REMOVAL SERVICE POINT
AA"DELIVERY PIPE/INJECTOR REMOVAL
Remove the delivery pipe (with the injectors attached to it).
Caution
Care must be taken, when removing the delivery pipe,
not to drop the injector.
INSTALLATION SERVICE POINT
"AAINJECTOR/FUEL PRESSURE REGULATOR
/HIGH-PRESSURE FUEL HOSE INSTALLATION
1. Apply a drop of new engine oil to the O-ring.
Caution
Be sure not to let engine oil enter the delivery pipe.
2. While turning the injector, high-pressure fuel hose and
fuel pressure regulator to the right and left, install the
delivery pipe, while being careful not to damage the O-ring.
After installing, check that the hose turns smoothly.
3. If it does not turn smoothly, the O-ring may be trapped,
remove the injector, high-pressure fuel hose or fuel
pressure regulator and then re-insert it into the delivery
pipe and check once again.
4. Tighten the high-pressure fuel hose and fuel pressure
regulator to the specified torque.
Tightening torque:
5.0±1.0 N·m (High-pressure fuel hose)
8.9±1.9 N·m (Fuel pressure regulator)

INSTALLATION SERVICE POINT
"AATHROTTLE POSITION SENSOR INSTALLATION
1. Set the throttle position sensor on the throttle body as
shown in illustration (1).
2. Turn and set the throttle position sensor to the position
shown in illustration (2), connect a circuit tester across
terminal No. 2 (Throttle position sensor output) and
terminal No. 4 (earth), and measure the output voltage.
Tighten the throttle position sensor with a screw at the
position where the output voltage is at the standard value.
Standard value: 0.535 - 0.735 V

MPI -Throttle Body13A-145
3. After installing the Throttle position sensor, check that
the output voltage is at the standard value. If deviated
from the standard value, loosen the screw, readjust to
the standard position, and then fix. Repeat this step until
the output voltage is at the standard value.
4. Connect a circuit tester across terminal No. 1 (Throttle
position sensor power) and terminal No. 2 (Throttle
position sensor output). Check that the resistance
changes smoothly when the throttle valve is slowly moved
to the fully opened position.Throttle position
