P2006

2AR-FE ENGINE CONTROL: SFI SYSTEM: P2004, P2006: Intake Manifold Runner Control Stuck Open (Bank 1)
P2006 - Intake Manifold Runner Control Stuck Closed (Bank 1)

DESCRIPTION

The Tumble Control Valve (TCV) is built into the intake manifold. The intake air control valve actuator (for TCV) is composed of a position sensor and a DC motor. The DC motor opens and closes the TCV in response to signals from the ECM. The position sensor detects the opening angle of the tumble control valve.

When the tumble control valve is closed, the intake air tumble flow intensifies and negative pressure is generated between the tumble control valve and intake valve which atomizes the fuel. Combustion is enhanced and exhaust gas emissions are reduced at low temperatures.





HINT
When P2004 and/or P2006 is output, use the Techstream to confirm Intake Air Control Position while performing Control the IAC Duty Ratio of the Active Test.

MONITOR DESCRIPTION

When the ECM has requested a tumble control valve "close" operation but the actual tumble control valve opening angle is 17° or more for 10 seconds, DTC P2004 is stored. When the ECM has requested a tumble control valve "open" operation but the actual tumble control valve opening angle is less than 35° for 10 seconds, DTC P2006 is stored.

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 [A].

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

HINT
- Check for DTC P2004 at a coolant temperature of 30°C or less.
- Check for DTC P2006 at a coolant temperature of 80°C or higher.

8. Turn the ignition switch off.

9. Turn the ignition switch to ON, wait approximately 10 seconds, and then turn the ignition switch off. Repeat this procedure 3 times [B].

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

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: P2004 or P2006.

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.

WIRING DIAGRAM





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. CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2004 OR P2006)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

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

(e) Read the DTCs.

Result





HINT
If any DTCs other than P2004 or P2006 are output, troubleshoot those DTCs first.

B -- GO TO DTC CHART Engine Control - SFI System
A -- Continue to next step.

2. INSPECT INTAKE AIR CONTROL VALVE ACTUATOR (FOR TCV)

(a) Inspect the intake air control valve actuator (for TCV) Intake System.

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

3. 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.

4. CHECK WHETHER DTC OUTPUT RECURS (DTC P2004 OR P2006)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Clear the DTCs.

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

(f) Read the DTCs.

Result





B -- SYSTEM OK

A -- REPLACE ECM Removal
