OK, figured out that the CP solenoid is the Canister Purge.
I have disconnected all of the following load devices:
ATX solenoid plug
EVR solenoid plug
MAF plug
IMRC plug
A/C WOT relay
PCM plug under P/S reservoir
EVAP canister plug
IAC plug
The short on pin 3 of the PCM relay remains.
Only load device I didn't disconnect was the VSS plug. I jacked up the 'Tour and found the VSS by hand, but how do you disconnect it? Does the whole sensor need removed? That ain't happening on the street!
Is it my luck the short is the last load device I can't get to (VSS) or is it in the harness... somewhere...
Since it happened while the car was cruising on the highway, any suggestions what might have gone poof at that time, as a starting point?
