Contur 96 temperature sensor problem

Hello friends again here this time with a problem that I have not been able to solve I have at least 2 days breaking my head
I can help me with this

I have a contur 96 1.8 or 9 I do not recurred bn that engine but it is the Zetec to gasoline because it turns out that the problem is in the vulvo or temperature sensor that controls the advance automatically turns Vulvoco to check it I heat him and if he works in fact, well and when he is connected I put current or earth directly from the battery and it turns out that TM, the bn fan works but constant without being in automatic

You have not checked if it depends on relay ... Use a scanner and guide with the Pids map or data line, with the open switch without turning the engine and hole of the covered sensor, manually heats the disdain sensor ((with a hair dryer, heat pistol or a lighter) and check at what active temperature and deactivate and thus check if the sensor works It lies elsewhere ... I hope it helps you

Possibly, the sensor does not reach temperature and is not activated. The sensory has three or two cables, if it is three it has two speeds, apart from these cars they have a unit that controls the fans but I do not think that is the problem I think more of sensor or lack of temperature.
Another thing the thermostat works well check it and in the sensor the capabilities and lon maxim and minimum temperature and could guide you with those.- Greetings Alf

Be careful with this topic, you have to differentiate very well between temperature bulb and temperature sensor, in the Ztec Rocam engines, there is no temperature bulb if not temperature sensor, now this sends signal to the ECU and it is responsible for activating the fan, if it does not From a bulb for the drive system, it is normal for the temperature sensor to disconnect the fan sensor through the ECU and activate.
