Is your car overheating?

 

Yes. My car is overheating. The fans not turning on. Im already install the coolant sensor and the car worked well for two days. But now the car have the problem again and the three codes.
Thank you very much for try to help me ¡!¡!

 

Check the fan fuse and relay.

 

I'm checked the fan fuse and relay and its ok. But the fans dont turn on. I dont know what is the problem. I do everything and the fans dont turn on. . Please help¡¡¡¡¡¡¡

 

How did you verify the relay is good?

 

Im verified with a voltimeter with the car on and off. The voltimeter show the correct voltage. Now I ask you which relay I need to verify? Because I verified the fan relay in the PCM. Thanks for all buddy. Im very

 

Have you tried running a wire from the battery to the fans to verify the fan motor works?

After that...test the wiring between the PCM and the radiator fans by disconnecting the PCM connector C2. Momentarily ground pin 18 of the connector, not the PCM. Radiators should turn on right away. You don't need the ignition on at all as this circuit is always hot.
