p1627: [driver "1" input high voltage]...
I believe the PCM was expecting a signal from a sensor (which one I don't know) that should be low voltage and instead was high voltage and therefore triggered a DTC for that sensor...I will guess a bad O2 sensor...
code may also be cleared by disconnecting battery negative wire for 30 seconds...remember to reset your clock and radio settings...
sorry that is all I can find...please rate me solved

SOURCE: Where is the obd port
Here is a photo of the obd connector on a 1993 Isuzu Trooper.
The connector is on the transmission hump about 6 inches from the accelerator pedal. It is inside a black hood. Right next to the white OBD connector is an identical green connector that I have not tested.
The OBD port is a white 3 hole plug. Right next to it in the photo is a green 3 hole plug that I believe is for automatic transmission diagnostics. The plug is different from other plugs under the dash as it will not accept a .25" tab connector.
The picture shows a 20 ohm resistor being used to short pin 1 and 3 of the white plug. The resistor is to prevent a melted wire in case the plug shorted is the wrong plug.
To read the error codes from the engine computer, the mechanic is supposed to short pin 1 and pin 3 of the OBD port plug. Then the mechanic turns on the ignition switch and counts flashes of the "check engine" light to determine the error values being reported.

It is located just under the pan in a block called the valve body, it contains 2 shift solenoids, and a million little canals for oil. There is no drain plug on it, just have to drop the pan and spill out the fluid, that drips for months afterward. You can change these things if you are handy, if not, don't even attempt it. Watch out for the check balls,
