I'm having some issues locating the source of error code P0403 (EGR solenoid) on my 2000 Mits Eclipse Spyder. There seems to be power to the solenoid (about 5v), which appears to work. Can I also check for loose hoses, etc? I've been lazy about fixing this since the warning light came on, but the car just failed emissions because the warning light is on.
I've replaced the PCV valve, and the suction on the PCV hose seems strong.
Thanks for any help, I'm pulling my hair out... :)
Every EGR solenoid problem I've seen is that it gets stuck open or closed. You most likely will have to replace it.
