Check engine light - oxygen sensor gen3

[B-Man]

They were showing not ready and ~450mv on my last scan before unplugging them.

It seems to drive the same now as it did before unplugging them

@Fu Manchu knows of an advanced diagnostic company (TAIT?)
i think you need to hand it to someone who can diagnose it for you

I already paid to get it misdiagnosed I don't have the funds to do it again any time soon.

TAT. It’s a nationwide network of diagnostic techs. These guys are very different from just mechanics. Their expertise is in diagnosing network faults and data analysis. There is no guess work. They find the fault and give supporting evidence for it.
They share their knowledge with other members via a forum and via online meetings. They create their own tech bulletins to add to a growing data base of theirs.

Like guns for hire.

Get in touch and see if they can direct you to a TaT member near you.

Would be great if they listed workshops that are members. Helps direct customers to them and makes it easy for people to find someone.

Sorry bit delayed had a starter, gearbox and ring gear to deal with on another car! Finally got that sorted.

So the bloke I took it to is actually a tat member. There's 2 in my area and he is listed as one of them.

Did you end up finding the issue
As I have the exact same issue
Started off the same and is now reading readiness of no with 450mv on both sides
Iv done new oxygen sensors
Spark plugs
Leads
Coil packs
Injectors
Fuel rail
Gaskets and seals for manifold
Checked wiring
Changed pretty much every sensor in engine bay

Nope. I went back to the guy and he was going to look into it a bit but probably hasn't done anything. haven't had time to get back there and be a squeeky wheel!

Spewing I'll let you know if I fix the issue

if they never change from 450mv then they are not connected, that is there default open circuit value
