Engine mgt light?

[ant_wales]

Had a decat fitted last week and the engine management light has come on, what can i do to turn it off? Also will it cause any problems?

Reving has been perfectly fine and no wild idling.

thanks

unplug first lambda sensor or plug in a OBDII tool and clear the fault
