• Measure the outer diameter of valve lifter using suitable tool (A).
VALVE LIFTER HOLE DIAMETER
Measure the diameter of valve lifter hole of cylinder head using suit-
able tool (A).
VALVE LIFTER CLEARANCE
• (Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)
• If out of the standard, referring to the each standard of
valve lifter outer diameter and valve lifter hole diame-
ter, replace either or both valve lifter and cylinder head.
INSPECTION AFTER INSTALLATION
Inspection of Camshaft Sprocket Oil Groove
CAUTION:
• Perform this inspection only when DTC P0011 or P 0014 is detected in self-diagnostic results of CON-
SULT and it is directed according to insp ection procedure of EC section. Refer to EC-168, "
Diagnosis
Procedure" (P0011) or EC-172, "Diagnosis Procedure" (P0014).
• Check when engine is cold so as to pr event burns from the splashing engine oil.
NOTE:
This section provides the inspection method of oil passage of cam sprocket on the intake side. For oil passage
on the exhaust side, the inspection proc edure must be changed as instructed below:
1. Check engine oil level. Refer to LU-7, "
Inspection".
2. Perform the following procedure so as to prevent the engine from being unintentionally started while checking.
a. Release the fuel pressure. Refer to EC-137, "
Work Procedure".
b. Remove intake manifold. Refer to EM-28, "
Removal and Installation".
Standard : Refer to
EM-117, "
Camshaft".
PBIC3185J
Standard : Refer to EM-117, "Camshaft".
PBIC3184J
Standard : Refer to EM-117, "Camshaft".
· Step 3 : Remove exhaust valve timing control solenoid valve. Refer to EM-60, "Exploded View".
· Step 4 : Crank engine, and then check that engine oil comes out from exhaust valve timing control solenoid
valve hole (A). End crank after checking.
·Step 5 Perform the following inspection if engine oil does not come out from exhaust valve timing control
solenoid valve oil hole of the cylinder head.
• Remove oil filter, and then clean it. Refer to
EM-60, "
Exploded View".
• Clean oil groove between oil strainer and exhaust valve timing control solenoid valve. Refer to
EM-60, "
Exploded View".
·Step 6 : Remove components between exhaust valve timing control solenoid valve and camshaft sprocket
(EXH), and then check each oil groove for clogging.

5. Using a suitable tool finish valve seat to the specified dimen-
sions. For dimensions, refer to MA-11, "
Fluids and Lubricants".
CAUTION:
When using a valve seat cutter, firmly grip the cutter handle
with both hands. Then, pr ess the contacting surface evenly
around the valve seat to cut in a single attempt. Improper
pressure or cutting several times may result in wavy valve
seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to "VALVE SEAT CONTACT".
VALVE SPRING SQUARENESS
• Set a tri-square (A) along the side of valve spring and rotate spring. Measure the maximum clearance between the top of spring and
tri-square.
• If it exceeds the limit, replace valve spring.
VALVE SPRING DIMENSIONS AND VALVE SPRING PRESSURE LOAD
• Check valve spring pressure with valve spring seat installed at the specified spring height.
CAUTION:
Do not remove valve spring seat from valve spring.
• If the installation load or load with valve open is out of the stan- dard, replace valve spring (with valve spring seat).
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks
at connection points.
• Start engine. With engine speed increased, che ck again for fuel leaks at connection points.
• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there are no l eaks of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

COMPONENT PARTS
Heated Oxygen Sensor 2
INFOID:0000000012431289
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the air fuel ratio (A/F) sensor 1
are shifted, the air-fuel ratio is cont rolled to stoichiometric, by the sig-
nal from the heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates volt-
age from approximately 1 V in richer conditions to 0 V in leaner con-
ditions.
Under normal conditions the heated ox ygen sensor 2 is not used for
engine control operation.
Heated Oxygen Sensor 2 HeaterINFOID:0000000012431290
SYSTEM DESCRIPTION
The ECM performs ON/OFF control of the heated oxy gen sensor 2 heater corresponding to the engine speed,
amount of intake air and engine coolant temperature.
OPERATION
Ignition Coil With Power TransistorINFOID:0000000012431291
The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns
ON and OFF the ignition coil primary circuit. This ON/O FF operation induces the proper high voltage in the coil
secondary circuit.
Intake Air Temperature SensorINFOID:0000000012431292
The intake air temperature sensor is built-into mass air flow sensor
(1). The sensor detects intake air temperature and transmits a signal
to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to
the change in temperature. Electrical resistance of the thermistor
decreases in response to the temperature rise.
