Emissions weird one

Hi all
I have check emissions fun in the dash at the moment and running out of ideas.
I hit some road kill a few days back thought I got lucky and could see no damage.
any way on the way back filled up and the light came on on the restart.

On the ramp and the only issue I could see was the lambda sensor wire had been pulled off its clip
so plugged in the code reader it said the sensor was dead. Replaced sensor and beeped out the loom still have light on.
code reader now says sensors all ok but still over emissions any thoughts?
