Low oil pressure warning

Since the last couple weeks, my truck is randomly giving the low oil pressure warning on the screen and the gauge shows no more pression. It comes ang goes but the truck keeps running normal. The last days it is showing this message more and more. Sometimes once every 20 minutes and just goes away after 2 seconds, sometimes 10 times in five minutes.
I've searched the forum and the internet and found a couple who had the same problem but didn't find any solution.
Does anyone know where the pressure sensor is located?

It's a '13 with 80.000 km on it.
I also recently changed the oil and the oil was at the correct level begore and after i changed it.
Any suggestions? I can't bring it to a dealer because there is as good as no service for this truck in europe.

First thing I'd do is check for a loose connection to the sending unit; second the sending unit itself.
If all looks good I'd connect a pressure gage to see the actual oil pressure.

HI jef, whit interface ODBII you read what Ertor code did the raptor? I use torque interface with BT and ODBII.

I have no idea where the sending unit is located. Searched the internet but didn't find any information.

I have the bluetooth OBL link. I'll have to check tomorrow if and what error codes it's throwing.

Does the oil light come on at any rpm or is it when your coming to a stop and when idling?

Are you running any kind of Tune?

If your not using a Tune, then I would clean the MAF sensor with a MAF cleaner.
Check or get a better air filter.
And I know gas is expensive over there but running the highest Octane you can find will help your truck run better.

Note:
If the rpm drops below say 600 when in drive the oil light will light up.
Also if the oil pressure is in fact too low, the truck would go into "Limp Mode"

The light comes on at all rpm's, it's very radomly.
I'm not having a tune but it has an lpg conversion since it was new. I tested driving on regular fuel and does the same thing.
I have the k&n cai. I will check the filter and maf sensor. The filter is on there for 50.000 km. Only thing i noticed when installing, is the wiring of the maf sensor is a little short for the k&n.

It doesn't go into limp mode. It just keeps running normal.

I'll put these up for you.

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

Thanks for the information. I will check the connections tomorrow.
I'm running the oiling system for the lpg since the lpg was installed.
