P0075, P0081 IVT CONTROL SOLENOID VALVE
DescriptionINFOID:0000000003856523
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and let it idle for 5 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Go to EC-146, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003856525
1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect intake valve timing control solenoid valve harness connector.
3. Turn ignition switch ON.
4. Check the voltage between intake valve timing (IVT) control solenoid valve harness connector and ground
with CONSULT-III or tester.
Is the inspection result normal?
YES >> GO TO 2.

CYLINDER BLOCK
 If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer to
EM-130, "
ConnectingRodBearing".
Method of Using Plastigage
 Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
 Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install connecting rod bearings to connecting rod and connecting rod bearing cap, and tighten connecting
rod bolts to the specified torque. Refer to EM-110, "
Disassembly and Assembly" for the tightening proce-
dure.
CAUTION:
Never rotate crankshaft.
 Remove connecting rod bearing cap and bearings, and using the
scale on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
 Install main bearings (3) to cylinder block (1) and main bearing
caps (2), and main bearing cap bolts with main bearing beam to
the specified torque. Refer to EM-110, "
Disassembly and Assem-
bly" for the tightening procedure.
 Measure the inner diameter of main bearing with a bore gauge.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)
 If the calculated value exceeds the limit, select proper main bear-
ing according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-132, "
MainBearing".
Method of Using Plastigage
 Remove engine oil and dust on crankshaft journal and the surfaces of each bearing completely.
 Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install main bearing to cylinder block and main bearing caps, and tighten main bearing cap bolts with main
bearing beam to the specified torque. Refer to EM-110, "
Disassembly and Assembly" for the tightening pro-
cedure.
CAUTION:
Never rotate crankshaft.

MAIN BEARING CRUSH HEIGHT
 When main bearing cap is removed after being tightened to the
specified torque with main bearings (1) installed, the tip end of
bearing must protrude. Refer to EM-110, "
Disassembly and
Assembly" for the tightening procedure.
 If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
 When connecting rod bearing cap is removed after being tightened
to the specified torque with connecting rod bearings (1) installed,
the tip end of bearing must protrude. Refer to EM-110, "
Disassem-
bly and Assembly" for the tightening procedure.
 If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
 Measure the outer diameters (c), (d) at two positions as shown in
the figure.
 If reduction appears in (a) range, regard it (c).
 If it exceeds the limit (large difference in dimensions), replace main
bearing cap bolt with new one.

TIGHTENING TORQUE OF STANDARD BOLTS
DescriptionINFOID:0000000003852910
This vehicle has both new standard based on ISO* and previous standard bolts/nuts. There are some differ-
ences between these two types of bolts/ nuts; shape of the head, grade of strength, hexagonal width across
flats and the standard tightening torque.
 For guidance in discriminating, refer to GI-14, "
Tightening Torque Table (New Standard Included)".
 The new standard machine screws and tapping screws have a head of ISO standard torx recess.
 If the tightening torque is not described in the description or figure, refer to GI-14, "
Tightening Torque Table
(New Standard Included)".
*ISO: International Organization for Standardization
Tightening Torque Table (New Standard Included)INFOID:0000000003852911
CAUTION:
 The special parts are excluded.
 The bolts/nuts in these tables have a strength (discrimination) number/symbol assigned to the head
or the like. As to the relation between the strength grade in these tables and the strength (discrimi-
