THROTTLE POSITION SENSOR ADJUSTMENT
NOTE
When using the scan tool, service item 26
and observe the ON/OFF changes posi-
tion switch instead of performing
If the scan
tool is not available, follow the steps bellow.
1.Disconnect the connector the throttle position sensor.
2.Connect an ohmmeter between terminal 3 (closed
position switch) and 4 (sensor ground) by using jum per
wires.

3.Insert a feeler gauge with a thickness of 0.45 mm
in.) between the fixed SAS and the throttle lever.
4. Loosen the throttle position sensor mounting bol t; then
turn the throttle position sensor body fully counter clock-
wise.
5.In this condition, check for continuity between terminals
3 and 4.
6. Slowly turn the throttle position sensor clockwi se until
the point at which continuity between terminals 3 a nd
4 changes to non-continuity is found.
Tighten the throttle position sensor installation b olt at
that position.
7. Connect the connector of the throttle position s ensor.
8.Connect the scan tool to the data link connector

Connect a hand vacuum pump to the nipple.
Connect a battery to the solenoid valve and apply a vacu-
um to check air-tightness.

INSTALLATION SERVICE POINTS
INJECTORS INSTALLATION
(1) Apply a small amount of clean engine oil to the O-ring.
Caution
Donot let the engine oil get into the fuel rail.
(2) While
injector to the left and right, install it
to the fuel rail.
(3) Check to be sure that the injector turns smooth ly.
If it does not turn smoothly, the O-ring may be tra pped,
remove the injector and then, re-insert it into the fuel rail
and check once again.
FUEL PRESSURE REGULATOR
(1) Apply a small amount of clean engine oil to a n ew
and insert it to the fuel rail carefully.
Do not let the engine oil get into rail.
(2) If the fuel pressure regulator does
the O-ring may be folded.Then, remove regulator
to check the O-ring for damage.
(3) Tighten the regulator to the specified
Tightening torque: 8.8 Nm ‘(6.5
HIGH-PRESSURE FUEL
When connecting the high-pressure fuel hose to the fuel rail,
apply a small amount of clean engine oil to the hose union,
and then insert, being careful not
damage ‘the O-ring.,
Do not let the engine into
