What is going on with my engine!?!? Please Help

[offroadLAX]

Ok so my check engine light has been on for the past 3 months and I couldnt figure out what was wrong... I ran some tests and tested all my fuses... It turns out that my fuse located in the engine fuse box (#13 slot) has no power going to it... this is the... Heated oxygen sensor, EGR Vacuum Regulator, EVR Solenoid, Camshaft Postion (CMP) Sensor, Canister... As stated in the Explorer's owner guide... I took out the fuse and even tested the connectors and still nothing... what is my problem? and where is everything located on this long list of possible issues?

PLEASE HELP!!!!!
Thanks... 99 XLT

#13 always hot

. . . It turns out that my fuse located in the engine fuse box (#13 slot) has no power going to it. . .

According to the wiring diagram, Fuse #13 (30 amp) in the Power Distribution Box (PDB) under the hood is always hot. It gets power via the black wire that comes from the starter relay and goes to Fuse 1 (60 amp) in the PDB. The wire is the +12 volt common source for fuses 1,5,17,12,4,8, 6,15,21,14,22,16,19,9,10,7,11,18,3,20 and 2. Fuse 13 is the power source for the PCM relay. I suggest you recheck the voltage to Fuse 13.

I will be sure to do that... I went to advance auto yesterday and it turns out that my purge valve has gone bad... could this cause a disruption and not let power to the fuse or do i have two differant problems on my hands?

wait hold on acording to the book i have... slot 13 in the fuse panel under the hood is a 15 amp mini fuse which powers the "Heated Oxygen Sensor, EGR Vacuum Regulator, EVR Solenoid, Camshaft Position (CMP) Sensor, Canister Vent Solenoid"... the 30 amp fuse that you were talking about (PCM Power Relay) has power going to it and is fine... along with all the other ones and even to double check I tested everything out again...

just to be sure we are talking about the same slot this is the fuse that has no power going to it... Thanks again... hopefully we can figure this out soon enough haha

Fuse link vs fuse 13

Sorry, I was looking at a 1996 wiring diagram and fusible link 13 (30 amps) on the wiring diagram instead of fuse 13. Which engine do you have? I'll try and find the 1999 wiring diagram for your engine to determine what color wires go to fuse 13.

2000 wiring diagram

Last week I purchased a 2000 Ford Explorer wiring diagram book and it looks like it matches your description for fuse 13 (15 amp) in the Battery Junction Box under the hood.

The output of fuse 13 (light blue/orange) goes to canister vent solenoid, heated oxygen sensors 11,12,21,22, EGR vacuum regulator, and transmission torque converter clutch solenoid, electronic pressure control solenoid, and shift solenoids. If you don't have power to fuse 13 your transmission would not shift gears and the torque converter would not lock. You would be getting multiple transmission related DTCs. When you checked fuse 13 for power did you connect your meter between the fuse and ground?

The purge valve DTC read by Advance Auto sounds reasonable.
