Hello teacher, for your questions; 1- DETAILED EXPLANATION OF P0693 ERROR CODE for fan - MEANING The fans used to cool the engine radiator work with electric motors. These engines are turned on and off by the powertrain control module (PCM) based on data from the engine coolant temperature sensor (ECT). In other words, when the ECT reaches a predetermined temperature, the PCM turns the fans on. The PCM then turns off the fans when the ECT cools to a predetermined temperature. The PCM controls the cooling fans by sending a ground signal to the cooling fan relay. As long as the operation is not ordered (not grounded) the voltage in the signal circuit is high, the battery voltage will be a close voltage. The opposite is also true, when the operation is ordered (grounded), the voltage is close to zero. DTC P0693 fault code, if the PCM detects that the voltage is low while the second cooling fan is off, this fault code occurs. Frankly, it's hard to comment without looking. The rear prevents it should be burnt independently. The answer to your question with orjinalinde3- turbo is in this subject, sir. https://forum.peugeotturkey.com/forum_posts.asp?TID=46232&title=208-ariza-lambasi
