Technical Any ideas for Fuel Fault

[Adam1984]

Hello.

Can anyone help and advise on what could be causing the live data tests am getting with the fault - OL Fuel B2?

What should I check and is it possibly an easy fix?

Thanks

OL suggests something to do with it going Open Loop. Most likely then is something amiss with the O2 sensors so it's running a bit too rich or lean as a result.

That said you can get odd little faults like that in generic scanning equipment where it senses something at start up etc. Get it hooked up to a copy of multiscan for a product specific perspective.

So you think it could be a oxygen sensor fault?

That could be a fault for whatever system you are using to read live data.
Is mil on?
Any obd2 codes?

They'd be the first guess for something being wrong. It could though just be one of those transient non events though as well if the car is driving OK. Live data can show up all sorts of stuff that doesn't matter really.

I have no codes. And no engine management light on.

Then you are most likely looking at a "fault" with system being used to read data , such as engine not running or not at correct temperature etc.
ie not a "fault"

A cold engine will always be in Open Loop. OP should use the scanner with a hot engine.

As I said in another post, a code scanner in the wrong hands can lead to mis-diagnosis. Don’t assume they’re always correct, and spend a little time seek out the ‘cause’ before deciding anything’s wrong.
