MD is correct in a way. The gauge is controlled by a computer output.

"Analog instruments are controlled by the IKE from signals it receives over separate inputs. The needle of the coolant temperature gauge is centered if coolant temperature is between 75°C and 110°C."

75° C = 167° F
80° C = 176° F
85° C = 185° F
90° C = 194° F
95° C = 203° F
100°C = 212° F
105°C = 221° F
110°C = 230° F
115°C = 239° F
120°C = 248° F
