I just bought an OBD2 reader. Something that's been on my shopping list for some time, but never got or needed bad enough. Recent events on both my kids' cars proved that having one would have saved some money. I checked prices and ultimately bought one off Amazon for $15.99 because of the price and the great reviews. It does everything I needed it to do and works great. It can be bought here: http://www.amazon.com/OBD2-Reader-D...58AY/ref=sr_1_5?ie=UTF8&qid=1322669977&sr=8-5

Nice!! Although I spent quite a bit more, I bought the PLX Kiwi Blutooth OBII scanner and use my Droid to acces all kinds of info.

OBDII started getting phased in in 1997. By 2000, all carmakers were exclusively OBDII.

Do these distinguish "causation" though? I was doing some reading and they claim the less expensive ones will give you codes but not the full determination. The example I was given for instance. For example, you could see a code showing low catalytic converter efficiency, but the causation of this result can be from numerous other sources, not that the catalytic converter failed ...but such as a "lazy" or failed O2 sensor which is not triggering a DTC fault code of it's own. By having the O2 sensor live readouts, you can verify that these are functioning correctly ... and so it goes with other fault codes in the engine/emissions DTC's.

It just reads the code that is thrown. It's up to you to nail down the cause. That's why having the service manual to help with troubleshooting is a must. Speaking of which we have a free download link for the Caliber service manual in our "Manuals" section.

All OBD2 readers work with all cars from 1997 up. You can't buy readers for pre-OBD2 cars anymore, which were pre-1997.

Yes, that one will work.
