Hi,
I don't have any personal experience, but I looked through the diagrams for you. The Engine Fuse is CB-3 and supplies 12 volts + in start or run to a number of engine items including: voltage regulator, MAF sensor, intake air vacuum switching valve, EVAP canister purge valve, EVAP canister cut valve, PCM relay, EGR solenoid valve, and maybe others. A pinched wire or corroded connector or other damage to any of these items would be suspect. Most would throw CEL but not all.
Hope this gives you a start. BTW I got the Electric Troubleshooting guide in the downloads section of this website and it is very helpful.
Good luck,
Dave
