Code 0201

COMPONENT DESCRIPTION

IGNITION COIL & POWER TRANSISTOR (BUILT INTO DISTRIBUTOR)
The ignition coil is built into distributor. The ignition signal from the ECM is sent to the power transistor. The power transistor switches on and off the ignition coil primary circuit. As the primary circuit is turned on and oft, the proper high voltage is induced in the coil secondary circuit.
The distributor is not repairable and must be replaced as an assembly except distributor cap and rotor head.




CONSULT Reference Value in Data Monitor Mode







ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and 43 (ECM ground).




ON BOARD DIAGNOSIS LOGIC

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 (0201) is displayed with P0340 (0101), perform trouble diagnosis for DTC P0340 first.




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

With GST
1. Turn ignition switch "ON".
2. Start engine and wait at least 4 seconds. (If engine does not run, turn ignition switch to "START" at least 5 seconds.)
3. Select MODE 3 with GST.
4. If 1St trip DTC is detected, go to "Diagnostic Procedure".

Without Scan Tools
1. Turn ignition switch "ON".
2. Start engine and wait at least 4 seconds. (If engine does not run, turn ignition switch to "START" at least 5 seconds.)
3. Turn ignition switch "OFF" and wait at least 5 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
1. Disconnect ignition coil harness connector.
2. Check resistance as shown in the image.
3. For checking secondary coil remove distributor cap.







4. Check resistance between ignition coil harness connector terminal 8 and coil tower metal tip 9 (secondary terminal) on the distributor head.
If NG, replace distributor.







POWER TRANSISTOR
1. Disconnect power transistor harness connector.
2. Check power transistor resistance between terminals 5 and 7.
If NG, replace distributor.




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