Help - Fault Codes P0160,P0174 and P2273

[Mike6]

I had the above codes appear after filling up with E10 fuel. I reset as I thought it was the fuel related but after about 60 miles the yellow engine light has reappeared with the same codes. I know these are 02 sensor related on Bank 2 Sensor 2 which is post cat . Unfortunately one of these codes is saying System too lean Bank 2 whilst another says Signal stuck rich Bank2 Sensor 2.
Obviously I need to replace the sensor but can anyone please point out where this sensor is in the exhaust system. I am not getting any younger and crawling under a jacked up car is getting less easy with each passing year. If it is not easy to access should I get it replaced at a garage. Thanks.

AS you say its the post cat sensor so access is from underneath on your back unless you can get it on a lift, going to need a sensor socket or a good fitting ring spanner on it to get the old one out and the new one in. Go for an oem brand, Bosch would be my choice, not got much faith in universal sensors that you have to wire. Where are you based may be someone close who has a lift thatr would help you out.
I'm in South Wales with a lift in my Zed Shed if thats anywhere near you.

Thank you. I am in the south East so South Wales is a bit of a treck for a sensor. Much appreciate the offer.
