How to reset HEGO / HO2s / Lambda sensor adaptations?

[djsall]

Hello!

I need to reset stubborn HEGO / HO2s / LAMBDA sensor adaptations in my vehicle.

It's a 2018/9 Ford Mondeo MK5 with a T8CC Duratorq engine.

It was driven with boost leaks for a long period of time and the PCM mislearned HEGO behavior because of it. There is no service procedure in my forscan to reset HEGO sensor adaptations.

Is it inside the beta or do I need to go to a garage / purchase another tool?

Best regards,

When you delete the fault codes in a Ford it resets all the system checks. You can also reset learned values in FORScan or just pull the pcm keep alive memory fuse out for five mins then put it back in.
