DESCRIPTION
The ECM activates the DC motor for the tumble control valve, which opens and closes the tumble control valve. The ECM activates the DC motor based on engine speed, coolant temperature, intake air temperature and other conditions.
DTC No. |
DTC Detection Condition |
Trouble Area |
---|---|---|
P2009 |
Both of the following conditions continue for 1 second (1 trip detection logic): (a) The output duty of the DC motor for the tumble control valve is 34% or higher. (b) The current of the DC motor for the tumble control valve is below 0.35 A. |
|
P2010 |
Either of the following conditions continues for 6 times or more (1 trip detection logic): (a) The motor drive IC is overcurrent. (b) The motor drive IC overheats. |
MONITOR DESCRIPTION
When the voltage of the DC motor deviates from the standard range, the ECM determines that a malfunction has occurred and outputs a DTC.

CAUTION / NOTICE / HINT
HINT:
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. |
INSPECT INTAKE AIR CONTROL VALVE ACTUATOR (FOR TUMBLE CONTROL VALVE) |
(a) Inspect the intake air control valve actuator (See page ).
NG |
REPLACE INTAKE AIR CONTROL VALVE ACTUATOR (FOR TUMBLE CONTROL VALVE) |
|
2. |
INSPECT INTAKE MANIFOLD (TUMBLE CONTROL VALVE OPERATION) |
(a) Inspect the intake manifold (See page
).
NG |
REPLACE INTAKE MANIFOLD |
|
3. |
CHECK HARNESS AND CONNECTOR (ECM - INTAKE AIR CONTROL VALVE ACTUATOR) |
NG |
REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
4. |
CHECK WHETHER DTC OUTPUT RECURS (DTC P2009 OR P2010) |
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Clear the DTCs (See page ).
(e) Turn the ignition switch off and wait for at least 30 seconds.
(f) Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
(g) Enter the following menus: Powertrain / Engine / Trouble Codes.
(h) Read the DTCs.
