PLEASE HELP ME TURN THIS LIGHT OFF!
 

i was taking a loose heat shield off from underneath my 1994 wrx turbo and it wasnt budging. i smacked it off with a hammer but in doing so, i accidently smacked the lambda sensor (the one that sits in the exhaust manifold) and subsequently damaged it. as i got back into my car and started it, the cat light switched on, on my dash.

i have changed the lambda sensor for a new one, but the light is still on.

have i done anything wrong in diagnosing my problem?

somebody told me that the ecu stores this error code and needs resetting, but i dont know.

please can somebody help me in turning that cat light off....:Whatever_

Try taking the battery off for 30 min that should reset your ecu there are other ways but you have to drive it
