Coolant Temperature
A NTC sensor is used to measure coolant temperature the cluster uses this input for temperature gauge display. The NTC sensor is a dual NTC, one of the NTC circuits is an input to DME, the other NTC is an input to the cluster.
From 9/98, the coolant temperature sensor in an input to the DME only, the cluster receives the temperature information via the CAN-Bus. The dual NTC is eliminated.
