Ignition Coil With Power Transistor DISTRIBUTORLESS Ignition System
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 Nissan Xterra, 2003 Nissan Sentra, 2003 Nissan Pathfinder, 2003 Nissan Murano, and 2003 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) table, CHECKING IGNITION COIL RESISTANCE (MAXIMA, PATHFINDER) table or CHECKING IGNITION COIL RESISTANCE (SENTRA 1.8L) table. See Figure.
