Accelerator Pedal Position (APP) Sensor
Assembly Inspection
Check accelerator pedal position (APP) sensor (main
and sub) output voltage as following steps.
1) For accelerator pedal position (APP) sensor (main),
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 1" terminal (2) and negative
terminal to "Ground 1" terminal (3) of sensor. Then
using voltmeter, connect positive terminal to "Vout 1"
terminal (4) of sensor and negative terminal to
battery.
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 "Vout 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 (APP) sensor assembly.

Engine Coolant Temperature (ECT) Sensor
Removal and Installation
Removal
1) Disconnect negative cable at battery.
2) Drain coolant referring to "Cooling System Draining:
in Section 1F".
WARNING
!
To avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot.
Scalding fluid and steam can be blown out
under pressure if cap is taken off too soon.
3) Disconnect connector from ECT sensor (1).
