DTC P1510 ACCELERATOR PEDAL RELEASED POSITION SWITCHPFP:18002
DescriptionEBS0096V
The accelerator work unit is installed on the upper end of the accelerator pedal assembly. The accelerator
pedal position sensor 1, 2 and accelerator pedal released position switch are built into the accelerator work
unit. The sensor detects the accelerator pedal position and sends a signal to the ECM. The ECM uses the sig-
nal to determine the amount of fuel to be injected.
The accelerator pedal released position switch detects accelerator pedal released position signal and sends
this signal to the ECM. The ECM will then determine engine idle conditions. This signal is also used for diag-
nosing the accelerator pedal position sensor.
CONSULT-II Reference Value in Data Monitor ModeEBS0096W
Specification data are reference values.
*: Accelerator pedal position sensor 2 signal is converted by ECM internally. Thus, it differ from ECM terminals voltage.
ECM Terminals and Reference ValueEBS0096X
Specification 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.

GLOW CONTROL SYSTEM
GLOW CONTROL SYSTEM
PFP:25230
DescriptionEBS0035J
SYSTEM DESCRIPTION
When engine coolant temperature is more than approximately 80°C (176°F), the glow relay turns off.
When coolant temperature is lower than approximately 80°C (176°F):
●Ignition switch ON
After ignition switch has turned to ON, the glow relay turns ON for a certain period of time in relation to
engine coolant temperature, allowing current to flow through glow plug.
●Cranking
The glow relay turns ON, allowing current to flow through glow plug.
●Starting
After engine has started, current continues to flow through glow plug (after-glow mode) for a certain period
in relation to engine coolant temperature.
The glow indicator lamp turns ON for a certain period of time in relation to engine coolant temperature at the
time glow relay is turned ON.
COMPONENT DESCRIPTION
Glow Plug
The glow plug is provided with a ceramic heating element to obtain a
high-temperature resistance. It glows in response to a signal sent
from the ECM, allowing current to flow through the glow plug via the
glow relay.
ECM Terminals and Reference ValueEBS0035K
Specification 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.

WARNING:
Be sure to read “General Precautions” when working on fuel system. Refer to FL-3, "
General Precau-
tions" .
1. Release fuel pressure from fuel line. Refer to EC-775, "
FUEL
PRESSURE RELEASE" [QR20DE (WITH EURO-OBD)], EC-
11 3 9 , "FUEL PRESSURE RELEASE" [QR20DE (WITHOUT
EURO-OBD)],EC-42, "
FUEL PRESSURE RELEASE"
[QR25DE (WITH EURO-OBD)] or EC-452, "FUEL PRESSURE
RELEASE" [QR25DE (WITHOUT EURO-OBD)].
2. Open fuel filer lid.
3. Open the filler cap and release the pressure inside the fuel tank.
4. Check fuel level on level place. If gauge indicates more than the
level shown in figure (full or almost full), drain fuel from fuel tank
until gauge indicates level shown in figure or below.
In case of fuel pump does not operate, take following procedure.
a. Insert fuel tube of less than 25 mm (0.98 in) in diameter into fuel
filler tube through fuel filler opening to draw fuel from fuel filler
tube.
b. Disconnect fuel filler hose from fuel filler tube.
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel
from fuel tank.
●As a guide, fuel level becomes the position shown in figure or
below when approximately 15 liter (13-1/4 lmp qt) of fuel are drained from fuel tank.
NOTE:
Adjusting fuel level is to prevent fuel from spilling, when fuel level sensor unit, fuel filter and fuel pump
assembly is removed.

ASSEMBLY
Install in the reverse order of removal paying attention to the following.
●Install the fuel filter and fuel pump with the tabs aligned, Make sure a click sound of secure engagement is
heard.
●Securely connect the harness connector of the fuel pump.
●Install the pressure regulator O-ring as follows.
CAUTION:
●When replacing, always use a new O-ring.
●Handle it with bare hands. (Do not use gloves.)
●Visually check the O-ring, mounting parts and mating parts for foreign materials and flaws.
●Before installing, apply new engine oil.
