Electric Throttle Body System CalibrationS7RS0B1306004
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 InspectionS7RS0B1306005
1) Check that APP sensor a ssembly has been mounted
to vehicle body properly (no pinched floor carpet,
etc.).

assembly properly refe rring 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 fo llowing graph, check APP
sensor assembly referring to “APP Sensor Assembly
Inspection”.
