EGR valve sensor and TPS sensor
I did a little bit of research on the site and couldn't quite find the solution to my problem. Im throwing two codes. 1. EGR valve sensor below minimum voltage. 2.TPS sensor below minimum voltage. I have been fussing around with my volt meter a little bit and i came up with some frustrating results. I am only getting a steady .35 volts at the EGR valve sensor, when it sould be 5, and nothing at the TPS sensor. I found the same color wires from the EGR sensor on the main harness connector and back probed them. I am only getting a steady .46 volts right at the harness. I checked all the fuses in the engine compartment for the hell of it and thay are all fine. Now i cant figure out where to go from here. Any ideas??

One of the sensors that use the 5 Volt supply may be bad or the wiring to the sensors.
The sensors:
1. TPS
2. EVP
3. MAP
Or the 5Volt supply is dead in the computer.
Also check that you have power to pins #1, 37 & 57 and a good ground at pins #40 & 60.
37 & 57 with the key on.
The 5 Volt supply in the computer is wired something like this (J1 is the big PCM computer plug):
