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
Diagnosis ProcedureINFOID:0000000009462862
1.CHECK SENSOR POWER SUPPLY 1
1. Turn ignition switch OFF.
2. Disconnect ECM harness connectors
3. Turn ignition switch ON.
4. Check the voltage between ECM harness connector and ground.
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-43, "Intermittent Incident".
NO >> GO TO 2.
2.CHECK SENSOR POWER SUPPLY 2 CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect following sensors harness connector.
3. Check harness for short to power and short to ground, between the following terminals.

EVAP LEAK CHECK
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.
