If you want to find out what's causing the code without making the two-hour drive, you could stop by an Autozone and have them plug in their OBDII scan tool. They'll probably get a kick out of seeing your Maser.
I wound up getting one of the relatively inexpensive readers from Actron. It reads the code, plus allows you to reset the code to see if your problem comes back.
The Actron units appear on eBay regularly. Here's one: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=2489775487&category=43989
The typical scanner probably won't help detect CambioCorsa problems, though. There must be some room in the OBDII standards for extensions by the manufacturers...
