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
INFOID:0000000004349464
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
NO
>> INSPECTION END
