Help start in cold diesel and gasoline

A community health

in gasoline The ECU receives information from the coolant temperature sensor and air and equity temperature sensor orders the injectors to inject more fuel.

In the diesel the ECU receives information from the temperature sensor of the coolant and the temperature sensor of the air and the ECU activates the relay of the heater. (The new systems heat the fuel).

When disconnecting these sensors creates infinite resistance which informs the ECU Low temperature. Nooo ....?

In gasoline as Opel Astra G Z16se only the electro -ventilators jumps, the slowdown increase "Cold start" is not proven.

In the diesel to falsify the signal to the ECU to order the surge of heater. "In Peugeot they bridged a sensor to try that cold start."

For culture and saviduria, you could help me and tell me how to try that process in gas "start in cold" and in the diesel "signal action of relay relay"

a health and thank you very much to everyone

Hi Piter112, I do not understand your question, but I think that both in gasoline, and in diesel, it is the NTC probe that helps, in gasoline increases in injection, in diesel, activates the timer relier, if what you want is to simulate that the engine is cold, you will have to put a resistance on the tab of about 3k ohms, and if you want to simulate that it is hot, about 900 ohms, in some 900 ohms The gasoline temperature probe influences pump ... greetings!

Greetings community.

ISMAEL53 Perfect understanding and perfect explication, does the "NTC" refer is that of the contracuing liquid I understand clearly? And now it only remains to try.

As always infallible guys your aid.

Greetings and thank you all.

Hi Piter112, indeed, it is that of the Refigurer Liquid, for clarity: In some models (eg VW) you do not have to confuse the temperature probe that regulates so much progress and injection pulse, with the probe that sends a signal only to the thermometer of the instrument box, as well as the radiator electrovalve confuse them.Saludos !!

Again thank you very incredible your work with people like me inexperienced, I set up a potentiometer to my little one and I have managed to learn one more step

a health and thank you very much to everyone
