codes
I get these same codes on my 01 Six speed. The p0500 is the speed sensor and the p1693 is the companion code or whatever they call it, saying that it recognizes having a trouble code. Mine still runs fine. no check engine light. I don't have a chip or box on mine so I don't know if unhooking or re hooking the ez would make the code show up or not. I would say driving it would bring up the speed sensor.
