Im just about finished with my project car and I pulled the codes for the car and these are the codes I got

51
22
53
54
35
67
81
82
85
84
95

 

I have checked all the sensors signal return wires and with the car in the run position and running the voltage reads 4.95 volts at every sensor and even the signal return wire at the EEC Test Plug.

How is this happening

 

This will give you what the codes mean if you dont already know.
