Sonata GL V6-2.5L (1999)
Ignition Coil: Testing and Inspection
IGNITION COIL
1. Measurement of the primary coil resistance
Measure the resistance between connector terminals 1 and 2 (the coils at the No.3 and No.6 cylinder sides) of the ignition coil, and between
terminals 1 and 3 (the coils at the No.1 and No.4 cylinder sides), and between terminals 1 and 4 (the coils at the No.2 and No.5 cylinder sides)
Standard value: 0.74 +/- 10% (Ohm)
2. Measurement of the secondary coil resistance
Measure the resistance between the high-voltage terminal for the No.3 and No.6 cylinders, between the high-voltage terminals for the No.1 and
No.4 cylinders and between the high- voltage terminals for the No.2 and No.5 cylinders.
Standard value: 13.3 +/- 15% (kOhm)
CAUTION: Be sure, when measuring the resistance of the secondary coil, to disconnect the connector of the ignition coil.
