Frontier SE Crew Cab 4WD V6-3.3L (VG33E) (2000)
Distributor: Testing and Inspection
IGNITION COIL & POWER TRANSISTOR
The power transistor switches on and off the ignition coil primary circuit according to the ECM signal. As the primary circuit is turned on and off, the
proper high voltage is induced in the secondary circuit. The distributor is not repairable except for the distributor cap and rotor head.
POWER TRANSISTOR
1. Disconnect camshaft position sensor & power transistor harness connector and ignition coil harness connector.
2. Check power transistor resistance between terminals 2 and 8.
If NG, replace distributor assembly.
Step 10
IGNITION COIL
1. Disconnect ignition coil harness connector.
2. Check resistance as shown in the figure.
Terminal
Resistance [at 25°C (77°F)]
7 - 8 (Primary coil)
0.5 - 1.0 ohms
7 - 9 (Secondary coil) Approximately 12 K Ohms
For checking secondary coil, remove distributor cap and measure resistance between coil tower metal tip 9 and terminal. If NG, replace distributor
assembly as a unit.
