P2004 TUMBLE CONTROL VALVE
Description
INFOID:0000000004349459
Tumble control valve (3) is installed in the intake manifold adapter
(1).
Tumble control valve actuator (2) is connected to the front end of the
valve shaft.
Tumble control valve actuator consists of motor and position sensor,
etc.
The motor opens or closes the valve by the output signal of the
ECM.
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 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.
• Always perform the test at a temperature above 0
°C (32°F)
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT-III
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-III.
3. Make sure that “COOLAN TEMP/S” indicates between 5
°C (41°F) to 60°C (140°F).
If not, cool engine down or warm engine up until “COOLAN TEMP/S” indicates between 5
°C (41°F) to
60
°C (140°F). Then go to the following steps.
