REFRIGERANT PRESSURE SENSOR

3. Check the voltage between refrigerant pressure sensor harness

connector and ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

DETECT MALFUNCTIONING PART

Check the following.

• Harness connectors E3, F1

• Junction block connectors E44, E45

• IPDM E/R harness connectors E18, E201

• Harness for open or short between ECM and refrigerant pressure sensor

>> Repair open circuit, short to ground or short to power in harness or connectors.

4.

CHECK REFRIGERANT PRESSURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between refrigerant pressure sensor harness connector and ECM harness connec-

tor.

4. Also check harness for short to ground and short to power.
Is the inspection result normal?

YES

>> GO TO 6.

NO

>> GO TO 5.

5.

DETECT MALFUNCTIONING PART

Check the following.

• Harness connectors E3, F1

• IPDM E/R harness connectors E18, E201

• Harness for open or short between ECM and refrigerant pressure sensor

>> Repair open circuit, short to ground or short to power in harness or connectors.

6.

CHECK REFRIGERANT PRESSURE SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1. Check the continuity between refrigerant pressure sensor harness connector and ECM harness connec-

tor.

2. Also check harness for short to ground and short to power.
Is the inspection result normal?

YES

>> GO TO 8.

NO

>> GO TO 7.

VARIABLE INDUCTION AIR SYSTEM

VARIABLE INDUCTION AIR SYSTEM

Description

INFOID:0000000010095238

Power Valves 1 and 2

The power valves 1 and 2 are installed in intake manifold collector and used to control the suction passage of

the variable induction air control system. They are set in the fully closed or fully opened position by the power

valve actuators 1 and 2 operated by the vacuum stored in the vacuum tank. The vacuum to power valve actu-

ators is controlled by the VIAS control solenoid valves 1 and 2.

Component Function Check

INFOID:0000000010095239

1.

CHECK OVERALL FUNCTION-I

 With CONSULT

1. Start engine and warm it up to the normal operating temperature.

2. Perform “VIAS S/V-1” in “ACTIVE TEST” mode with CONSULT.

3. Turn VIAS control solenoid valve 1 “ON” and “OFF”, and check that power valve actuator 1 rod moves.

 Without CONSULT

1. Start engine and warm it up to the normal operating temperature.

2. When revving engine up to 5,000 rpm quickly.

3. Check that power valve actuator 1 rod moves under the following conditions.

Is the inspection result normal?

1.

Power valve actuator 1

2.

Power valve actuator 1 rod

3.

Power valve actuator 2 rod
