Ignition Coil (Frontier & XTERRA)
Ignition coil is located in distributor. Turn ignition off. Disconnect distributor 2-pin harness connector (ignition coil connector). Remove distributor cap. For primary coil, measure resistance between distributor 2-pin connector terminals (component side). For secondary coil, measure resistance between distributor 2-pin connector terminal No. 7 and coil tower. See Fig 1. See IGNITION COIL RESISTANCE (FRONTIER & XTERRA) table. Replace distributor assembly, if resistance is not as specified.
IGNITION COIL RESISTANCE (FRONTIER & XTERRA)
| Application | Primary | Secondary | |
|---|---|---|---|
| Frontier & Xterra | |||
| 2.4L | Less Than 1 Ohm @ 77°F (25°C) | 7-13 K/Ohms @ 77°F (25°C) | |
| 3.3L | .5-1.0 Ohm @ 77°F (25°C) | About 12 K/Ohms @ 77°F (25°C) | |
