IGNITION SIGNAL
Component Function CheckINFOID:0000000009462445
1.INSPECTION START
Turn ignition switch OFF, and restart engine.
Does the engine start?
YES-1 >> With CONSULT: GO TO 2.
YES-2 >> Without CONSULT: GO TO 3.

.
2.CHECK IGNITION SIGNAL FUNCTION
With CONSULT
1. Perform “POWER BALANCE” in “ACTIVE TEST” mode with CONSULT.
2. Check that each circuit produces a momentary engine speed drop.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-511, "Diagnosis Procedure"
.
3.CHECK IGNITION SIGNAL FUNCTION
Without CONSULT
1. Let engine idle.
2. Read the voltage signal between ECM harness connector terminals with an oscilloscope.
*1: Except for California
*2: For California
NOTE:
The pulse cycle changes depending on rpm at idle.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-511, "Diagnosis Procedure"
.

SENSOR POWER SUPPLY 2 CIRCUIT
DescriptionINFOID:0000000009462458
ECM supplies a voltage of 5 V to some of the sensors systematically divided into 2 groups, respectively.
Accordingly, when a short circuit develops in a sensor power source, a malfunction may occur simultaneously
in the sensors belonging to the same group as the short-circuited sensor.
Sensor power supply 1
• APP sensor 1
• Battery current sensor
• CKP sensor (POS)
• Intake manifold runner control valve position sensor
• Refrigerant pressure sensor
• TP sensor
NOTE:
If sensor power supply 1 circuit is malfunctioning, DTC P0643 is displayed.
Sensor power supply 2
• APP sensor 2
• CMP sensor (PHASE)
• EVT control position sensor
• EOP sensor
• MAF sensor
Diagnosis ProcedureINFOID:0000000009462459
1.CHECK APP SENSOR 2 POWER SUPPLY CIRCUIT-1
1. Turn ignition switch OFF.
2. Disconnect accelerator pedal position (APP) sensor harness connector.
3. Turn ignition switch ON.
4. Check the voltage between APP sensor harness connector and ground.
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK APP SENSOR 2 POWER SUPPLY CIRCUIT-2
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between APP sens or harness connector and ECM harness connector.
*1: Except for California
*2: For California
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair open circuit.

EVAP LEAK CHECK
2. Apply battery voltage between the terminals of EVAP
canister vent control valve to make a closed EVAP
system.
3. To locate the leak, deliver positive pressure to the EVAP system until pressure gauge points reach 1.38 to
2.76 kPa (0.014 to 0.028 kg/cm
2, 0.2 to 0.4 psi).
4. Remove EVAP service port adapter [commercial service tool: (J-41413-OBD)] and hose with pressure
pump.
5. Locate the leak using a leak detector [commercial service tool: (J-41416)]. Refer to EC-62, "EVAPORATIVE EMISSION SYS-
TEM : System Description".
