Fuel Pressure Regulator CheckNEEC00261. Stop engine and disconnect fuel pressure regulator vacuum
hose from intake manifold.
2. Plug intake manifold with a rubber cap.
3. Connect variable vacuum source to fuel pressure regulator.
4. Start engine and read indication of fuel pressure gauge as
vacuum is changed.
Fuel pressure should decrease as vacuum increases. If results
are unsatisfactory, replace fuel pressure regulator.

REMOVAL AND INSTALLATIONNEEC00271. Release fuel pressure to zero.
2. Remove injector tube assembly with injectors from intake
manifold.
3. Remove injectors from injector tube assembly.
+Push injector tail piece.
+Do not pull on the connector.
4. Install injector to fuel tube assembly.
a. Clean exterior of injector tail piece.
b. Use new O-rings.
Always replace O-rings with new ones.
Lubricate O-rings with a smear of engine oil.
5. Install injectors with fuel tube assembly to intake manifold.
Tighten in numerical order shown in the figure.
a. First, tighten all bolts to 9.3 to 10.8 N´m (0.95 to 1.1 kg-m, 6.9
to 8.0 ft-lb).
b. Then, tighten all bolts to 21 to 26 N´m (2.1 to 2.7 kg-m, 15 to
20 ft-lb).
6. Install fuel hoses to fuel tube assembly.
7. Reinstall any parts removed in reverse order of removal.
CAUTION:
After properly connecting injectors to fuel tube assembly,
check connections for fuel leakage.

Fast Idle Cam (FIC)
COMPONENT DESCRIPTIONNEEC0502The FIC is installed on the throttle body to maintain adequate
engine speed while the engine is cold. It is operated by a volumet-
ric change in wax located inside the thermo-element. The thermo-
element is operated by engine coolant temperature.

Component DescriptionNEEC0213The crankshaft position sensor (OBD) is located on the transaxle
housing facing the gear teeth (cogs) of the flywheel or drive plate.
It detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet, core and coil.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
This sensor is not directly used to control the engine system. It is
used only for the on board diagnosis.
ECM Terminals and Reference ValueNEEC0214Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

+The refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
6. Check oil level as follows.
a. Start engine and check area around drain plug and oil filter
for oil leakage.
b. Run engine for a few minutes, then turn it off. After more than
10 minutes, check oil level.

REMOVAL
1. Place a pan to catch the oil under the lower part of drain hose
outlet before removing filter body.
2. Using a hexagonal socket wrench [plane-to-plane width: 24
mm (0.94 in)], loosen the filter body approximately four turns.
3. Remove the filter body, then remove the oil filter element.
4. Remove the O-ring from the filter body.
+Push the O-ring in one direction, lift the slack part using
fingers, and remove the O-ring from the filter body.
CAUTION:
Do not use wires or flat-bladed screwdrivers etc. as they
may cause damage to the filter body.
INSTALLATION
1. Completely remove all foreign objects adhering to the inside
of the filter body or O-ring mounting area (filter body side and
bracket side).
2. Install the oil filter element and O-ring to the filter body.
+Push the oil filter element into the filter body completely.
3. Install the filter body to the oil filter bracket.
:20-25Nzm (2.0 - 2.6 kg-m, 15 - 18 ft-lb)
4. After warming up the engine, check for engine oil leakage
and oil level.
CAUTION:
Completely wipe clean any engine oil remaining on the fil-
ter body or vehicle.
Changing Engine Coolant
To avoid the danger of being scalded, never change the
coolant when the engine is hot.
Ð DRAINING ENGINE COOLANT Ð
1. Set air conditioning system as follows to prevent coolant from
remaining in the system.
a. Turn ignition switch ON and set temperature controller to
maximum hot position.
b. Wait 10 seconds before turning ignition switch OFF.
2. Open radiator drain plug at the bottom of radiator and
remove radiator cap to drain coolant.
