Hyundai Santa Fe Coolant Temperature Sensor

The Hyundai Santa Fe Coolant Temperature Sensor measures engine coolant heat and feeds real time data to the engine control module so the SUV can run smoothly and avoid overheating. Threaded into a coolant passage, this thermistor style Coolant Temperature Sensor uses a five volt reference signal, its resistance falling as temperature rises, letting the module fine tune fuel pulse width, spark timing, idle speed and electric fan operation. Earlier Santa Fe editions also employed a simpler coolant switch that only supplied an on off signal for devices like early fuel evaporation heaters, but the modern Coolant Temperature Sensor delivers a full temperature range that the computer needs for precise control. Because the data let the ECM decide when to enrich the mixture, raise cold idle and engage relays for high current parts, the Coolant Temperature Sensor indirectly protects the battery and prevents engine knock, making every Hyundai Santa Fe start, idle and cruise with confidence. If this sensor fails, a Hyundai may run rich, fans may stay on and the Santa Fe could overheat or stall until a critical Coolant Temperature Sensor failure is corrected. Regular coolant service and using genuine parts keep its thermistor accurate.

If you are looking for affordable high-quality OEM Hyundai Santa Fe Coolant Temperature Sensor, then you have come to the prime place. Our website provides a large amount of genuine Hyundai Santa Fe Coolant Temperature Sensor at unbeatable prices. All our parts come backed with the manufacturer's warranty.

Q: How should the Coolant Temperature Sensor be handled and installed to ensure proper operation of the fuel injection system on Hyundai Santa Fe?
A:
To avoid problems with the ECT sensor, one must avoid any physical contact with this part because any damage to it will result in a failure of the entire fuel injection system. The ECT sensor is Mounted at the driver end of the engine either in the thermostat housing or in the coolant passage as shown in fig 11. First, unplug the cable from the negative terminal and bleed the cooling system by draining a little amount of it. Then, remove the electrical connector of ECT sensor by pulling it off and then unscrew the sensor from the cylinder head. Do not screw tight the new ECT sensor's threads with teflon due to it; as this will affect the grounding you should apply little liquid sealer on the threads before screwing tightly. Last, installations; This is the opposite of the removal where it is made sure that the ECT sensor is well tightened and the cooling system is refilled.
