Spartan 3 lite wideband

Hi all
I have a spartan 3 lite wideband connected to a ms3. Installed in april and everything has been working fine while inhave been getting to car ready to be roadworthy again.

I went for the test yesterday and it all passed but i came home to start auto tune and the o2 reader will only read 16.7.

With the sensor out in free air. The sensor warms up, the led is showing as correct but it still only shows 16.7 even if using lighter fluid.

I havnt checked the voltage as it means i need to take everything apart.

But it looks like i can try to clean it with petrol. Are there any reccommendations on this?

Thanks and sorry if i have missed something.

Right. So after speaking to toalan. I was sent a replacement.
No further information was given as to if it was a full module and sensor replacement.
I asked if it was ok to try to change the sensor first, or what may have caused the issues so i can try not to replicate the issue.
The replys back were not overly informative and as I had a ‘sure’ back regarding the sensor changed first, i presumed it would be both parts.

The invoice for the items were a few days over 3 months, but i had to wait for delivery.

I recieved all the ups part numbers, have waited close to 2 weeks for the parts to arrive, o ly to find the control module

I have then spent over 6 hours re routing the new module to have the same issue.

I had issues with innovate so moved to another option, only to have the same issues.

Currently the money spent on both these options would have gone a long way to a proper rolling road.

Sorry, feeling a bit sorry for myself at the moment as i cant make progress
