Coolant Temp 

For most bikes this is a thermistor with a negative temperature coefficient. That is, as the temperature increases the 

resistance decreases. This is very similar to the Fuel sensor above – except that the maximum resistance becomes 

higher. 

Usually the resistance values are listed in the service manual for the bike and these form a good basis for the 

measurement values. 

A typical example from a honda sabre manual is 

Temp

85 Deg C 

110 Deg C
