There are a few different types of sensors that can cause stalling in a car, depending on the car model. One type is the mass airflow sensor, which measures the amount of air flowing into the engine. If this sensor isn't working properly, it can cause the engine to stall. Another type of sensor is the throttle position sensor, which tells the computer how far the accelerator pedal is being pressed. If this sensor isn't working correctly, it can also cause stalling. Other potential sensors are the engine temp sensor, MAP sensor, and intake air temperature sensor.
