DTC P0222, P0223 APP SENSOR
DTC P0222, P0223 APP SENSOR
PFP:18002
DescriptionEBS01KFS
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensors detect the accelera-
tor pedal position and sends a signal to the ECM. The ECM uses the
signal to determine the amount of fuel to be injected.
CONSULT-II Reference Value in Data Monitor ModeEBS01KFT
Specification data are reference values.
*: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
ECM Terminals and Reference ValueEBS01KFU
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
