P1320

Component Description




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.

NOTE: The rotor screw which secures the distributor rotor head to the distributor shaft must be torqued properly.

Tightening Torque: 3.6 ± 0.3 N.m (37 ± 3 kg-cm, 32 ± 3 in-lb)

DTC Confirmation Procedure

NOTE:
- If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.
- If DTC P1320 is displayed with DTC P0340, perform trouble diagnosis for DTC P0340 first.

With CONSULT-II
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT-II.




3. Start engine. (If engine does not run, turn ignition switch to "START" for at least 5 seconds.)
4. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.

With GST
Follow the procedure "With CONSULT-II".

Component Inspection

IGNITION COIL







1. Disconnect distributor harness connector.




2. Check resistance as shown in the figure.
For checking secondary coil, remove distributor cap and measure resistance between coil tower metal tip 9 and terminal 7. If NG, replace distributor assembly as a unit.

POWER TRANSISTOR




1. Disconnect distributor harness connector.




2. Check power transistor resistance between terminals 2 and 8.

If NG, replace distributor assembly.

RESISTOR




1. Disconnect resistor harness connector.
2. Check resistance between terminals 1 and 2.
Resistance: Approximately 2.2 kohm [at 25 °C (77 °F)]
If NG, replace resistor.
