You have an heated Oxygen sensor. 2 of the wires heat up the sensor and keep it at a certain temperature, it is turned on and off by the computer. The other 2 are use to send a very low voltage reading back to the computer to tell the computer if the engine is running rich or lean. I don't have a diagram to tell you which wire does what but you can get a manual and that should give you the information that you need and tell you how to trouble shoot it to tell if the sensor is bad or not, you may want to look for a wire laying on the exhaust, I have found wires burnt and lay on the metal.

Where is location of bank 1/sensor 1 oxygen sensor v6 ?


Bank 1 means the side of engine which has #1 cylinder in it, which is the left or driver's side of the engine. Sensor 1 means it is the one closest to the exhaust manifold or before the catalytic converter, better known as "upstream" oxygen sensor. On the 4.3 V6 I believe this sensor is mounted in the exhaust manifold itself. You maybe able to access it from underneath the vehicle, or you may have to remove the "doghouse" interior engine access hood. The oxygen sensor has an electrical connector on it that has to be disconnected and the you may need a specialty socket called an oxygen sensor socket. the size of the hex on the oxygen sensor is 7/8".

I am trying to locate the Oxygen Sensor on my 2003 Impala?


Chevrolet Impala comes equipped with two oxygen sensors, one on either side of the catalytic converter. Locating the sensors is as simple as crawling under the vehicle.

  1. Location
    • The bank 1, sensor 2 oxygen sensor is located downstream of the catalytic converter. To get to the sensor, crawl underneath the vehicle and trace the exhaust pipe until you reach the catalytic converter. Continue to follow the exhaust pipe until you reach the bank 1, sensor 2 oxygen sensor.

    Identification
    • You should be able to identify the oxygen sensor as a single wire about 3 to 6 inches long. The oxygen sensor is mounted to the exhaust pipe and should slightly protrude from the pipe.

    Function
    • The oxygen sensor is an important part of the vehicle exhaust system. The sensor tests the amount of air in the exhaust stream. It then sends this information to the engine control computer, which determines how much fuel is necessary to maintain a proper air-to-fuel ratio.

Where is the O2 sensor located on the 2003 V6 All Wheel Santa Fe and how dificult is it to replace?


Hyundai Santa Fe 2001-05
Heated Oxygen Sensor (H02S): The sensors are located in the exhaust system. On some vehicles, one sensor is located up at the exhaust manifold(s) and the other sensor is located down at the catalytic converter. On other vehicles, both sensors are located down at the catalytic converter.

How to Replace an Oxygen Sensor
Parts:
1. Oxygen Sensor
2. Oxygen Sensor

Tools:
1. 3/8 in. Drive Ratchet
2. Multimeter
3. Oxygen Sensor Socket
4. Combination Wrench Set
5. Crimp Tool
6. Socket Set
7. Scan Tool

Steps:
Step 1 * Park the vehicle on a level surface. Set the parking brake and open the hood.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Always make sure the struts on the hood can fully support the weight of the hood so that it does not close on you while working. The use of a hood prop can securely hold it in place.

Step 2 * With the engine off and cool, locate the defective oxygen sensor in the exhaust manifold or pipe. If necessary, lift the front of the vehicle and support it with jack stands.
o Tip: Most vehicles have multiple oxygen sensors. How many sensors, depends on the model year and type of engine.

Step 3 * Disconnect the wire connector at the defective oxygen sensor.

Step 4 * Remove the oxygen sensor from the exhaust system.

Step 5 * If you are installing a universal oxygen sensor, cut off the connector from the original sensor and splice the connector wires to the new oxygen sensor. Follow the manufacturer’s instructions supplied with the sensor.

Step 6 * For threaded oxygen sensors, apply anti-seize compound to the threads and install the new sensor.

Step 7 * For flange mounted oxygen sensors, install a new gasket and tighten the mounting bolts.

Step 8 * Reattach the wire connector from the sensor.

Step 9 * If necessary, connect the OBD I/II scanner and erase the fault code.

Hope help with this (remember rated and commented this help) Good luck.
