Logically the wiring should be correct, it was triple checked.
![](./images/smilies/spacer.gif)
There's no mention of the SARD ECU causing this type of issue and the sensor itself did fit and is supposed to be universal.
![](./images/smilies/spacer.gif)
So I decided to try a different way of resetting it, I pulled the battery for an hour.
![](./images/smilies/spacer.gif)
I've had to wait until today to test it.

Fired her up, didn't check for codes etc, went for a long drive so she was nice and hot, came home.

Flicked the magic diagnostic switch
![](./images/smilies/spacer.gif)
(god I love having that!) and was presented with a constantly flashing engine light.
![](./images/smilies/spacer.gif)
Now I'm a bit rusty on codes, so at the time I was a little worried.
![](./images/smilies/spacer.gif)
Google soon put me right though, with that meaning there were no recorded errors!

This is pleasing!

TL;DR If you have a Rev 3+ turbo and need a new O2 sensor, go spend 38 bucks on a DOX-0101.

Took delivery of a parcel from massbasshunter the other day.
![](./images/smilies/spacer.gif)
If it stops raining and I get a moment I'll fit them.

Pretty much the only eternal tweak I'm planning on making, but one I think will finish the look off nicely
