2AZ-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P2009,P2010: 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 Intake Manifold Runner Valve (IMRV) motor is driven by the ECM. The IMRV motor opens and closes the IMRV.
When the current of the IMRV motor deviates from the standard range, the ECM determines that there is a malfunction.
The related DTCs are P2004 and P2006 P2004, and P2014, P2016 and P2017 P2014.
NOTICE: Do not disassemble the IMRV and the IMRV motor.

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 RUNNER VALVE ASSEMBLY (IMRV MOTOR RESISTANCE)




(a) Disconnect the C33 IMRV connector.
(b) Measure the resistance between the terminals.
Standard resistance:






NG -- REPLACE INTAKE MANIFOLD RUNNER VALVE ASSEMBLY
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (IMRV MOTOR - ECM)




(a) Disconnect the A24 ECM connector.
(b) Disconnect the C33 IMRV motor connector.
(c) Measure the resistance between the terminals of the wire harness side connectors.
Standard resistance (Check for open):






Standard resistance (Check for short):





(d) Reconnect the connectors.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. CHECK WHETHER DTC OUTPUT RECURS
(a) Clear the DTC DTC Check / Clear.
(b) Start the engine.
(c) Run the engine at more than 3,000 rpm.
(d) Turn the ignition switch off.
HINT: As running the engine to 3,000 rpm, the IMRV usually becomes fully opened. If the ignition switch is turned off under this condition, the IMRV is fully closed and then becomes half-opening angle.
(e) Read the DTC.
Result:






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