P2008 INTAKE MANIFOLD RUNNER CONTROL VALVE EC-357 < DTC/CIRCUIT DIAGNOSIS > [MR20DD] C D E F G H I J K L M A EC N P O P2008 INTAKE MANIFOLD RUNNER CONTROL VALVE DTC Description INFOID:0000000010775253 DTC DETECTION LOGIC POSSIBLE CAUSE • Harness or connectors (Intake manifold runner control valve motor circuit is open.) FAIL-SAFE DTC CONFIRMATION PROCEDURE 1. PRECONDITIONING If DTC Confirmation Procedure has been previously conducted, always perform the following procedure Turn ignition switch OFF and wait at least 10 seconds. 2. Turn ignition switch ON. 3. Turn ignition switch OFF and wait at least 10 seconds. TESTING CONDITION: >> GO TO 2. DTC No. CONSULT screen terms (Trouble diagnosis content) DTC detecting condition P2008 TUMBLE CONT/V Intake manifold runner control valve motor signal circuit is open. Engine operating condition in fail-safe mode Fail safe mode Vehicle behavior Traveling con- Accelerator an- ECM controls the accelerator pedal depression speed to make it slower than actual speed. This Engine output ECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle Device fix mode • This mode fixes the IVT control solenoid valve and the EVT control solenoid valve in the refer- ence position. • The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens). Combustion Stratified charge No stratified charge combustion at starting (cold start). Idle speed con- Stops feedback control of idle speed and controls with specified speed. Recovery speed Stops recovery speed control by the fuel cut at decelerating and controls with specified speed. Idle neutral con- Stops idle neutral control. Ignition timing Partially controls ignition timing control. Retardation Controls ignition timing delay control in the intermediate water temperature range. |
