P1320

COMPONENT DESCRIPTION




Ignition coil & power transistor
The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit.

DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

NOTE:
- If "DIAGNOSTIC TROUBLE CODE 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 P0335, P0340 or P1336, perform trouble diagnosis for DTC P0335, P0340 or P1336 first.

With Consult
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT-II.
3. Start engine and wait at least 4 seconds. (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".

OR

With Generic Scan Tool
Follow the procedure "With CONSULT-II" above.

DIAGNOSTIC PROCEDURE

COMPONENT INSPECTION

Ignition Coil With Power Transistor:

Ignition coil with power transistor
1. Disconnect ignition coil with power transistor harness connector.
2. Check ignition coil with power transistor for resistance between terminals (3) and (2).
If NG, replace ignition coil with power transistor assembly.
