DTC Description
INFOID:0000000010703034
DTC DETECTION LOGIC
POSSIBLE CAUSE
• Harness or connectors (Intake manifold runner control valve motor circuit is open.)
• Intake manifold runner control valve motor
FAIL-SAFE
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.
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:
Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
>> GO TO 2.
DTC No.

DTC detecting condition
P2008
TUMBLE CONT/V
(Intake manifold runner control valve)
Intake manifold runner control valve motor signal circuit is open.
Engine operating condition in fail-safe mode
Fail safe mode
Vehicle behavior
Traveling con-
trol mode
Accelerator an-
gle variation
control
ECM controls the accelerator pedal depression speed to make it slower than actual speed. This
causes a drop in accelerating performance and encourages the driver to repair malfunction.
NOTE:
ECM does not control the accelerator pedal releasing speed.
Engine output
control
ECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle
speed to encourage the driver to repair malfunction.
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
control mode
Stratified charge
combustion
control at start-
ing
No stratified charge combustion at starting (cold start).
Idle speed con-
trol
Stops feedback control of idle speed and controls with specified speed.
Recovery speed
control at decel-
erating
Stops recovery speed control by the fuel cut at decelerating and controls with specified speed.
Idle neutral con-
trol
Stops idle neutral control.
Ignition timing
correction con-
trol
Partially controls ignition timing control.
Retardation
control
Controls ignition timing delay control in the intermediate water temperature range.

2.
PERFORM DTC CONFIRMATION PROCEDURE
1.
Turn ignition switch ON and wait at least 5 seconds.
2.
Revving engine from idle up to 4,000 rpm under no load after warming up, then return to idling.
3.
Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
ECM-344, "Diagnosis Procedure"
.
NO-1
>> To check malfunction symptom before repair: Refer to
GI-41, "Intermittent Incident"
.
NO-2
>> Confirmation after repair: INSPECTION END
Diagnosis Procedure
INFOID:0000000010703035
1.
