2AR-FE 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 DC motor for the intake air control valve actuator (for TCV), which opens and closes the Tumble Control Valve (TCV). The ECM activates the DC motor based on engine speed, coolant temperature, intake air temperature and other conditions.





MONITOR DESCRIPTION

When the voltage of the DC motor deviates from the standard range, the ECM determines that a malfunction has occurred and stores a DTC.

COMPONENT OPERATING RANGE





CONFIRMATION DRIVING PATTERN

1. Connect the Techstream to the DLC3.

2. Turn the ignition switch to ON.

3. Turn the Techstream on.

4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).

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

6. Turn the ignition switch to ON and turn the Techstream on.

7. Enter the following menus: Powertrain / Engine / Data List / 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 the 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 judgment result is INCOMPLETE or UNKNOWN and no pending DTC is output, perform a universal trip and check for permanent DTCs DTC Check / Clear.

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. Freeze frame data records the engine conditions when malfunctions are detected. 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 TCV)

(a) Inspect the intake air control valve actuator (for TCV) Testing and Inspection.

NG -- REPLACE INTAKE AIR CONTROL VALVE ACTUATOR (FOR TCV) Removal
OK -- Continue to next step.

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

(a) Disconnect the ECM connector.

(b) Disconnect the intake air control valve actuator connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance (Check for Open):





Standard Resistance (Check for Short):





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

3. 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 DTC Check / Clear.

(e) Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.

(f) Read the DTCs.
