Low oil pressure warning

[MTF]

Ok, it's highly unlikely but my thought is, maybe they tied in the oil level sensor of the LPG oiling system to the oil light? Maybe.

Aren't you running an oiling system for the LPG conversion?

lpg conversion also exists in the US?

The oiling system works through the lpg computer. When the oiling system is empty, only the light in the lpg switch starts flashing and after 60 minutes, the truck switches back on regular fuel and you can't run on lpg until you filled up the oiling system.

I just checked the connection for the sending unit. It looks clean and firm. If i disconnect the plug, oil pressure warning shows on the dash.
I will clean the connector with contact spray later at work.
I will clean the air filter and maf sensor too.

I just drove around and the low pressure warning popped up when i got back home. I had the obd link running and no error codes.
It's also not possible to read the oil pressure with the obdlink or dashcommand app.
I noticed i have no value for o2 sensor 1, only o2 sensor number 2. Is this normal?

The oil pressure switch does not give psi reading, it's only an on/off switch unfortunately.

Just FYI,

The O2 readings are only for the rear sensors, Bank 1 and Bank 2 and will need to get hot before sending any values.
If your not getting readings with the truck at normal operating temperature you could have what's called a lazy O2 sensor.
But this also normally will throw a code, so I believe you just didn't have the exhaust hot enough.

hello, it seems strange that the computer turns on information "oil pressure" and not laws ODBII no error code. In my case with the O2 sensor, even if new (raptor to 1000 km), gave yellow light alarm engine and I O2 "sensor 1 Bank 2" fault, then I replaced probe "lambda" from the driver's side. I use daschcommand and bought ford raptor 6.2 profile for a few dollars
