Yes. Your Local Auto Parts Store should Carry these as Direct Replacements. If Not, Sears Carries them.

Wandering fuel guages are associated with a bad fuel pump/sending unit in the tank. Probably one of the reasons it was for sale. will be about $200 for unit and $100 to change. Check your warranty for coverage.
Good luck

2003 hyundai santa fe constantly jerks while idling.

it has to do with the injection system. Might be something stupid like a manifold intake gasket leak (commonly known as cylinder 4 misfire problem) or it could be a part of the system like : spark plugs, wiring, fuel injector, throttle position sensor. A low cost solution worth trying is a kleen flow injection system cleaner. It will remove a lot of carbon and see if it helps...

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
1. Oxygen Sensor
2. Oxygen Sensor

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

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.

Have problem with my hyundai santa fe exaust system 2004 2.4l.

If you are getting exhaust fumes in the engine compartment I advise checking the exhaust manifolds for cracks. When the engine is cold remove the heat shield from the manifold using a 12mm socket and inspect from the top and underneath for any cracking.
