Ignition Coil With Power Transistor DISTRIBUTORLESS Ignition System
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.
CHECKING IGNITION COIL RESISTANCE (ALTIMA & SENTRA 2.5L)
| Measure Between Terminals | Specification @ 77°F (25°C) |
|---|---|
| 1 & 2 | Except Zero Or Infinity |
| 1 & 3 | Except Zero |
| 2 & 3 | Except Zero |
CHECKING IGNITION COIL RESISTANCE (I35, MAXIMA, PATHFINDER & QX4)
| Measure Between Terminals | Specification @ 77°F (25°C) | Result |
|---|---|---|
| 2 & 3 | Zero | No Good |
| 2 & 3 | Not Zero | Good |
