it some cases, when the soloniod shorts out for the air pump, that short takes out the pcm. you need to take it to someone who specializes in drivability issues to confirm. Roy

Was your problem ever fixed? I am having a similar problem with my Ford Focus 2006. They are stating the panel for the air injection is sending a trouble signal. I am at the start of my journey to try to figure what exactly is wrong. The mechanics just reset the sensor today. If the light comes back on, I have to have more detailed work done.
