Ignition Coil/Power Transistor Resistance
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.
Disconnect ignition coil/power transistor harness connector. Measure resistance between terminals No. 3 (Red wire on I35, Maxima, Pathfinder and QX4, Green/White wire on Sentra) and No. 2 (Black wire). If resistance is zero ohms, replace ignition coil/power transistor.
