4GR-FSE ENGINE CONTROL SYSTEM: 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 Swirl Control Valve (SCV), which opens and closes SCV. The ECM activates the DC motor based on engine rpm, coolant temperature, engine load signals and other conditions. When the voltage of the DC motor deviates from the standard range, the ECM determines that a malfunction has occurred and outputs a DTC.
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
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) DTC Check / Clear.
- Turn the engine switch off and wait for 30 seconds.
- Turn the engine switch on (IG) and turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Data List / All Data / Coolant Temp.
- Check that the coolant temperature is 60°C (140°F) or higher.
- Wait approximately 10 seconds [A].
- Enter the following menus: Powertrain / Engine / Trouble Codes.
- Read the DTC [B].
HINT
- If a DTC is output, the system is malfunctioning.
- If a DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P2009 or P2010.
- Check the DTC judgment result.
HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows INCOMPLETE or UNKNOWN, perform step [A] again.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Check the DTC judgment result.
HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.
- If the test result is INCOMPLETE or UNKNOWN and no 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 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction Freeze Frame Data.
PROCEDURE
1. INSPECT INTAKE MANIFOLD (SCV OPERATION)
(a) Inspect the swirl control valve Testing and Inspection.
NG -- REPLACE INTAKE MANIFOLD
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (ECM - SCV)
(a) Disconnect the E6 ECM connector.
(b) Disconnect the E53 DC motor for SCV connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance (Check for open):
Standard resistance (Check for short):
(d) Reconnect the ECM connector.
(e) Reconnect the DC motor for SCV connector.
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 tester on.
(d) Clear DTCs.
(e) Enter the following menus: Powertrain / Engine / Trouble Codes.
(f) Read DTCs.
Result:
B -- CHECK FOR INTERMITTENT PROBLEMS
A -- REPLACE ECM Removal
