Description

EBS014Y0

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 Mode

EBS014Y1

Specification data are reference values.

*: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.

ECM Terminals and Reference Value

EBS014Y2

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.

NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.

WITH CONSULT-II

1.

Turn ignition switch ON.

2.

Select “DATA MONITOR” mode with CONSULT-II.

3.

Wait at least 5 seconds.
