2) For accelerator pedal position (APP) sensor (sub),
arrange 3 new 1.5 V batteries (1) in series (check
that total voltage is 4.7 – 5.0 V) and connect its
positive terminal to "Vin 2" terminal (2) and negative
terminal to "Ground 2" terminal (3) of sensor. Then
using voltmeter connect positive terminal to "Volt 2"
terminal (4) of sensor and negative terminal to
battery.

3) Measure output voltage variation while accelerator
pedal is no depressed and fully depressed as
following specification.
If sensor voltage is out of specified value or does not
vary linearly as the following graph, replace accelerator
pedal position assembly.
Accelerator pedal position (APP) sensor output
voltage
Accelerator pedal position (APP) sensor (main)
output voltage [A]: 0.82 – 3.50 V, varying according
to depressed extent of accelerator pedal
Accelerator pedal position (APP) sensor (Sub)
output voltage [B]: 0.44 – 1.74 V, varying according
to depressed extent of accelerator pedal
[C]
3.50 - 4.27 V
1.74 - 2.17 V
0.65 - 0.82 V
0.30 - 0.44 V

Engine Coolant Temperature (ECT) Sensor
Removal and Installation
Removal
1) Disconnect negative cable at battery.
2) Drain cooling system referring to "Cooling System
Description: For Diesel Engine Model in Section 1F".
3) Disconnect ECT sensor connector (1).
4) Remove ECT sensor (1) from thermostat assembly
by removing clip (2).
Installation
Reverse removal procedure for installation noting the
following.
• Check ECT sensor O-ring for damage.
If malfunction is found, replace ECT sensor.
• Refill cooling system referring to "Cooling System
Refilling: For Diesel Engine Model in Section 1F".
• Check cooling system leakage referring to "Engine
Cooling System Inspection and Cleaning: For Diesel
Engine Model in Section 1F".
