Hyundai Entourage GLS: I have a 2007 Hyundai Entourage GLS The

This answer was rated:

I have a 2007 Hyundai Entourage GLS

The check engine light comes on and off. Today, when it was on I stopped by the auto part store to use their code reader. I got two codes:

P0160 mod $11
oxygen sensor
circuit no activity
detected bank 2
sensor 2

P2273 mod $11
oxygen sensor
signal stuck rich
bank 2 sensor 2

Code Summary
Global 2 codes

So my question is which O2 sensor(s) is/are bad, and where are they going to be located so I can switch out the correct O2 sensors. They looked to be abobut $100 each at Advance Auto Parts, so I don't want to replace all if I don't need to.


Hello I will help you with your question,


All the codes point to the same sensor and that is in the front exhaust pipe farthest from the engine. This is behind (toward the rear of the vehicle from the engine in the exhaust) the cat. The code is for a sensor shorted to power so take a look at the wiring as well as the sensor.


The DTC troubleshooting is below and has a diagram of the sensor location

thanks, XXXXX XXXXX good info

i am trying to make sure i order the correct part, would this be the downstream rear oxygen sensor?

I don't trust that the customer service reps from advance auto parts always know what they are talking about. They have told me a part was the correct fit before and when i got it home I would find it was not the correct part.

This is the part i was looking at ordering:

Yes that sensor is supposed to fit your vehicle. I see they are asking $108 for that sensor, I always want to use the factory parts if possible and the list price for the sensor from Hyundai is $122 part number 392103C400 so you might want to go that route and eliminate any chance of getting the wrong sensor.

i appreciate all the help.

will it hurt to drive the vehicle before I get the O2 sensor replaced? I don't want to cause other problems, but hate to pay extra for overnight shipping to get the part sent in to the dealer here.

No problem running it with the Light on, it does nothing but monitor the working of the converter so as long as you don't mind looking at the light you can run it.


I am amazed the dealer doe not have this sensor in stock, it is an "A" part and they are supposed to have it ready.


Please let me know what I can do to help you and if you have further questions


Thank you

Thanks, I finally got ahold of the Kia dealer and was able to get the part from there. The local parts stores did not have the aftermarket version in stock, it and all were at least 2-3 days to get it unless I paid the extra for overnight delivery. I didn't know how the dealer stock would be, I could never get through to the parts counter at the Hyundai dealer and the never called me back, but luckily the Kia dealer was able to get me the part. I will get to work on switching it out here in just a little while. I will let you know if I encounter any other problems and need further assistance.

Thanks again for your help.

Great, the KIA and Hyundai parts are identical, the aftermarket may not be.


Let me know what I can do to help you with this and I hope it is the relay.

What size socket does this sensor require? Ddo I need to get a deep socket?

The socket is an O2 sensor socket which has a cut in the side for the wire. It is a 7/8" and is available at any parts store.
