Sonata GLS V6-2.5L (2000)
Using HI-SCAN
NOTE:
1. The injector drive time is when the supply voltage is 11 V and the cranking speed is less than 250 rpm.
2. When engine coolant temperature is lower than 0°C (32°F), the ECM fires all four cylinders simultaneously.
3. When the vehicle is new (within initial operation of about 500 km [300 miles]), the injector drive time may be about 10% longer.
Using stethoscope and voltmeter
Operation Sound Check
1. Using a stethoscope, check the injectors for clicking sound at idle. Check that the sound is produced at shorter intervals as the engine speed
increases.
NOTE: Ensure that the sound from an adjacent injector is not being transmitted along the delivery pipe to an inoperative injector.
