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
2, −1.93 psi)] with fuel gauge retainer
remaining open and check that the pressure is applicable.

SENSOR POWER SUPPLY2 CIRCUIT
DescriptionINFOID:0000000009462861
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
• Accelerator pedal position (APP) sensor 1
• Camshaft position (CMP) sensor (PHASE)
• Electric throttle control actuator
• Battery current sensor
NOTE:
If sensor power supply 1 circuit is malfunctioning, DTC P0643 is displayed.
Sensor power supply 2
• Accelerator pedal position (APP) sensor 2
• Crankshaft position (CKP) sensor (POS)
• Refrigerant pressure sensor
• EVAP control system pressure sensor
• Engine oil pressure sensor
