Easy as hell to make with a few wires and some LEDs. And only good if you think your car is throwing codes.

granted that item comes in a neat little package, but overall, complete ripoff. There's a guide somewhere on how to make one, but i can't remember where. Try searching.

 

If it had an OEM style connectors and displays the error code as a number, it might be worth it.

I made my own TPS adjuster with a 2-pack of 12V lamps from Radio Shack and crimp on spade connectors. Cost ~$5. I haven't tried it with the engine check connector yet.

 

I wouldn't buy it. I made the exact same thing (sans the fancy plastic housing) with parts from Radio Shack for less than $6, and it works like a charm (both for the TPS and checking codes).

I like this part (no offence to any member if this is your item):
