are they scan tools?

Sort of...these are only for ODB I cars. You just plug it into the ECM access port under the dash and it will let you know what codes may be stored. This is a somewhat more convenient way of doing it compared to jumpering two of the pins in the port and counting the flashes of the check-engine light.

When they first came out, they were like $30-40. For the going price on that auction, it might not be a bad deal.

Will it work on my 92 SE and what is an ODB I car?

OBD or On-board Diagniostics is the protocol that most automakers have standardized on for pulling information from the ECM. OBD I was the first version available. It offerered basic retrieval of codes and diagnostics for those (mostly dealerships) with the right tools. OBD II (available since 1996) has a ton of info available, some in "real-time". For example, you could drive around with an OBD II scanner connected and it could read almost every value of every sensor on your car.

Thanks for the info.

Those won't do anything more than a paperclip would.

Bridget, Fuddy is right. That does the same thing a paperclip does. There'* an article in Techinfo that will tell you how to extract codes on cars up to and including 1993......which car were you thinking of using this on? It'* only good to 93 also.

My 94 is OBD 1 but with OBD 2 plug. Are all 94'* like this?

So you have to have OBD I connector to do the jumper thing. It would work on your '92, but not your '94.

For the 94 and 95 you must have an OBD-1 tool that fits a 16-pin connection.
