P2009

4GR-FSE ENGINE CONTROL: SFI SYSTEM: P2009, P2010: Intake Manifold Runner Control Circuit Low (Bank 1)
P2010 - Intake Manifold Runner Control Circuit High (Bank 1)

DESCRIPTION

The ECM activates the intake air control valve actuator for Swirl Control Valve (SCV), which opens and closes swirl control valve. The ECM activates the DC motor based on engine speed, coolant temperature, engine load signals and other conditions.





MONITOR DESCRIPTION

When the voltage of the DC motor (intake air control valve actuator) deviates from the standard range, the ECM determines that a malfunction has occurred and sets a DTC.

CONFIRMATION DRIVING PATTERN

1. Connect the Techstream to the DLC3.

2. Turn the engine switch on (IG).

3. Turn the Techstream on.

4. Clear the DTCs. (even if no DTCs are stored, perform the clear DTC procedure) Reading and Clearing Diagnostic Trouble Codes.

5. Turn the engine switch off and wait for at least 30 seconds.

6. Turn the engine switch on (IG) and turn the Techstream on.

7. Enter the following menus: Powertrain / Engine / Data List / All Data / Coolant Temp.

8. Check that the coolant temperature is 60°C (140°F) or higher.

9. Wait approximately 10 seconds.

10. Enter the following menus: Powertrain / Engine / Trouble Codes.

11. Read Pending DTCs.

HINT
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.

12. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

13. Input the DTC: P2009 or P2010.

14. Check the DTC judgment result.





HINT
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.

15. If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

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 MANIFOLD (SWIRL CONTROL VALVE OPERATION)

(a) Inspect the intake manifold Intake System.

NG -- REPLACE INTAKE MANIFOLD Removal
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (ECM - INTAKE AIR CONTROL VALVE ACTUATOR) P2004

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. CHECK WHETHER DTC OUTPUT RECURS (DTC P2009 OR P2010)

(a) Connect Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(e) Turn the engine switch off and wait for at least 30 seconds.

(f) Turn the engine switch on (IG).

(g) Turn the Techstream on.

(h) Wait approximately 10 seconds.

(i) Enter the following menus: Powertrain / Engine / Trouble Codes.

(j) Read the DTCs.
