Does the Elantra have sensor failure issues?

[CassidyFitz]

The Elantra may experience sensor failure issues. Automotive sensors serve as input devices for the vehicle's computer system, converting various operational parameters such as speed, temperature of different mediums, and engine operating conditions into electrical signals transmitted to the computer, ensuring the engine operates in its optimal state. The detection methods for automotive sensors are as follows: 1. Unplug the connector, turn the key to the second position, and use a voltmeter to measure and confirm that the power line has voltage output. 2. Use a multimeter to identify the ground wire. With the voltage setting, connect one probe to the confirmed power line and the other probe to the remaining two wires. The wire that shows voltage is the ground wire, and the remaining one is the signal wire. 3. Then, turn off the ignition, disconnect the signal wire, reconnect the connector, start the engine, and measure the voltage between the signal wire and the ground wire. There should be a signal voltage output, which should be less than the supply voltage. If there is no voltage, the sensor is likely damaged.
