Default OBD II error codes p1132 and p0140

I got an auto scanner that reads and erases codes because I have a check engine light on. The first code I got was P1132 Manufactuer Contrl. Fuel Air Metering
second code is P0140 (Bank 1 Sensor 2) 02 sensor CKT no activity.

any idea what either of these mean?

I am thinkin one is an o2 sensor as I took this 99 vovlvo with 195k miles on it to a vovlo repair shop and he said that I need to replace both catalytic converters and all four O2 sensors wich is going to cost more than 4k in parts alone according to him.

Thanks in advance for you help.

BTW the car runs great except for the check engine light and the srs airbag message.

The 1132 I believe is a bad mass flow sensor or a vaccum leak which would also cause the O2 light to come on. But you might still have a bad O2 though.
