Anyone used an OBDII socket reader? I've been pretty pleased with the one I have from Davis, called the 'Drive Right' Car Chip Pro. It not only helps with diagnostics, such as Check Engine lights, but also recording vehicle performance and basic stats.

 

Off to troubleshoot a p0440: Evaporative Emission Control System Malfunction.

I use an Elm based cable with several different free softwares. They are handy all right to read live data.

 

There are several articles about p0440 here... http://endwrench.com/main.php?smPID=PHP::search_articles_action.php&
