DTC P0122, P0123 APP SENSOR

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 P0192, P0193 FRP SENSOR

DTC P0192, P0193 FRP SENSORPFP:16638
DescriptionEBS011ZK
The fuel rail pressure (FRP) sensor is placed to the fuel rail. It measures the fuel pressure in the fuel rail. The
sensor sends voltage signal to the ECM. As the pressure increases, the voltage rises.
The ECM controls the fuel pressure in the fuel rail by the inlet throttling device. The ECM uses the signal from
fuel rail pressure sensor as a feedback signal.
CONSULT-II Reference Value in Data Monitor ModeEBS011ZL
Specification data are reference values.
On Board Diagnosis LogicEBS011ZN
The MI will not light up for these self-diagnoses.
NOTE:

If DTC P0192 or P0193 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for
DTC P0652 or P0653. Refer to EC-1579, "
