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 do I check oxygen sensor on a Hyundai santa fe 2004


If the check engine light is not showing trouble codes for O2 sensor, it's still working. Although they CAN still show okay while operating with degraded performance. They are supposed to be replaced every few years, but no one does. If you want to test it, you have to remove it from the car, hook up a VOM and heat the sensor while watching the volts. Not really worth the trouble. Just replace it!

Where are the o2 sensors on a 2004 santa fe


the sensors are in the exhaust system. if you have a v6 there will be one in each exhaust pipe coming off the engine one before the catalytic convertor and one after the catalytic for each pipe. it takes a 7/8" wrench or an o2 sensor socket to replace the sensors.

If your vehicle has a V-6 then it would be the first o2 sensor on the exhaust coming of the front of the engine.If it is a 4-cylinder. then it will be the first o2 sensor coming of of the engine.

2001 Hyundai Santa Fe - Code P0421 Help!?


code p 0421 refers to warm up cat converter bank 1 --- efficiency below threshold ===causes ---cat converter---wiring ---HO2S (heated oxygen sensor )
there are not 4 oxygen sensor as you have been told but just 2 oxygen sensors located after each of the cat converters
The other 2 are heated oxygen sensor which are located in the exhaust manifold or exhaust pipe before the cat converters
heated oxygen sensors do a completely different job to the O2 sensors in that they report to the ECM, the combustion gas mixture so the the ECM can adjust the mixture for max performance
The oxygen sensors (O2) read what is left after the cat converters have done their job and report to the ECM so that it can fine tune the mix
IF you didn't replace the correct cat converter then that will make the code come back
If you just replaced the O2 sensor , well that doesn't even figure in the problem
