The only mention of this system in the Haynes manual reads as follows :-
"On this system, air is injected into the exhaust manifold before the lamda sensor and catalytic converter have reached working temperature, in order to assist the combustion of hydrocarbons. The saystem is activated when the engine is started, and its running time depends on the engine temperature and the point when the lamda sensor begins to operate."
Haynes also recommends that the lamda sensor be replaced every 60k miles. The manual also advises that the part is extremely delicate and that it will not work if it is dropped or knocked, if its power supply is disrupted or if any cleaning materials are used on it.
Maybe its the lamda sensor you should check first.
That's all that I can give you on the subject, hope it's of some use
