The P1211, is an ICP too high or too low for a given time, I want to say 4 seconds. Generally if you have a tuner that is commanding a higher pressure and it is not met that is the most common issue. The light will go out after a few minutes. If on a stock truck you might be losing high pressure oil, or could have a rare weak high pressure oil pump.

I wouldn't worry too much just yet.

Thank you. Oil pressure gage is perfect and towing perfect.

Yeah the dash gauge is for the Low Pressure oil side, it fills the reservoir for the High Pressure Oil Pump(HPOP)

Your injectors use High Pressure Oil to intensify and up the injection pressure to thousands of psi. The code point towards the Injector Control Pressure(ICP) not meeting what is being asked of it.
