DTC P2135 APP SENSORPFP:18002
DescriptionEBS01KKT
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 ModeEBS01KKU
Specification data are reference values.
*: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
ECM Terminals and Reference ValueEBS01KKV
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.
