P0078 EVT CONTROL SOLENOID VALVE

YES

>> GO TO 2.

NO

>> Replace exhaust valve timing control solenoid valve. Refer to 

EM-49, "Exploded View"

.

2.

CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-2

1. Remove exhaust valve timing control solenoid valve. Refer to 

EM-49, "Exploded View"

.

2. Provide 12 V DC between exhaust valve timing control solenoid

valve terminals 1 and 2, and then interrupt it. Check that the

plunger moves as shown in the figure.

CAUTION:

Do not apply 12 V DC continuously for 5 seconds or more.

Doing so may result in damage to the coil in exhaust valve

timing control solenoid valve.

NOTE:

Always replace O-ring when exhaust valve timing control

solenoid valve is removed.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace exhaust valve timing control solenoid valve. Refer to 

EM-49, "Exploded View"

P0101 MAF SENSOR

DTC Description

INFOID:0000000011277949

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (MAF sensor circuit is open or shorted.)

• Intake air leaks

• MAF sensor

• EVAP control system pressure sensor

• Intake air temperature sensor

• Sensor power supply 2 circuit

FAIL-SAFE

• Traveling control mode (Accelerator angle variation control)

• Traveling control mode (Engine output control)

• Device fix mode

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P0101 is displayed with other DTC, first perform the trouble diagnosis for other DTC.
Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

EC-96, "DTC Index"

.

NO

>> GO TO 2.

2.

PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-

dure before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

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

2. Drive the vehicle for at least 5 seconds under the following conditions:

CAUTION:

Always drive vehicle at safe speed.

NOTE:

• The gear must be fixed while driving the vehicle.

• Keep the accelerator pedal as steady as possible during cruising.

3. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Proceed to 

EC-202, "Diagnosis Procedure"

.

NO

>> INSPECTION END

DTC No.

EC-96, "DTC Index"

.

NO

>> GO TO 2.

2.

CHECK INTAKE SYSTEM

Check the following for connection.

• Air duct

• Vacuum hoses

• Intake air passage between air duct and intake manifold

YES

>> GO TO 3.

NO

>> Reconnect the parts.

3.

CHECK MASS AIR FLOW (MAF) SENSOR POWER SUPPLY

1. Turn ignition switch OFF.

2. Disconnect MAF sensor harness connector.

3. Turn ignition switch ON.

4. Check the voltage between MAF sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 4.

4.

CHECK SENSOR POWER SUPPLY 2 CIRCUIT

Perform 

EC-487, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> Perform the trouble diagnosis for power supply circuit.

NO
