ACCELERATOR PEDAL POSITION SENSOR

1.

Reconnect all harness connectors disconnected.

2.

Turn ignition switch ON.

3.

Check voltage between ECM terminals 83 (APP sensor 1 sig-
nal), 91 (APP sensor 2 signal) and body ground under the fol-
lowing conditions.

4.

If NG, replace accelerator pedal assembly.

Description

EBS014Y9

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

EBS014YA

Specification data are reference values.

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

ECM Terminals and Reference Value

EBS014YB

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.
