(2) Remove the spark plugs.
(3) Visually check the spark plug.
If the electrode is dry, the spark plug is
functioning properly. If the electrode is damp,
proceed to the next step.
(c) Check the spark plug for any damage to its threads
and insulator. If there is damage, replace the spark
plug.
Recommended spark plug
NOTICE:
Use only the listed spark plug or equivalent to
ensure engine performance and smooth
driveability.
(d) Check the spark plug electrode gap.
Maximum electrode gap for used spark plug:
1.4 mm (0.055 in.)
If the gap is greater than the maximum, replace the
spark plug.
Electrode gap for new spark plug:
1.0 to 1.1 mm (0.039 to 0.043 in.)
(e) Clean the spark plugs.
If the electrode has traces of wet carbon, clean the
electrode with a spark plug cleaner and then dry it.
Standard air pressure:
588 kPa (6 kgf*cm
2, 85 psi)
Standard duration:
20 seconds or less
HINT:
Only use the spark plug cleaner when the electrode
is free of oil. If the electrode has traces of oil, use
gasoline to clean off the oil before using the spark
plug cleaner.
(f) Install the ignition coil assembly and spark plug.

HINT:
• Although the DTC titles say oxygen sensor, these DTCs relate to the Air-Fuel Ratio (A/F) sensor.
• Sensor 1 refers to the sensor mounted in front of the Three-Way Catalytic Converter (TWC) and
located near the engine assembly.
DESCRIPTION
The A/F sensor generates a voltage* that corresponds to the actual air-fuel ratio. This sensor voltage is
used to provide the ECM with feedback so that it can control the air-fuel ratio. The ECM determines the
deviation from the stoichiometric air-fuel ratio level, and regulates the fuel injection time. If the A/F sensor
malfunctions, the ECM is unable to control the air-fuel ratio accurately.
The A/F sensor is the planar type and is integrated with the heater, which heats the solid electrolyte
(zirconia element). This heater is controlled by the ECM. When the intake air volume is low (the exhaust
gas temperature is low), a current flows into the heater to heat the sensor, in order to facilitate accurate
oxygen concentration detection. In addition, the sensor and heater portions are narrower than the
conventional type. The heat generated by the heater is conducted to the solid electrolyte through the
alumina, therefore the sensor activation is accelerated.
A three-way catalytic converter (TWC) is used in order to convert the carbon monoxide (CO), hydro
carbon (HC), and nitrogen oxides (HOx) into less harmful substances. To allow the TWC to function
effectively, it is necessary to keep the air-fuel ratio of the engine near the stoichiometric air-fuel ratio.
*: Value changes inside the ECM. Since the A/F sensor is the current output element, a current is
converted to a voltage inside the ECM. Any measurements taken at the A/F sensor or ECM connectors
will show a constant voltage.

(b) Observe the following precautions when removing
and installing the fuel injectors:
(1) Never reuse an O-ring.
(2) When placing a new O-ring on the injector, do
not damage the O-ring.
(3) Coat a new O-ring with spindle oil or gasoline
before installing it.
NOTICE:
Do not use engine oil, gear oil or brake fluid.
(c) Install the injector to the delivery pipe and the lower
intake manifold as shown in the illustration.
NOTICE:
Before installing the injector, be sure to apply
appropriate lubricant or gasoline to the place
where the delivery pipe or cylinder head
contacts the injector O-rings.
(d) Observe the following precautions when
disconnecting the fuel tube connectors (Quick type
A):
(1) Remove the No. 1 fuel pipe clamp.
(2) Check that there is no dirt or other foreign
objects on the pipe and around the connector
before disconnecting them. Clean them if
necessary.
(3) Disconnect the connector from the pipe by hand.
(4) If the connector and the pipe are stuck, push in
and pull on the connector to release it. Pull the
connector out of the pipe carefully.
(5) Check that there is no dirt or other foreign
objects on the sealing surface of the
disconnected pipe. Clean the surfaces if
necessary.
