Default just EPC no CEL... AHHHH!!!!
So I had a bad MAF, fixed it. The Secondary Air Pump Rivets were coming undone, fixed it. Both CEL codes went away. Now just the EPC light remains. It was off for a total of five minutes one time just after I replaced the MAF. It has since returned and never vanished. DO EPC lights have codes or anything like that? Why would the EPC light be on for any reason? What is the EPC supposed to be? I thought it was traction control of some sort. Thank you, -JD

Default The MAF can make EPC come on.
Been a long time since I had MAF issues , but IIRC the EPC light comes on if you unplug the MAF .

Default You should probably re-set the fuel trims if you haven't done that..>
Pull the Neg. battery terminal for a few minutes.
