O2 Sensor Location

[mkasa]

I have a 2005 Hyundai Tucson GLS that is showing an error code of P0159 which states it is Bank 2 Sensor 2. Is this the sensor that is located downstream of the catalytic converter? I am confused because autozone's diagram does not show a Bank 2 Sensor 2 sensor, it has the downstream sensor labeled as Bank 1 Sensor 3. I have attached their diagram. Any help is greatly appreciated!

Thanks,
Matt

That is because autozone pic is not a Hyundai correct picture.

The exhaust manifold is the catalyst, so the sensor on the outlet side manifold there at front fron pipe flange is sensor 2.

Bank 2 is the left side (radiator side), sensor 2 is below the cat near the flane for the front pipe..

Before you drop the $$$ on the ox sensor, try the #153 Ox update program for the PCM, and see if any hidden data in the program takes care of the initial 0130/0150 and bottom sensor logic... at least you be up to date..

Thanks for the info!! This raises another question for me though......how do I update the program? Is that something that needs to be done at the dealer?

Thanks again,

Thats funny... a couple minutes after lunch here, I get Tiburon with MIL -- P-150 code,,,, same TSB for 5 & 6 Tib, Tucson and Santa Fe with 2.7, just different program number for each model.

Program is done by dealer using GDS in the ECU UPRADE mode.
