Hi guys,
Need a little help troubleshooting DM code 5 issue. In the 14 years I've had this car, this code has come back a few times over the years...so far with different issues each time.

The check engine light has been coming on for a couple weeks now, generally it only takes 3 to 4 restarts after clearing to come back.

Secondary air tube is clear and EGR valve works...tested at idle with vacuum source to EGR valve, this caused RPM drop and slight miss.

The air pump itself also works when 12V is applied directly.

I think the issue is that the computer is not able to engage the air pump. I used to hear it run occasionally, now I don't.

Is there a fuse or relay for the pump? If so, where is it?

Thanks,
Glen
