Hi, I am a first timer in this forum. Got a Y reg ford Galaxy 2.3 Petrol, in normal driving thermostat is holding the temp to 90 degrees, but when you get stuck in traffic for long time the radiator cooling fan does not kick in. The fan is working when connected to battery and so is control relay 419. Am I right in suspecting it is ECU or temp sensor feeding to ECU Error codes are P1474 Low fan control primary circuit malfunction P1479 High fan control primary circuit malfunction I will appreciate if someone can guide me in locating the temp sensor and ECU. Thanks
