Component Inspection

INFOID:0000000004349462

1.

CHECK TUMBLE CONTROL VALVE

 With CONSULT-III

1. Turn ignition switch OFF.

2. Remove intake manifold adapter. Refer to 

EM-26, "Removal and Installation"

.

3. Visually check the valve for damage and check if foreign matter is caught between the valve and the

housing.

4. Connect tumble control valve actuator harness connector.

5. Turn ignition switch ON.

6. Perform “TUMBLE CONTROL VALVE” in “ACTIVE TEST” mode with CONSULT-III.

7. Touch “ON/OFF” and check that the valve opens and closes.

 Without CONSULT-III

1. Turn ignition switch OFF.

2. Remove intake manifold adapter. Refer to 

EM-26, "Removal and Installation"

.

3. Visually check the valve for damage and check if foreign matter is caught between the valve and the

housing.

4. Supply tumble control valve actuator terminals with battery voltage within 2 seconds and check operation.

CAUTION:

Do not apply 12V DC continuously for 30 seconds or more. Doing so may result in damage to the

coil in tumble control valve motor.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace intake manifold adaptor.

P2014 TUMBLE CONTROL VALVE POSITION SENSOR

P2014 TUMBLE CONTROL VALVE POSITION SENSOR

Description

INFOID:0000000004349463

Tumble control valve position sensor is built into the tumble control

valve actuator (2).

The sensor consists of a permanent magnet and Hall IC. It senses

the valve shaft movement and feeds the voltage signals to the ECM.

DTC Logic

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at

least 10 seconds before conducting the next test.

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is more than 11V at idle.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start engine and let it idle for 5 seconds.

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

YES

>> Go to 

EC-414, "Diagnosis Procedure"

.

NO

>> INSPECTION END
