Arrow Radiator fan failure n52b25

Hello everyone, I hope you can help me with this problem, which is breaking my head

the error is not present all the time and the truth is that I would not know how to say that so many times this happened at the time I checked with INPA for the first time I only marked it once and now 3-4 days later it appeared again and disappeared after a while, The fan also does not turn on when I turn on the air conditioner when the error is present

Just as an extra fact the fan had been turning on as soon as I turned on the car, which I feel is not something normal


I am having an intermittent error with the radiator fan marked by INPA as 2EFE, I did some research and saw that the error may be caused by:

-damaged fan (I rule it out because when the error does not occur I can control the fan speed with INPA without any problem)

-Failure in the relay (I don't know exactly if my car has one since I saw that this is on the passenger side behind the fender I looked for it, but I didn't find it)

-any fuses damaged (I checked the fuses that have to do with the fan and cooling system, and none are damaged)

-Damaged cables (check the voltage of the connector to the fan and it has 12V and the one of the PWM signal reads 4.7V, all this, even if the fault occurs and the fan is not turning on the voltage does not change)

I need to check the temperature sensor that I have seen in some video that could cause the fan not to turn on

I don't know what other component you could recommend me to check, or if you could tell me if my car has a relay for the radiator fan and its location, I would appreciate it

sorry if you don't understand some parts of my explanation, but I'm using the translator
