3.CHECK REFUELING EVAP VAPOR CUT VALVE
Without CONSULT
1. Turn ignition switch OFF.
2. Remove fuel tank. Refer to FL-10, "Removal and Installation"
.
3. Drain fuel from the tank as per the following:
- Remove fuel gauge retainer.
- Drain fuel from the tank using a handy pump into a fuel container.
4. Check refueling EVAP vapor cut valve for being stuck to close as per the following.
Blow air into the refueling EVAP vapor cut valv e (from the end of EVAP/ORVR line hose), and check that
the air flows freely into the tank.
5. Check refueling EVAP vapor cut valve for being stuck to open as per the following.
- Connect vacuum pump to hose end.
- Remove fuel gauge retainer with fuel gauge unit. Always replace O-ring with new one.
- Turn fuel tank upside down.
- Apply vacuum pressure to hose end [ −13.3 kPa ( −0.136 kg/cm
3, −1.93 psi)] with fuel gauge retainer
remaining open and check that the pressure is applicable.

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.
