What engine do you ahve in your Sebring?
This code is stored when the computer commands the air injection system to operate, but the MAF sensor sees no change in the volums of air entering the engine. Since the air for the air injection system passes through the air filter and MAF sensor, a normal response would be an increase in engine airflow when the injection is activated.
This is a 2 trip fault; it has to occur twice on subsequent trips to store the code and turn the light on.
Possible causes include any kind of air leak in the air injection system, an internal MAF sensor problem, or an internal PCM problem.
Apologies; apparently this is an unusual setup compared to the ones we have seen in our shop.
on yours, the MAF sensor is used only for air injection monitoring; it is attached to the air injection inlet hose, directly below the filter.
