Good morning welcome to just answer I am master tech and will be able to assist you today.
bank one is at the firewall,sensor 2 is the second
the p2240 will be set is teh air flow sensor is dirty ( dirty air filter) or the wire in the sensor has dirt or oil residue from the oil filter like a K&N
but to answer your question yes these codes are all related.
please see the attached info
yes thats the 02 sensor heater most likely a bad heater in the 02
sorry I misread your sensor info. the sensor 2 is the top sensor not the second one.
so you have 2 sensor codes. follow the service info provided and then recheck.
im sorry for some reason I got the info all confused.
ok your air filter can contribute to these codes but to proceed we need to address the issue at hand first.
replace the air filter and then clear the dtc's and road test.
most likely you have a failing 02 sensor but after clearing the codes you should get one primary code.
