The code P0481 on a 2007 Dodge Nitro refers to the “Fan 2 Control Circuit.” It is a diagnostic trouble code that indicates a problem with the cooling fan control circuit. The electric cooling fan in the vehicle is controlled by the Engine Control Module (ECM) through the cooling fan relay, which is responsible for supplying power to the cooling fans.
When the PCM detects a problem with the cooling fan control circuit, it triggers the P0481 code. This code is detected when the commanded state of the driver and the actual state of the control circuit do not match . The specific algorithms and circuit monitoring systems may vary depending on the vehicle’s make and model.
To diagnose the P0481 code, it typically requires 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops can vary depending on factors such as the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour .
If you are experiencing this code on your 2007 Dodge Nitro, it is recommended to consult a qualified mechanic or dealership for a proper diagnosis and repair. They will be able to accurately identify the cause of the issue and provide the necessary repairs or replacements.
Please note that the information provided is based on the search results and may not cover all possible causes or solutions for the P0481 code on a 2007 Dodge Nitro. It is always best to consult a professional for an accurate diagnosis and resolution of the issue.

What causes P0481 code?
The code P0481 may be triggered when the PCM detects that the command and the result do not match when it activates the number two cooling fan relay. The algorithms vary. Some systems will have a circuit monitoring the fan output to determine whether the relay is delivering power when switching is commanded.
How do I know if my radiator fan relay is bad?
The fans don’t start.
If the fan doesn’t work, it won’t cool the radiator. After a while, the coolant will start to heat up and won’t be able to take heat from the engine. In this case, it is most likely the problem will be in the relay as it supplies power to the fan, and without power, it won’t be able to work.
Why is my radiator fan not working on my Dodge Nitro?
The most common reasons a Dodge Nitro radiator fan isn’t working are the fan assembly, the fan clutch, or the coolant temperature sensor.
What is cooling fan 1 control circuit?
Diagnostic Trouble Code (DTC) P0480 stands for “Fan 1 Control Circuit.” The engine cooling fan system is controlled and monitored by your vehicle’s computer and various sensors. The PCM detects the temperature increase through the coolant temperature sensor.
What is the error code for cooling fan sensor?
The P0526 code stands for “Cooling Fan Speed Sensor Circuit,” which means the powertrain control module (PCM) has detected a fault within the cooling fan speed sensor or wiring.
How do I fix code P0481?
A P0481 is telling you that the 2nd circuit of your electric cooling fan in front of the radiator is having a problem – probably your fan isn’t able to kick into high speed. A new fan is a pretty simple, straightforward fix.
What is cooling fan 2 control circuit?
The fan 2 control circuit is an essential part of the vehicle’s cooling system. It’s responsible for regulating the secondary fan’s speed and operation based on the engine’s temperature. The fan helps the engine stay cool by blowing air through the radiator to dissipate heat.
Where is the cooling fan temperature sensor located?
The ECT sensor is typically near the thermostat in the cylinder head or thermostat housing. The ECT sensor is typically near the thermostat in the cylinder head or thermostat housing. Many vehicles also have a second ECT sensor on a different part of the engine or radiator.
What causes cooling fan relay failure?
Cooling fan relays can stop working for any number of reasons. Common causes for relays failing to operate might be: Failure of the computer, temperature switch, or relay control module that turns the relay on or off. Damage caused by changing between circuits with different speeds and electrical load.
Can a blown fuse cause radiator fan not to work?
The most common reasons for a radiator fan not working can be a blown-out fuse, a bad relay, or a broken wire. The faulty coolant temp sensor might also be a reason behind it.
