c. Press-fit the rear oil seal using a suitable drift (A) with outer
diameter 113 mm (4.45 in) and inner diameter 90 mm (3.54 in).
• Press-fit to the specified dimensions as shown.
CAUTION:
• Do not touch the grease applied to the oil seal lip.
• Be careful not to damage the rear oil seal mounting partof oil pan (upper) and cylinder block or the crankshaft.
• Press-fit straight and check that oil seal does not curl or tilt.
d. After press-fitting the rear oil seal, completely wipe off any liquid gasket protruding to rear end surface side.
3. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, includi ng 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 leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak- age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage 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 is no leakage 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.

INSPECTION AFTER REMOVAL
Oil Filter
• Check that there is no foreign material on the oil filter (1) and check it for clogging.
• Check the oil filter for damage.
• If there is some damage, replace the oil filter, the plug, and the washer as a set.
CAUTION:
Do not reuse the washer.
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour- nals of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a differe nt diameter from the other
four locations.
2. Set a suitable tool vertically to No. 3 journal.
3. Turn camshaft to one direction, and measure the camshaft runout using suitable tool. (Total indicator reading)

< SYSTEM DESCRIPTION >[HR16DE]
SYSTEM
*1: M/T models
*2: CVT models
*3: ECM determines the start signal status
by the signals of engine speed and battery voltage.
*4: This signal is sent to the ECM through CAN communication line.
SYSTEM DESCRIPTION
Firing order: 1 - 3 - 4 - 2
The ignition timing is controlled by the ECM to maintain the best air-fuel ratio for every running condition of the
engine. The ignition timing data is stored in the ECM.
The ECM receives information such as the injection pulse width and camshaft position sensor signal. Comput-
ing this information, ignition signals are transmitted to the power transistor.
During the following conditions, the ignition timing is re vised by the ECM according to the other data stored in
the ECM.
• At starting
• During warm-up
• At idle
• At low battery voltage
• During acceleration
The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed
within the anti-knocking zone, if recommended fuel is used under dry conditions. The retard system does not
operate under normal driving conditions. If engine knocking occurs, the \
knock sensor monitors the condition.
The signal is transmitted to the ECM. The ECM retards the ignition timing to eliminate the knocking condition.
