For about a year now, I've had my CEL on with the code P1413, which is secondary air pump low voltage. Since it is simply a very small emissions problem I haven't really put it at the top of my list, but today I've finally gotten around to measuring the voltage. I took a voltage reading from the harness (or what I believe is the harness to the SAP) and I got a reading of about 7.5 volts. I'm assuming it should be higher than that. Does this mean that the relay is bad?
