Cooling Fan Circuit Diagnose at Marjorie Hubbard blog

Cooling Fan Circuit Diagnose. Coolant fan control module (j293). The cause could be a faulty relay, a damaged wiring harness, or poor electrical connections. Test the fan relay and replace if necessary. Usually a faulty cooling fan relay will produce a few symptoms that can alert the driver that service may be required. Symptoms can include an overheating engine or the cooling fan not working at all. To fix the issue, visually inspect the wiring and connectors for any damage or corrosion. Measure resistance of the cooling fan motor to check for shorts or open circuits. Damaged or shorted wires in the cooling fan circuit can trick the system into thinking it needs to turn the fan on. Dtc p0480 registers when the pcm doesn’t receive the proper amount of voltage from the cooling fan control circuit that should indicate that the fan works properly. This code can be caused by a faulty cooling fan relay, a bad cooling fan, damaged wiring, or a bad coolant temperature sensor. When a certain engine temperature is reached, a call signal (power/ground) is provided to the #1 cooling fan circuit. To diagnose the issue, a mechanic will typically use a scan tool to read the code and then perform a visual inspection of the fan and. Diagnostic fault code p0480 is logged when electrical feedback pertaining to the circuit’s voltage/amperage is deemed irrational or illogical by the controlling pcm/ecm.
