Found it when I took the air box off and its not plugged into anything. Two winters ago I had the clutch changed by a shop and found out they had not reattached wiring brackets and other little things here and there and not sure if they left this plug unattached or if it is just a empty plug. Please help thanks.

 

Just did this a few months ago. In that area, you have the throttle body, one of the intake pressure sensors, the head coolant temperature sensor, but I think those would all give error codes if left disconnected (or run like c!%p).

Under the intake on the transmission housing is the reverse switch - check to see if your reverse lights (on the back of the car) are working - if not, thats probably it. And of course, that switch wouldn't give an error.

 

Looks like your reverse light switch on the trans, check your reverse lights they aren't working.

 

thats why they weren't working.... I was going to try to change the sensor later because I was told when I was backing into a space at school they were not on.... Solve my issue thanks.
