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

DTC P2009 - Intake Manifold Runner Control Circuit Low (Bank 1)

DTC 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.

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 and ECT / Trouble Codes.
(f) Read DTCs.
Result:






B -- CHECK FOR INTERMITTENT PROBLEMS
A -- REPLACE ECM
