Why do I get error code p0481 on my fan?
There are multiple factors that can lead to this error code, some of the most common possible causes are: Open or shorted fan control relay harness. Open or shorted fan cooling fan harness. Defective faulty fan control relay 2. Faulty cooling fan 2. Poor electrical connections in the cooling fan circuit. Defective coolant temperature sensor.
How does the p0480 cooling fan relay work?
The PCM (powertrain control module) senses the increase in engine temperature through the CTS (coolant temperature sensor) located near the thermostat. When the temperature reaches about 223-degrees F (value depends on make/model/engine), the PCM will command the cooling fan relay to turn on the fan.
What causes the cooling fan 2 control circuit malfunction code?
The cooling fan should be commanded on under certain conditions where the engine requires more cooling, and this is controlled via the cooling fan relay. If this does not take place, the Check Engine light will illuminate on the dashboard. What causes the P0481 code? The cooling fan 2 control circuit malfunction code may have several causes:

What does the code p0481 stand for?
However, specific troubleshooting steps will vary depending on the vehicle. If your vehicle’s check engine light comes on and after pulling the code you find a P0481 displayed, if refers to the engine cooling fan circuit. It is a generic code applying to all OBD II (on board diagnostics) vehicles.
What are the possible causes of a p0481 code?
P0481 Possible Causes 1 Faulty fan control relay 2 Faulty cooling fan 2 3 Fan control relay harness is open or shorted 4 Fan control relay circuit poor electrical connection 5 Fan cooling fan harness is open or shorted 6 Fan cooling fan circuit poor electrical connection
What is the p0481 code for cooling fan 2?
P0481 code definition. The P0481 code identifies a problem with the control circuit for cooling fan 2. It is often associated with the P0480 code.
Is there an OBD-II scanner for p0481?
P0481 is diagnosed with an OBD-II scanner. A qualified technician will use a scanner that is capable of scanning the factory sensor readings (more advanced than one from the auto parts store) to read the code.
How much does it cost to repair a p0481 Dodge?
The cost of diagnosing the P0481 DODGE code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
