lambda

I have an engine fault code P2238 on my 2017 150bhp T6. Carista is pointing me towards O2 sensor "low bank 1, sensor 1". Can anyone tell me where to find this sensor pls? A part number would also be really useful. Thanks

Hi Iv had a fault with lambda sensor 1 Iv replaced it same fault showing So suck another on still same fault it’s saying short to ground on diagnostics any one help much appreciated
