P0481 on Jeep
Cooling Fan 2 Control Circuit
P0481 on Jeep vehicles indicates cooling fan 2 control circuit. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. This code indicates the PCM detected a fault in the control circuit for cooling fan 2 (a second engine cooling/condenser fan relay or circuit). The cooling fans help regulate engine and A/C condenser temperature, especially at low speeds and idle. A fault can lead to reduced cooling performance, potential overheating in heavy load or hot conditions, and poor A/C cooling. It should be checked promptly to avoid overheating risk. Typical repair costs on Jeep range from $450 to $1,600, depending on the specific model and root cause.
Common Causes of P0481
- •Faulty cooling fan relay (fan 2)
- •Open or shorted wiring in the fan control circuit
- •Corroded or loose connector at relay or fan
- •Failed cooling fan motor
- •Blown fuse feeding the fan circuit
- •Failing PCM (less common)
P0481 on Jeep by Model
Jeep Grand Wagoneer(1 issue)
- Cooling Fan Module Failure / Overheating Warning2021-2023
The electric cooling fan module on the Grand Wagoneer has been documented to fail, causing the dual electric radiator fans to run at reduced speed or stop entirely, resulting in engine coolant temperature spikes especially at low speeds and in traffic. The fan control module can develop internal MOSFET failures due to heat cycling, and Stellantis issued related service guidance through their dealer network. Owners report the temperature gauge rising into the red zone during stop-and-go driving and the A/C compressor cutting out as a secondary symptom.
