i keep getting code 17 for o2 sensor, i replaced the sensor, code still pops up. i checked my wiring diagam for the computer-- should be location 2d, but there is no wire at that terminal, if anyone can help it would be greatly appreciated

 

maybe someone ripped out that pin/wire. One thing that comes to mind is that I remember S5 ECU's having a memory for codes which means they store them untill you clear out the memory. Maybe you just need to clear it. But try looking for that wire around there or just trace it from the sensor.
