yaris engine check light keeps coming on

[mattuk10]

i have a yaris t sport 2002 and recently the what i think is called the engine check light keeps coming on . it has done it since i owned the car , every couple of months it comes on for a day or two and then goes off. but recently it keeps comin on a lot and comes on for a few days , but sometimes a few hours then goes off , there doesnt seem to b anything wrong with the car it runs starts fine etc , could it be a dodgy sensor ? what makes the sensor come on anyway ?

thanks in advance sorry if this has been posted elsewhere or is in wrong section

do you have the code for the CEL?

could be the catylitic converter....goes away once the car is warm....?

stop by Auto Zone, they will read it for free, or buy a code reader from Auto Zone or any similar car place and read it yourself.
