• 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

EVAP LEAK CHECK
Work ProcedureINFOID:0000000009462869
CAUTION:
• Never use compressed air or a high pressure pump.
• Never exceed 4.12 kPa (0.042 kg/cm
2, 0.6 psi) of pressure in EVAP system.
NOTE:
• Do not start engine.
• Improper installation of EVAP service port adapter (com mercial service tool) to the EVAP service port may
cause a leakage.
WITH CONSULT
1. To locate the EVAP leakage, install EVAP service port adapter (commercial service tool) and pressure pump to EVAP service
port.
2. Turn ignition switch ON.
3. Select the “EVAP SYSTEM CLOSE” of “WORK SUPPORT MODE” with CONSULT.
4. Touch “START”. A bar graph (Pressure indicating display) will appear on the screen.
5. Apply positive pressure to the EVAP system until the pressure indicator reaches the middle of the bar graph.
6. Remove EVAP service port adapter (commercial service tool) and hose with pressure pump.
7. Locate the leakage using a leakage detector (commercial ser- vice tool). Refer to EC-580, "EVAPORATIVE EMISSION SYS-
TEM : System Description".
WITHOUT CONSULT
1. To locate the EVAP leakage, install EVAP service port adapter
(commercial service tool) and pressure pump to EVAP service
port.
2. Apply battery voltage between the terminals of EVAP canister vent control valve to ma ke a closed EVAP system.
3. To locate the leakage, deliver positive pressure to the EVAP sys- tem until pressure gauge points r each 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) and hose with pressure pump.
