P0480 CHRYSLER - Cooling Fan 1 Control Circuit...Possible causes; Faulty fan control relay, Fan control relay harness is open or shorted, Fan control relay circuit poor electrical connection, Faulty cooling fan 1, Fan cooling fan harness is open or shorted, Fan cooling fan circuit poor electrical connection...Description; The electric cooling fan is controlled by the Engine Control Module (ECM) through the cooling fan relay based on inputs from the following components: - The engine coolant temperature (ECT) sensor - The intake air temperature (IAT) sensor - The A/C selector switch - The A/C refrigerant pressure sensor - The vehicle speed sensor (VSS) The ECM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay. The cooling fan relay will be commanded ON when the following conditions are met: - The engine coolant temperature reaches 106°C (223°F) or more. - The A/C clutch requested. - The vehicle speed is less than 38 MPH. The cooling fan relay will be commanded ON regardless of vehicle speed when the following conditions are met: - The engine coolant temperature is 151°C (304°F) or more. - The A/C refrigerant pressure is high. The cooling fan may be commanded ON when the engine is not running under a fan run-on conditions described in the electric cooling fan general description portion of the service manual.

On the car, both the low speed and high speed fan come on while about 1/3 rd of the way on the temp guage . This still trips the 480 check Engine light and some times the Battery light. The car runs mostly normal once it is warmed up It is next to impossible to get it to run long enough to warm the motor.

Same error here, except PT has been parked for winter, after 7 months battery put back in and immediately P0480. No way is it hot or even warm yet.
