So last week I got a CEL. When I scanned it with the taser, it pulled two codes. P023B and U20A9 both related to the aux pump. I checked the fuse for the pump and it looked discolored like it got hot. I also checked power and ground at the harness and they are good. The pump sometimes will kick on, but it doesn’t sound great. I checked the price for a new pump and I was shock to see how much it cost, between 300 to 450. I decided to grabbed a used one from a newer and low mileage and paid a fraction of the cost. Hopefully that will solve the problem. And yes I’m out of warranty at 75k miles.
