I need oxygen sensors locations and replacement

Cucuit voltage low bank 1 sensor 1, this is the 02 sensor on the exuast pipe or manifold, at the #1 cylinder side of the engine. If it is the problem, and not the wires, if you don't change it, initially you will burn more or less fuel than required by the engine! If too lean or rich you can damage the converter. Wayy more money than solving this problem, the 02 costs about 60.00 at a parts stor and up to 200.00 for a garage to do it for you.
