with those codes I'd say that this is an issue with the air pump or its attached hoses
This could be a bad pump, a bad hose connection is more common however.1st check the combination valves (combi-valves), at the rear of each cylinder head, for broken or loose vacuum hoses and repair as necessary.Verify that both combi-valves open fully when vacuum is applied to the diaphragms (use a hand-held vacuum pump or suck on the vacuum pipes) and check that the valves are not clogged up (remove the valves and visually inspect the condition and operation).Manually activate the Air Injection Reaction (AIR) pump motor V101 (this can be done with a scan tool in output diagnostic test mode or by jumping a power and ground source to the motor), and verify that the Air pump produces a large volume air.
Manually activate the Secondary Air Injection Solenoid Valve N112 with the engine at idle (jump power and ground to the solenoid) and verify that the manifold vacuum is available at the combi-valves vacuum lines.
The pump has a fuse and relay, so if the pump isn't running check these next
