[001240]

I have an engine light on and has been read as P0135 which I understand to be the 02 sensor in the exhaust. However i am unsure about which 02 sensor it is as there is 2. The code says bank 1 sensor 1 so could anyone indicate which one this is as the price difference is quite substantial. Thanks

It will probably be best to replace both. Sorry
