However surprised it hasn't recorded one or more of the following:-
P0130 O2 Sensor Circuit (Bank 1 Sensor 1)
P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P0137 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)
P0138 O2 Sensor Circuit High Voltage (Bank 1 Sensor 2)
P0139 O2 Sensor Circuit Slow Response (Bank 1 Sensor 2)
If you are going to fit one then you need to fit both.

I haven't noticed terrible economy. A trip to London with a speed of 70mph costs me £40. Local I get 80ish miles to £20. Although that's with normal driving, if I do hoon it around then it can drop to 70/60 miles. So around 15 litres of fuel from reserve light. I haven't got any other codes and did check any stored codes that may have been there previously.
I'm surprised you mention the codes that it hasn't thrown up. Anything else to look for? Can the ECU be written to erase certain codes to be thrown up?

Probably only way to know for sure is to get a mapper to check it out.
