DTC P2135 APP SENSOR

DTC P2135 APP SENSORPFP:18002
DescriptionEBS0124O
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 ModeEBS0124P
Specification data are reference values.
*: These signals are converted by ECM internally. Thus, these differ from ECM terminals voltage.
On Board Diagnosis LogicEBS0124R
The MI will not light up for this self-diagnosis.
NOTE:

If DTC P2135 is displayed with DTC P0642 or P0643, first perform trouble diagnosis for DTC P0642
or P0643. Refer to EC-1575, "
DTC P0642, P0643 SENSOR POWER SUPPLY" .

If DTC P2135 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652
or P0653. Refer to EC-1579, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
DTC Confirmation ProcedureEBS0124S

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.

DTC P2146, P2149 FUEL INJECTOR POWER SUPPLYPFP:16600
Component DescriptionEBS0124X
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the cylinder. The
amount of fuel injected depends upon the injection pulse duration.
Pulse duration is the length of time the fuel injector remains open.
The ECM controls the injection pulse duration based on engine fuel
needs.
