Bad O2 Sensor. Sensor 1, Bank 1. Heater Circuit Malfunction. Where is this sensor located and how would I locate it? I assume from under the car, but I am not sure if I am looking for it on the front of the motor or the rear?

Is this a job that a normal do-it-yourself person should be able to handle? I would rather not have to disassemble alot of components to get to this sensor. Any suggestions or advise would be greatly appreciated. Thanks!

It's pretty difficult to tell you when you don't tell us which engine you have.

It's right in the exhaust manifold.

That looks it should be a huge help. Thank you very much. I will have to take a good look at it later when my wife is home from work. I will update as soon as possible! Thanks again.
