Accelerator Pedal Position (APP) Sensor
Assembly On-Vehicle Inspection
1) Check that accelerator pedal position (APP) sensor
assembly has been mounted to vehicle body
properly (no pinched floor carpet, etc).
If mounting is not properly, reinstall accelerator pedal
position (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
accelerator pedal position (APP) sensor assembly
referring to "Accelerator Pedal Position (APP)
Sensor Assembly Inspection: ".

Assembly Removal and Installation
CAUTION
!
• Do not expose accelerator pedal position
(APP) sensor assembly to excessive shock
like a dropping it. If accelerator pedal
position (APP) sensor assembly has been
exposed to excessive shock, it should be
replaced.
• Be careful not to expose sensor section of
accelerator pedal position (APP) sensor
assembly to water.
NOTE
After replacing accelerator pedal position
(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 accelerator pedal
position (APP) sensor assembly.
3) Remove accelerator pedal position (APP) sensor
assembly from its bracket.
Installation
