From Lusty Kid:
I know the economy is bad, but change all of the plugs. Check your PCV Valve hose, 150 rottens them out allowing air to be sucked in, thus all kinds of codes.
Depending on mileage. Dismount the EGR valve and clean passages. If you are really good dismount the throtle position sensor body and clean out passages with Choke Cleaner., dismount where the EGR valves connects to the engine, clean out passages. Also check the hose thats behind this mounting to ensure is not clogged. If clogged clean it out. If not replace it. Is about 1.5 ft. long, connects to the PCV Valve Hose.
When is the last time you change your harness. Can't remember??? Replace it. Good Luck

you most likley have a blown fuse. the fuse for the connector and cig lighter are usually on the same circuit . if you have a owner manuel check and see which fuse is for the obd/cig lighter. if you dont have a manuel then check every fuse in the box and see if you find a blown one. the plug whare the scanner connects is what powers the scanner so if you cant find a blown fuse then you know youre not getting power to the plug for some reason.

Looked up your OBD II code for your Explorer and got the following: Bank 1 Sensor 1
The possible causes are listed below per Chilton: *same result for all engines available on your vehicle
Trouble Code: P0141 (4.0L V6 VIN E Auto)
HO2S-11 Heater Circuit (Bank 1, Sensor 1) Print this code data
Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
During testing the heated oxygen sensor (HO2S) heaters are checked for open and short circuits and excessive current draw. The test fails when the current draw exceeds a calibrated limit or an open or short circuit is detected.

When these codes are tried together it usually means O2 sensors are going bad. I suggest you get a real scanner on it before you spend $$$$$
