Genuine Volvo S40 Coolant Temperature Sensor

The Volvo S40 Coolant Temperature Sensor is an important item that relays information about the engine's coolant temperature, contributing to performance and overheating prevention. The Volvo S40 Coolant Temperature Sensor is threaded straight into the coolant passages to get accurate data. This sensor's exposed to coolant to aid the ECM. The data on temperature is utilized by the ECM to govern the fuel injection, ignition timings, etc. This often works as a thermistor. More specifically, it is a negative temperature coefficient thermistor which decreases its resistance with increase in temperature. The Volvo S40 Coolant Temperature Sensor receives a 5-volt reference voltage sent by the ECM, and the sensor resistance reduces the voltage that is sent back to the computer. The temperature is then calculated by the ECM from this return voltage. This temperature data is critical for varying the injector pulse width in order to enrich the mixture when the engine is cold and to reduce it when the engine is warmed. Also, the data is helps increase idle speed when cold to stop stalling and to switch the electric cooling fan on and off. The sensor, found in a Volvo vehicle, allows certain components, such as the exhaust gas recirculation system, the evaporative emissions-control purge valve and the transmission torque converter clutch to function only when the engine is warm. The present system provides a continuous temperature signal near the engine and for the various engine management strategies. Thus, all strategies can be executed as intended.
