Accelerator Pedal Position (APP) Sensor
Assembly On-Vehicle Inspection
1) Check that APP sensor assembly has been mounted
to vehicle body properly (no pinched floor carpet,
etc.).
If mounting is not properly, reinstall APP sensor
assembly properly referring to "Accelerator Pedal
Position (APP) Sensor Assembly Removal and
Installation".
2) Connect scan tool to DLC with ignition switch turned
OFF.
3) Turn ON ignition switch and select "Data List" mode
on scan tool.
4) Check that accelerator pedal position sensor voltage
varies as the following graph.
If sensor voltage is out of specified value or does not
vary linearly as the following graph, check APP
sensor assembly referring to "Accelerator Pedal
Position (APP) Sensor Assembly Inspection".

Assembly Removal and Installation
CAUTION
!
• Do not expose APP sensor assembly to
excessive shock like a dropping it. If APP
sensor assembly has been exposed to
excessive shock, it should be replaced.
• Be careful not to expose sensor section of
APP sensor assembly to water.

NOTE
After replacing APP sensor assembly,
perform calibration of throttle valve referring
to "Electric Throttle Body System
Calibration".
Removal
1) Disconnect negative cable at battery.
2) Disconnect connector from APP sensor assembly.
3) Remove APP sensor assembly from its bracket.
Installation
Reverse removal procedure for installation noting the
following.
• Tighten APP sensor assembly upper nut (1) first and
then lower nuts (2) to specified torque.
Tightening torque
APP sensor assembly nut (a): 6 N⋅m (0.6 kgf-m, 4.5
lb-ft)

• Connect connector to APP sensor assembly securely.
Accelerator Pedal Position (APP) Sensor
Assembly Inspection
Check APP sensor (main and sub) output voltage as
following steps.
1) For APP sensor (main), arrange 3 new 1.5 V
batteries (1) in series (check that total voltage is 4.5
– 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.
