Having intermittent electrical issues and have narrowed it down to the terminal wire connection at the ECM for the common ground to the TPS, VPS, MAF, etc. Truck starts but if terminal wire is moved then error codes appear or it stalls. Some error codes are triggered at initial start, but sensor tests fine at investigation. Common ground is the E2 at the ECM and the terminal housing is the E6 connector. Have replaced terminal wire and housing with certified parts from a dealership. Have tested for continuity at sensors and tested ECM and both test fine. Any thoughts or information is much appreciated.
