CIRCUIT DESCRIPTION
To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a three-way cata-
lytic converter is used, but for the most efficient use of the three-way catalytic converter, the air-fuel ratio
must be precisely controlled so that it is always close to the stoichiometric air-fuel ratio.
The heated oxygen sensor has the characteristic which its output voltage changes suddenly in the vicinity
of the stoichiometric air-fuel ratio. This characteristic is used to detect the oxygen concentration in the ex-
haust gas and provide the ECM with feedback to control the air-fuel ratio.
When the air-fuel ratio becomes LEAN, the oxygen concentration in the exhaust increases and the heated
oxygen sensor informs the ECM of the LEAN condition (low voltage, i.e. less than 0.45 V).
When the air-fuel ratio is RICHER than the stoichiometric air-fuel ratio, the oxygen concentration in the ex-
haust gas is reduced and the heated oxygen sensor informs the ECM of the RICH condition (high voltage,
i.e. more than 0.45 V). The ECM judges by the voltage output from the heated oxygen sensor whether the
air-fuel ratio is RICH or LEAN and controls the injection time accordingly. However, if malfunction of the
heated oxygen sensor causes output of abnormal voltage, this disables the ECM for performing an accurate
air-fuel ratio control. The heated oxygen sensors include a heater which heats the zirconia element. The
heater is controlled by the ECM. When the intake air volume is low (the temperature of the exhaust gas is
low) current flows to the heater to heat the sensor for accurate oxygen concentration detection.
HINT:
The ECM provides a pulse width modulated control circuit to adjust current through the heater. The heated
oxygen sensor heater circuit uses a relay on the B+ side of the circuit.

(b) Check the valve seating position.
Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:
If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.
If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
Check that the seat contact is in the middle of the
valve face with the following width:
1.0 - 1.4 mm (0.039 - 0.055 in.)
If not, correct the valve seats as follows:
If the seating is too high on the valve face, use 30°
and 45° cutters to correct the seat.
If the seating is too low on the valve face, use 60°
and 45° cutters to correct the seat.
(d) Hand-lap the valve and valve seat with an abrasive com-
pound.
(e) After hand-lapping, clean the valve and valve seat.
12. INSPECT VALVE SPRINGS

8. INSTALL CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being removed.
Otherwise, excessive pressure is put on the cylinder head
journal thrust, causing a burr on the journal and damage on
the camshaft. To avoid this, follow the steps below.
(a) Set the crankshaft pulley position.
Turn the crankshaft pulley clockwise or counterclockwise,
and put the timing mark of the crankshaft pulley in line with
the centers of the crankshaft pulley bolt and the idler
pulley bolt.
NOTICE:
Having the crankshaft pulley at the wrong angle can cause
the piston head and the valve head to come into contact
with each other when removing the camshaft, causing
damage on them. So always set the crankshaft pulley at the
correct angle.
(b) Install the RH camshafts.
(1) Apply MP grease to the thrust portion of the intake
and exhaust camshafts.
(2) Place the intake and exhaust camshafts.
(3) Set the timing mark (1 dot mark) of the camshaft
main gear at approx. 10° angle.
(4) Remove any old packing (FIPG) material from the
front bearing cap.
(5) Apply seal packing to the front bearing cap as
shown in the illustration.
Seal packing:
Part No. 08826-00080 or equivalent
Install a nozzle that is cut to a 1.5 mm (0.06
in.) opening.
Parts must be assembled within 5 minutes
the seal packing application. Otherwise the
material must be removed and the packing
have to be reapplied.
Immediately remove nozzle from the tube
and reinstall cap.
NOTICE:
Do not apply seal packing to the front bearing cap grooves.

(12) Move a service bolt of the sub-gear upward by turn-
ing the hexagon shaped port of the exhaust cam-
shaft with a wrench.
(13) Remove the service bolt.
(c) Install the LH camshafts.
(1) Apply MP grease to the thrust portion of the intake
and exhaust camshafts.
(2) Place the intake and exhaust camshafts.
(3) Engage the intake to the exhaust gear by putting
the timing marks (2 dot marks) on each gear.
(4) Remove any old packing (FIPG) material.
(5) Apply seal packing to the front bearing cap.
Seal packing:
Part No. 08826-00080 or equivalent
Install a nozzle that is cut to a 1.5 mm (0.06
in.) opening.
Parts must be assembled within 5 minutes

material must be removed and the packing
have to be reapplied.
Immediately remove nozzle from the tube
and reinstall cap.
NOTICE:
Do not apply seal packing to the front bearing cap grooves.
(6) Install the front bearing cap.
HINT:
Installing the front bearing cap will determine the thrust portion
of the camshaft.
(7) Install the other bearing cap in the sequence shown
with the arrow mark facing forward.
HINT:
Align the arrow marks at the front and rear of the cylinder head
with the mark on the bearing cap.
