Question about Cars & Trucks
Most of the time when I repair you have to run a few miles to get it to clear.. Also try tightning up your gas cap..

SOURCE: O2 Sensor Bank 1 Sensor 2
That is the O2 sensor right behind the cat. converter. When the cat is clogged it can shoot contaminates in the O2 sensor so sometime just cleaning the sensor will make it work again, if not it will need to be replaced. Mark - ABKS

Here are some possible causes, I would start with anything related to replacing the intake.
Air leaks in intake manifold, exhaust pipes or exhaust manifold
Fuel control sensor is out of calibration
Low fuel pressure (fuel filter clogged, pressure regulator failure)
One or more injectors restricted or pressure regulator has failed
O2 sensors contaminated, deteriorated or has failed
Vacuum hose is disconnected, broken, leaking or loose

is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.
if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.

check the mass air flow sensor there maybe dirt on the filiment inside the sensor causing false readings. cleaning or replacing it may make the codes go away.

There may be problem with the mass air flow sensor (very common with Volvo). This causes the fuel system to malfunction.
You may have noticed increased fuel consumption, loss of power and general 'lazyness'.
Better to take it to authorized Volvo service for a checkup/fix.
