Cold Diesel and Gasoline Start in cold.

Greetings to this community

I have had problems with cold starts both diesel and gasoline.
According to my incomplete knowledge, the ECU takes information on the temperature probe (NTC) of the engine cooling and admission air temperature probe for cold starting "if I am not equivalent and I do not know if I leave something safe than in new systems if."

In gasoline vehicles the module injects more gasoline and the idle rises.

In Diesel controls the time of the heat of heater to heat the cameras (apart from new systems that heat the diesel).

If I disconnect these gasoline sensors I do not observe the idle to increase for wanting to port the cold start but the fans jump (Opel Astra G Z16SE)

and in the diesel what are the sensors that inform the module for the heat of heating acts? "Temperature sensor (NTC) refrigerant liquid" and which one?

You could idice me and help me.
How to try the cold start of gasoline. Could you cheat the ECU with resistors the sensors? Although disconnecting only the fan jumps "infinite resistance is created"

and how to deceive the Diesel ECU to act in the relay of heaters? since the hot engine the ECU recive information of the hot engine and stops acting the relay.

Sorry for the will
a health and thank you all.

Hello Piter112, with respect to: "In gasoline vehicles the module injects more gasoline and the idle rises" this happened in old systems in the absence of the parameter engine temperature. The module assumes the cold Engine, therefore enrich and simply rise the revolutions, the electrventilers do not turn on when disconnecting the temperature sensor because the ventilation function is controlled by A bulb that was usually located on the radiator.

From this: "If I disconnect these sensors in gasoline I do not observe the idle to increase for wanting to port the cold start but the fans jump (Opel Astra G Z16se)" is the normal behavior of the modern system by remaining without the parameter temperature of the refrigerant, because in these the lost signal is replaced by a value taken in concordance with the rest of the other parameters. EJ Air Temperature, Oil Temperature, Calculated load, Time Strawed from starting, accelerator position, vehicle speed. gear march, atmospheric pressure, oxygen sensor, etc., etc. From this the module calculates a statistically more likely value for the lost signal eg: 80 degrees, although the quality of control degrades is not as much as in the previous case. The engine control module when not knowing what temperature is it on the electro -seasons to avoid overweight, because in this case it is the ECU Motor that in charge of the function and ventilation speed taking into account basically temperature of the refrigerant.

With respect to: "You could idice me and help me.

Although disconnecting only the fan jumps" infinite resistance is created "it can be done with a potentiometer or variable resistance, coordinated to the connection of the temperature sensor. That if be careful with the resistive ranges and when applying.

In modern diesel, the camera preheating function is generally controlled by a prealesty control module which calculates the time of acuedo to information disseminated by other modules. However, there are other important parameters such as the battery voltage, its temperature, presence of other electric consumers, etc. which can be delivered by other modules
. News are generally costs more, although you can always, mainly due to the quality and quantity of info they have to calculate the most suitable responses.
