Barely been at home recently and when I have I've not had any car time

After what feels like an eternity I've identified and purchased what should have been the correct lambda sensor for the car.

So much contrary information out there, on what is and isn't compatible with a Rev 3+ turbo engine.

Add in that the old info out there references parts that are no longer made/relevant!

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:

Old one out.



Seen better days!



New sensor wired up

(somewhat over-engineered I might say

) and fitted.



Fired up the engine.

throwing a code 21!

Now at this point I'm wondering if it's:

a) the sensor isn't compatible

b) it's the wiring is bad

c) the ECU hadn't been properly reset

(despite pulling the fuses etc)

d) the SARD ECU is wrong in some way?!

Logically the wiring should be correct, it was triple checked.

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.

So I decided to try a different way of resetting it, I pulled the battery for an hour.

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

(god I love having that!) and was presented with a constantly flashing engine light.

Now I'm a bit rusty on codes, so at the time I was a little worried.

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.

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
