544-08 Engine Cooling Fan Speed signal abnormal
544-02 Engine Cooling Fan Speed Sensor Loss of SignalThe engine cooling fan speed sensor provides a signal to the Electronic Control Module (ECM). The ECM controls fan speed by varying the current to the fan control solenoid.The engine cooling fan speed sensor receives a supply voltage of 8.0 0.5 VDC from the ECM. The sensor outputs a frequency that is directly proportional to fan speed. The sensor generates a signal pulse for each revolution of the fan. The output frequency varies between 5 Hz to 180 Hz over the speed range between 50 rpm and 1800 rpm.

Schematic for the fan speed sensor
Test Step 1. Inspect Electrical Connectors and Wiring
Remove the electrical power from the ECM.
