DTC P0011 IVT CONTROL
DescriptionINFOID:0000000001702617
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN communication line.
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve. The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine
coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control sole-
noid valve depending on driving status. This makes it possible to control the shut/open timing of the intake
valve to increase engine torque in low/mid speed range and output in high-speed range.

PRECAUTIONS
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.
Precaution for Drain CoolantINFOID:0000000001702463
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000001702464
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000001702465
• When instructed to use special service tools, use the specified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000001702466
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000001702467
• Use torque wrench to tighten bolts or nuts to specification.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
• Release air within route after draining coolant.
• Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for
leakage.
Parts Requiring Angular TighteningINFOID:0000000001702468
• Use an angle wrench for the final tightening of the following engine parts:
- Cylinder head bolts
- Camshaft sprocket (INT)
- Main bearing cap bolts
- Connecting rod cap nuts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)

WARNING:
• Situate the vehicle on a flat and solid surface.
• Place chocks at front and back of rear wheels.
• Attach proper slingers and bolts described in PARTS CATALOG if engine slingers are not equipped.
CAUTION:
• Always be careful to work safely, avoid forceful or uninstructed operations.
• Do not start working until exhaust system and coolant are cool enough.
• If items or work required are not covered by the engine section, follow the applicable procedures.
• Always use the support point specified for lifting.

• If measured value is out of the standard, replace flywheel.
Movement Amount in Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction with the following procedure:
1. Install clutch cover bolt (1) to clutch cover mating hole, and
place a torque wrench (A) on the extended line of the flywheel
(2) center line.
• Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it
from loosening.
2. Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
3. Apply a force of 9.8 N·m (1.0 kg-m, 87 in-lb) in each direction,
and mark the movement amount on the mass on the transaxle
side.
4. Measure the dimensions of movement amounts “A” and “B” on
circumference of the flywheel on the transaxle side.
• If measured value is out of the standard, replace flywheel.Limit: 33.2 mm (1.307 in) or less.

INSPECTION AFTER REMOVAL
Wheel Hub and Knuckle Inspection
Check for any deformity, cracks, or other damage on the wheel hub assembly and knuckle, replace if neces-
sary.
CAUTION:
The wheel hub assembly does not require maintenance. If any of the following symptoms are noted,
replace the wheel hub assembly.
• Growling noise is emitted from the wheel hub bearing during operation.
• Wheel hub bearing drags or turns roughly.
Ball Joint Inspection
Check boots of transverse link and steering outer socket ball joint for breakage, axial play, and torque. Refer to
FSU-14, "
Removal and Installation" transverse link and PS-13, "Disassembly and Assembly" steering outer
socket ball joint.
INSTALLATION
Installation is the reverse order of removal. Note the following:
• Perform the final tightening of each of parts under unladen conditions, which were removed when removing
wheel hub and bearing assembly and steering knuckle. Check the wheel alignment. Refer to RSU-2, "
Pre-
caution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"" .
• When installing disc rotor on wheel hub and bearing assembly,
align the marks.
(When not using the alignment mark, refer to BR-25, "
Disassembly
and Assembly of Brake Caliper Assembly" .)
