Volvo: Engine Management Light Constantly Lit, v70, engine management

Question
Ray, I have an automatic V70, 1999. The engine management light is on for most of the time, but does occasionally go out for days on end. An exhaust sensor was changed and the light went out for some weeks, but has now started to come on again. Is there any way to reset? Many thanks, Mike.

Answer
Mike,
There is not a way to just reset. You need to have the codes read and deal with the faults. When the car is fault free the light can be rest and will hopefully stay off.
Any time that light is lit there is a fault in one or more of the management systems.
