Stuck digital speedometer, o2 sensor questions

I feel like my 05 3.0i manual is burning more fuel and the maximum mpg i have gotten is 22mpg. It has 110k miles on it. Carly captured some errors which i have pictured. Also, the digital speedometer is not reading right speed. I have swapped the abs module and have not coded the vin. Any ideas expert fellow z owners?
