Electric Throttle Body System Calibration

NOTE
If working the service described under the
"Precautions of Electric Throttle Body
System Calibration in Section 1A" perform
following steps for electric throttle body
system calibration.
1) If electric throttle body assembly and/or APP sensor
assembly are replaced, perform following steps.
a) Disconnect negative cable at battery for 20
seconds or more for the purpose of clearing
calibration data of closed throttle position from
memory in ECM.
b) Connect negative cable to battery.
2) Keep ignition switch at ON position for 5 seconds or
more without running engine.

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 "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 APP 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 "APP Sensor Assembly
Inspection".

APP Sensor 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 nut (2) to specified torque.
Tightening torque
APP sensor assembly nut (a): 5.5 N·m (0.55 kgf-m,
4.0 lb-ft)
