What code is it?

you have to use a code reader to reset the code. it will not automatically reset just because you changed the parts. advance auto will help you clear the codes. o'reilly will only help you read them.

NO I REPLACED THE 02 SENSOR AND CLEAR THE CODE WITH MY CODE READER IT WILL CLEAR BUT THE CHECK ENGINE LIGHT WILL COME BACK ON LATER REREAD CODE AND THERE NO CODE IT WILL NOT CLEAR
