WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2002 Nissan Xterra, 2002 Nissan Sentra, 2002 Nissan Quest, 2002 Nissan Pathfinder, and 2002 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition off. Disconnect suspect ignition coil 3-pin harness connector. Measure resistance between specified terminals. See CHECKING IGNITION COIL RESISTANCE (ALTIMA & SENTRA 2.5L) or CHECKING IGNITION COIL RESISTANCE (I35, MAXIMA, PATHFINDER & QX4) table. See Figure.
