my old o2 sensor had two black, one green, and one white wire. the new one has two black, one white, and one blue.

I know black goes to black (doesn't matter which), but I'm not sure about other wires. Can anyone help me out? thanks

I have a cel code either way, anyone know what the code could be from too?

 

anyone? the new one I got is a cheap bosch from autozone, don't know what the old one was

 

read the directions

 

White to white, blue to green makes sense to me....

 

here ya go. Omit step 1 and just follow step 2

 

white 2 white and green to blue would be your best bet . try to clear your ecu after u change it then if it still stays on go get it checked.
thats word
