You can find O2 sensor wiring diagram for a 2003 Tiburon GT in the owner's manual. You can also find it at auto parts stores.
The O2 sensor on a 2003 Cadillac Northstar engine is located in the exhaust manifold. The readings from this sensor are sent to the vehicle's computer, which makes constant adjustments to the fuel and air mixture.
Stop by your local AutoZone. They will hook it up to a handheld tester and print out which oxygen sensor is failing.
