A L is used to indicate a low pressure system
Varies due to ambient temperature - need a chart for accurate readings
Could be a number of reasons. I'd recommend you take it in to a shop and have a system performance test done on it. While you could do it on your own with a manifold gauge set, you would have to be able to decipher what the pressure gauge readings indicate is wrong with the system.
HVAC gauges should read the system's refrigerant pressure and temperature. The exact readings will vary based on the specific circumstances and type of system being used. It is important to refer to the manufacturer's guidelines or consult a professional for accurate interpretation of the readings.

Is it that you are getting readings on your test kit that indicate that your levels are below the normal range? Is it a fact that you are getting low readings because you are not adding the product to the system -- via a floater or some sort of feeder. Do not add the tabs to your skimmer. What are your chemical readings. Without some detail we cannot help. k
The manifold absolute pressure (MAPO) sensor monitors the air pressure as an important input to the vehicle's EFI system. On this application the MAP is bolted to the intake manifold, from where it gets its pressure readings.
Blood vessels are the part of the circulatory system which transports blood throughout the body.Blood pressure (BP) is the pressure exerted by circulating blood on the walls of blood vessels. It means blood pressure is the speed of circulating blood on the walls of blood vessels.
2 reasons for the system to cut out, low pressure, and high pressure. I am thinking you are experiencing low pressure and need to recharge your system.
A simple system performance test will determine this. If you don't have a manifold gauge set, or don't know how to interpret the pressure readings to diagnose system faults, I'd recommend you have a shop do this.
I want to say it has something to do with the tire pressure monitoring system.
No, if you mean by "change", to change the pressure at which the dashboard indicator or message lights up to indicate low or high pressure. You can, however, turn the system off.
