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... :) Greg

I don't think it's available to consumers. You could always stop by the dealer and ask. I've found scan tools at www.northerntool.com in the automotive tool section http://www.northerntool.com/webapp/wcs/sto...81374_200181374 Don't know if it will give you the info that the Mitsubishi Scan Tool will give you.

You most likely will have to replace it.
