Description
EBS0154Z
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The ECM uses the signal to
determine the amount of fuel to be injected.
CONSULT-II Reference Value in Data Monitor Mode
EBS01550
Specification data are reference values.
*: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
ECM Terminals and Reference Value
EBS01551
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.

DTC Confirmation Procedure
EBS01553
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.
4.
If DTC is detected, go to
