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 oft the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit.




CONSULT REFERENCE VALUE IN DATA MONITOR MODE
Specification data are reference values.




ECM TERMINALS AND REFERENCE VALUE
Specification data are reference values, and are measured between each terminal and (25) (ECM ground).




ON BOARD DIAGNOSIS LOGIC

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 10 seconds before conducting the next test.
- If both DTC P1320 (0201) and DTC P0340 (0101), P1335 (0407), P0335 (0802) or P1336 (0905) are displayed, perform TROUBLE DIAGNOSES FOR DTC P0340, P1335, P0335 or P1336 first.

With Consult



1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT.
3. Start engine. (If engine does not run, turn ignition switch to "START" at least 5 seconds.)
4. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

With Generic Scan Tools
1. Turn ignition switch "ON".
2. Start engine. (If engine does not run, turn ignition switch to "START" at least 5 seconds.)
3. Select MODE 7 with GST.
4. It 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

Without Scan Tools
1. Turn ignition switch "ON".
2. Start engine. (If engine does not run, turn ignition switch to "START" at least 5 seconds.)
3. Turn ignition switch "OFF", wait at least 10 seconds and then turn "ON".
4. Perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.
5. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

DIAGNOSTIC PROCEDURE




COMPONENT INSPECTION

Ignition coil with power transistor
1. Disconnect ignition coil with power transistor harness connector.

Ignition Coil Resistance:

2. Check ignition coil with power transistor for resistance between terminals (1) and (2).

Condenser



1. Disconnect condenser harness connector.
2. Check condenser continuity between terminals (1) and (2).
Resistance: Above 1 MOhm at 25 °C (77 °F)
