3.DETECT MALFUNCTION PART
Check the harness for open or short between intake valve timing control solenoid valve and ECM relay.
>> Repair harness or connectors.
4.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR
OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Disconnect ECM harness connector.
3. Check harness continuity between ECM terminal 107 and intake valve timing control solenoid valve termi-
nal 2. Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 5.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
5.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Refer to EC-1352, "
Component Inspection" .
OK or NG
OK >> GO TO 6.
NG >> Replace intake valve timing control solenoid valve.
6.CHECK CRANKSHAFT POSITION SENSOR (POS)
Refer to EC-1245, "
Component Inspection" .
OK or NG
OK >> GO TO 7.
NG >> Replace crankshaft position sensor (POS).
7.CHECK CAMSHAFT POSITION SENSOR (PHASE)
Refer to EC-1251, "
Component Inspection" .
OK or NG
OK >> GO TO 8.
NG >> Replace camshaft position sensor (PHASE).
8.CHECK CAMSHAFT (INTAKE)
Check the following.
●Accumulation of debris to the signal plate of camshaft rear end
●Chipping signal plate of camshaft rear end
OK or NG
OK >> GO TO 9.
NG >> Remove debris and clean the signal plate of camshaft
rear end or replace camshaft. Continuity should exist.

Diagnostic ProcedureEBS00NA3
1.CHECK OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch "ON".
2. Select "P/N POSI SW" in "DATA MONITOR" mode with CON-
SULT-II.
3. Check the "P/N POSI SW" signal under the following conditions.
Without CONSULT-II
1. Turn ignition switch "ON".
2. Check voltage between ECM terminal 43 and ground under the
following conditions.
OK or NG
OK >>INSPECTION END
NG >> GO TO 2.
2.CHECK GROUND CIRCUIT
1. Turn ignition switch "OFF".
2. Disconnect PNP switch harness connector.
3. Check harness continuity between PNP switch terminal 2 and body ground. Refer to Wiring Diagram.
4. Also check harness for short to power.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to power in harness or connectors.

PNP SWITCH
3. CHECK INPUT SIGNAL CIRCUIT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 43 and PNP switch terminal 1. Refer to Wiring Diagram.
3. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> Repair open circuit or short to power in harness or connectors.
4. CHECK PNP SWITCH
Refer to AT- 3 4 9 , "
PNP Switch" (A/T models) or MT-12, "PARK/NEUTRAL POSITION SWITCH" (M/T mod-
els).
OK or NG
OK >> GO TO 5.
NG >> Replace PNP switch.
5. CHECK INTERMITTENT INCIDENT
Refer to EC-1192, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
>>INSPECTION END Continuity should exist.

INJECTOR CIRCUIT
3. CHECK INJECTOR POWER SUPPLY CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect injector harness connector.
3. Turn ignition switch “ON”.
4. Check voltage between injector terminal 1 and ground with
CONSULT-II or tester.
OK or NG
OK >> GO TO 5.
NG >> GO TO 4.
4. DETECT MALFUNCTIONING PART
Check the following.
●Harness connectors M61, F41
●Harness connectors F1, F101
●Fuse block (J/B) connector M1
●10A fuse
●Harness for open or short between injector and fuse
>> Repair harness or connectors.
5. CHECK INJECTOR OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Disconnect ECM harness connector.
3. Check harness continuity between injector terminal 2 and ECM terminals 101, 102, 103, 104.
Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 7.
NG >> GO TO 6.
