Re: CEL's constanly showing up (JasonP)
The secondary air pump solenoid you are talking about has a small vacuum hose going to it,check that hose for leaks,snip 1/2 inch off end of hose and replug,it mght re-seal itself.You will get the code for 2ndary air flow if that solenoid does not open for whatever reason.It could be a bad "vacuum switching valve",follow the line from solenoid.The next things are the pump itself (in front of motor)the air hose coming off pump,or the pump relay.You can unplug the pump and jumper the connections and see if it makes noise (runs)Visually check the accordian air hose for cracks.The relay and vacuum switch have to be tested with troubleshooting tools you may or may not have.Good luck!!
