3. Tighten nuts in numerical order to the specified torque again.
Air-fuel ratio sensor 1
• Use Tool (A) to install the air-fuel ratio sensor 1 (if removed). CAUTION:
• Handle it carefully and avoid impacts.
• Before installing a new air-fu el ratio sensor 1, clean the
exhaust tube threads using suit able tool and approved anti-
seize lubricant.
• Do not over-tighten the air-fuel ratio sensor 1. Doing so may damage the air-fuel ratio senso r 1, resulting in the MIL com-
ing on.
INSPECTION AFTER INSTALLATION
Inspection
• Start engine and raise engine speed to check for exhaust leaks.

2. Apply a continuous bead of liquid gasket (A) with a tube presser
as shown.
Use Genuine Silicone RTV S ealant or equivalent. Refer
to GI-22, "
Recommended Chemical Products and Sealants"
CAUTION:
• Installation should be done within 5 minutes after apply-
ing liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after
the components are installed to allow the sealant to cure.
3. Tighten bolts in numerical order as shown.
4. Install oil pan drain plug. CAUTION:
• Do not reuse drain plug washer.
• Refer to exploded view installation di rection of drain plug washer. Refer to EM-34
.
5. Refill the engine with engine oil. Refer to LU-8, "
Refilling".
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, including 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, che ck 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.

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.

c. After connecting, check that the connection is secure:
• Visually confirm that the two retainer tabs are connected to theconnector.
• With the fuel feed hose not fix ed to the clamp, pull quick con-
nector (A) hard by hand to check that the quick connector (A)
is not disconnected from the centralized underfloor piping (1)
and that the quick connector (1) is securely connected.
9. Installation of remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Check on Fuel Leaks
1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, check there are no fuel leaks at connection points. Refer to.
NOTE:
Use mirrors for checking points out of clear sight.
2. Start the engine. With engine speed increased, check again that there are no fuel leaks at connection
points.
• Perform procedures for “Throttle Valve Closed Posi tion Learning” after finishing repairs. Refer to EC-
129, "Description".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-130, "
Description".
CAUTION:
Do not touch the engine immediately after stopping, as the engine becomes extremely hot.

TIMING CHAIN
b. Cut liquid gasket by prying the position ( ) as shown, and then
remove the front cover.
12. Remove front oil seal from front cover using a suitable tool. CAUTION:
Be careful not to damage the front cover.
13. Remove chain tensioner (1):
a. Fully push down the chain tensioner lever (A), and then push the plunger (C) into the inside of tensioner.
• The tab (B) is released by fully pushing the lever down. Thenthe plunger can be moved.
b. Pull up the lever to align its hole position with the body hole posi- tion.
• When the lever hole is aligned with the body hole position, theplunger is secured.
• When the protrusion parts of the plunger ratchet and the tab face each other, both hole positions are not aligned. At that
time, correctly engage them and align these hole positions by
slightly moving the plunger.
c. Insert the stopper pin (D) into the body hole through the lever hole, and then secure the lever at the upper position.
NOTE:
A hexagonal wrench of 2.5 mm (0.098 in) is used as a stopper pin (D).
d. Remove chain tensioner.
14. Remove the timing chain tension guide (2) and the timing chain slack guide (1).
15. Remove the timing chain (2). • Pull the timing chain slack toward the camshaft sprocket
(EXH) (1), and then remove the timing chain and start the
removal from camshaft sprocket (EXH) side.
CAUTION:
Do not rotate crankshaft or camshaft while timing chain is
removed. It causes interferen ce between valve and piston.
16. Remove the crankshaft sprocket and the oil pump drive:
