Genuine Lexus ES350 Coolant Temperature Sensor

The Lexus ES350 Coolant Temperature Sensor is applied to continuously monitor the heat in the coolant to provide the engine computer with real-time data to ensure smooth and safe engine operation. The sensor is a threaded NTC thermistor that is directly in a coolant passage and its resistance changes as the temperature increases, so the ECM reads the voltage it returns and knows immediately how warm the engine is. Every Coolant Temperature Sensor feeds the module the figures applied to widen the injector pulse if the ES350 is cold, raise idle speed, and switch the radiator fan by means of a relay once heat increases. Without the Coolant Temperature Sensor, the Lexus powertrain would be at risk of stalling, poor fuel economy, or overheating due to features such as EGR, purge control, and torque converter lockup which depend on accurate coolant readings. Earlier models applied a simpler coolant switch that only had an on-off ground for such devices as early fuel evaporation heaters, whereas today's Coolant Temperature Sensor provides a wide range of temperature signals, allowing later variants of the Lexus ES350 to have finer control. Both parts thread into the same passages but the switch only opens or closes at a set point while the modern Coolant Temperature Sensor is the source of continuous data, which gives the recent Lexus ES350 quicker response and better efficiency.
