How should the ECT sensor be handled and installed to ensure proper operation of the fuel injection system on Hyundai Sonata?

Handle the ECT sensor with care, as damage will affect the operation of the entire fuel injection system. The ECT sensor is located at the driver's end of the engine near the thermostat housing for 2010 and earlier models. Begin by disconnecting the cable from the negative battery terminal and partially draining the cooling system. Next, disconnect the electrical connector from the ECT sensor, unscrew the sensor from the coolant passage, and avoid sealing the threads of the new sensor with Teflon tape, as this will interfere with grounding; instead, apply a small amount of liquid sealer to the threads before installation. Installation is the reverse of removal, ensuring the sensor is tightened securely, followed by refilling the cooling system. For 2011 and later models, the ECT sensor is located on the back side of the cylinder head. Remove the spring clip and pull the sensor from the coolant temperature control housing, then install the new sensor in reverse order, securing it with the spring clip and refilling the cooling system afterward.
