Jeep P0481 Code is an error code associated with the cooling fan system of a Jeep. This code is triggered when the two speed cooling fan does not work properly due to a malfunction in the Low Speed Fan Relay and Hi Speed Fan Relay, and causes the engine to overheat. This code can be caused by a RADIATOR FAN RELAY CONTROL CIRCUIT OPEN/HIGH RESISTANCE, a faulty RADIATOR FAN RELAY, or a defective POWERTRAIN CONTROL MODULE (PCM). To prevent this code from occurring, it is important to identify and address the cause of the error.
