Default Which O2 Sensor does code P0154 refer to?

I changed my O2 sensors and I keep getting the same code after clearing it a couple times. I get the code P0154 which I think is bank 2 sensor 1. Can someone confirm? Is this the front drivers side?

I'm going to get a replacement from Atlantic British and just want to make sure I get the correct one.

No, it is the passengers front 02.
With your mileage you should be replacing them all.

Keep in mind that 90% of all Rover O2 codes are due to the need of a tune up.

I did change all 4 O2 sensors, this is the one code I am getting now after changing them, there were no codes before I changed them, I did it as maintenance. I changed the ignition wires to magnecores and the plugs are new.

Should I try a new sensor from Atlantic British?

Does this code mean though that is not even recognizing the O2 sensor (P0154)? It's not the other high temp code, just wondering if it point to a faulty O2 sensor or do I need to take it in to a Land Rover dealer or should I get a new sensor for Atlantic British and try to reinstall it?

Really? That's great to know... I'm getting the other 3 sensors come up. Wouldn't be a bad idea to do a tune up before dumping a bunch of money into new sensors... its about time anyway. Although with 3 coming up there's probably a good chance they will need replacing.

Thanks for the heads up,
Brendan

With that code, no sensor detected, check your connections and then if all is good then you may have gotten a bad O2.
Call the place you got them from and do a exchange.

Connections are good I just wanted to make sure P0154 was actually the front passenger side which I'm glad its not the front driver sides because that one was a b!@ch to reach.

I think that bank 2 is passenger side and sensor one is the front one.

154, the ECU sees it but there is no activity from it, as in dead. I would suggest you check and clean the connection, if it is still there then contact whoever you bought them from and get it warrantied.
