saw in my local harbor freight flyer they have an OBD2 reader on sale for 39.99.

descent price... just a heads up....

 

that's a really good price, what brand is it?

 

Here you go.

It just reads general OBD-II codes, couldn't read my improper shift to 4th gear a while ago, or my friend's Prelude's knock sensor code, but it gets a fair amount for the price. I picked one of those up on eBay a few months ago for $30 shipped.

Here is a list of them on eBay between $20 and $30 before shipping, all pretty much the same thing.

 

what codes was it able to read accurately for you? Any sensor codes?

 

The only time I've tried to use it on my Maxima was for the tranny problem, but it correctly read an 02 sensor and some other issues on my Camry. Double-checked it with an Advance Auto Parts loaner, read just fine.
