A property ID is a 32-bit value packing four fields. Reading 0x1160030e apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x01000000	GLOBAL
Type	0x00ff0000	0x00600000	FLOAT
Ordinal	0x0000ffff	0x0000030e	0x30e

Reading it from an app

mgr.registerCallback(callback,
        VehiclePropertyIds.EV_BATTERY_AVERAGE_TEMPERATURE,
        CarPropertyManager.SENSOR_RATE_ONCHANGE);
