Does the coolant temp sensor control fuel into engine when cold?

The engine coolant temp (ECT) sensor monitors the engine temp and sends that info to the engine control module (ECM). The ECM takes in info from many sensors including the ECT to determine the correct air/fuel ratio for the conditions. So to answer your question, yes. The ECT sensor does play a part in fuel control.

Why is the engine temperature light on when the engine is cold?
Likely a faulty coolant temperature sensor. Change the sensor.
What does a Coolant Temperature Sensor do?
the coolant temp sensor( cts) reads the temp of the engine and adjust the fuel air mixture depending on the temp. if its cold out the sensor will adjust for more fuel to ease the start of the engine. ADDITIONAL: The Coolant Temperature Sensor measures the temp of the coolant, not the engine. The sensor controls the thermo fans on/off. depending upon temperature. The actual engine temperature sensor is on top of the engine and does not control the fans. If the fans do not switch on at any temperature, disconnect the 2 wire connector from the sensor (Usually at the bottom of the radiator) If fans start up with connector disconnected, replace the sensor.
Could the temp coolant sensor cause the truck to run cold?
The coolant sensor moniters the coolant temperature. A faulty thermostat could cause the engine to run cool.
Where is the choke located on 1998 Ford Windstar?
There is NOT a choke on any fuel injected engine. The coolant temperature sensor does the job of what used to be the choke. When the coolant in the engine is cold, the coolant temperature sensor tells the engine control module and it determines how rich or lean to make the engine run. You can use a scanner to see if it and all the other sensors are doing the job they are meant to perform.
What might be the problem of cold starting in 1997 Chevy blazer?
Engine coolant sensor may be bad
WHY Hard start 305 hot or cold tbi?
Try replacing the engine coolant temp sensor.
Why does a 1985 mercury marquis stall when shifted into gear with cold engine in cold weather but not in warm weather?
Faulty ECT (engine coolant temperature) sensor. Replace it.
How do the engine coolant sending unit and the coolant temperature sensor work together?
The sending unit is only to control the temperiture warning light/gauge on your dash. If you are referring to the sending unit in your overflow tank it just turns your low coolant light on. The temperiture sensor is used to feed engine temperiture data into the computer, to caculate how much fuel the engine will get during cold start up etc. It is simply input data for the computer.
Why does your cars hot cold meter not show you how hot your car really is?
The engine coolant temperature sensor is probably at fault.
How do you filling coolant?
Add coolant to the full cold line on the coolant reservoir when engine is cold.
What can cause the Coolant fans not to run at all not even in AC mode?
Cold engine, extremely cold weather, malfunctioning temp sensor, malfunctioning thermostat.
What would cause a Nissan starts when is cold but won't start it is hot?
Check the engine coolant temprature sensor it may be sending the wrong signals to the ECU making the ECU think the engine is cold and overfueling the engine.
