I tested it on my XPS13 9333, here what sensors outputs:

acpitz-virtual-0
Adapter: Virtual device
temp1:        +27.8°C  (crit = +105.0°C)
temp2:        +29.8°C  (crit = +105.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +62.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:         +62.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:         +61.0°C  (high = +100.0°C, crit = +100.0°C)

i8k-virtual-0
Adapter: Virtual device
fan2:           0 RPM
CPU:          +62.0°C  
Ambient:      +49.0°C  
SODIMM:       +46.0°C  
temp4:            N/A

CPU seems to be correct, but I can't say anything on Ambient and SODIMM.
temp4 is constantly equal to SODIMM without this patch, so I'd say N/A
is correct.
