Genuine Volvo 740 Coolant Temperature Sensor

The Volvo 740 depends on a number of components so as to guarantee better engine performance and one of those is the Coolant Temperature Sensor. This element is screwed directly into the coolant passages, and is exposed to the engine coolant to offer real-time temperature information to the engine control module. The Coolant Temperature Sensor is a thermistor, a negative temperature coefficient thermistor, that has a lower electrical resistance with a rise in temperature. The engine control module supplies the Volvo 740 Coolant Temperature Sensor with a 5-volt reference voltage, and the resistance of the sensor causes the voltage to be smaller than the input. This return voltage is then applied to calculate the exact temperature by the module. The sensor data is crucial in the Volvo 740 engine control module to control various functions of the vehicle. It enables the module to adjust the injector pulse width, with a longer on-time when the engine is cold and shorter as the engine heats up, to a richer mixture. The sensor also controls the idle speed by increasing idle speed when the engine is cold to avoid stalling and switching the electric cooling fan on and off. The data is also important in allowing certain component functions only when the engine is hot as in the case of the exhaust gas recirculation system, the evaporative emissions control purge valve, and the transmission torque converter clutch. The Volvo system keeps a check on the coolant temperature and maintains maximum performance and avoids overheating.
