Where is the coolant temperature sensor located on an engine?
The readings produced from the coolant temperature sensor are transmitted to the engine control unit, where they are utilized as data for regulating and maintaining the proper ignition time and the optimal fuel injection through the computerized approach. The engine coolant temperature sensor is usually located on the engine block or cylinder head.
How can I check the idle air control?

If this tube becomes loose or broken it can leak un-metered air into the engine effectively causing an unbalance (via the mass air flow MAF sensor) in the computer system which can produce fast or slow idle.
How does the coolant temperature sensor on a Ford vehicle work?
The coolant temperature sensor on your Ford vehicle is a thermistor, which means that its resistance changes with temperature. Here in a nutshell, is how the engine coolant temperature sensor works: The engine coolant (ECT) temperature sensor has two wires.
How can I tell if my coolant temperature sensor is bad?
To diagnose the coolant temperature sensor, you need a repair manual for your car model to find what measurement values you should expect from the coolant temperature sensor. Connect an OBD2 Scanner and look for related trouble codes. Check the live data to see the temperature from the sensor.
Can a faulty coolant sensor cause a Toyota Camry to bog down?
In this video I show you how to replace the Engine Coolant Temperature Sensor for your Toyota Camry. This faulty piece can cause your car to idle terribly, bog down while accelerating, and/or engine cut off.
