Is your truck running ok?
Is there a check engine light on?
Are you able to pass vehicle inspection?
If everything is ok, leave it alone as there's nothing wrong.
You have a special truck, converted to run on LPG. Some engine sensors and electronics are different then our standard gasoline engines we run here in the USA.
Perhaps the company that converted the truck can better answer your questions regarding the LPG ECU and its associated sensors.
I don't have check engine light in my speedo.
My vehicule work correctly, just the idle sometimes I have misfire. I wait my coil pack.
LPG system was installed in France in 1998, and this system don't need to connect on some sensor.
Just O2 sensor, for LPG Idle, and for my EX it's a new O2 Sensor was installed
LPG ECU was connected to:
Coil pack to know RPM
Injectors to disable they when LPG are ON
And TPS Sensor.
Nothing else.
So it's not LPG installator which modify my EX.

You don't have OBDII without O2 sensor.
You have the rest of the FORD points over their standard ECU network of sensors with an Data Link Connector as specified in OBDII - there was no need to create another one for export engines. They still needed those points to run the injected engine, it doesn't mean that it is OBDII compliant from emissions point of view.
Sorry, but my ECU is OBDII system, I have possibility to check ECU and all data with ELM327 and Forscan or ScanXL Pro or Scanmaster.
It's not a ALDL system, I know this protocol on my other 4x4, with a GM ECU.
My engine is OHV, so maybe this car was prepared for a race in US and after the race was cancelled. And this explorer was modify and sell like this.
I know it's possible to flash the ECU with a different program, and I know it's possible to cancel O2 sensor and some other sensor.
Please, let me know where is the ECU inside my car, I will check it and maybe read my EPROM inside.

sounds like this vehicle was imported w/out ODBII when new. maybe i'm wrong, but why would you need O2 sensors or a cat on an LPG converted vehicle?
About vehicule inspection, I have 1 defaut, it's the CO2 or Lambda.
I tried to do vehicule inspection, and my controller said that the CO2 is Correct in idle but Lambda not.
He tested with accelerator at half, and the CO2 was not good but lambda yes.
In france, all vehicule need to have Catalysor after 1996, and inspection need one to check CO2.
Mine don't have it, so the inspection was not good.
So, for futur I will have the same problem, because I don't have catalysor and O2 sensor, so my CO2 and Lambda Gaz will be not good.
If you want to see something on my Ex, please say me, I work on it today, I need to finish the body lift.
Bye
