Help Toyota/Lexus tech or anyone that knows......

Ugh.... you shouldnt "just" splice the wires. If the connection isnt right the part isnt right...you might be putting an oxy sensor in when it needs the air/fuel or vise versa. Know what I mean? Just get a factory part. where do you live?

Exactly.

That is what I was trying to tell him in the beginning. One is a regular ole O2 sensor and the other is an Air/Fuel sensor. They look alike, but they are different. If he replaced it with a run of the mill O2, he will still have the code. If he didn't reset the ECU, he may still have a CEL.

dfire9: Get the part number off the old one and post it up here. Derek can look it up and tell you which one it is and just replace that one and reset the ECU. Done.

More than likely you just replaced the wrong one or WITH the wrong one.

thats what im saying. And dfire, im not trying to be a dick here...me and jamie are saying is that car can have either one,does that make sense? Bank 1 sensor 1 can be either one.
