DTC P0192, P0193 FRP SENSOR
DTC P0192, P0193 FRP SENSOR
PFP:16638
DescriptionEBS01KEZ
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 ModeEBS01KF0
Specification data are reference values.
ECM Terminals and Reference ValueEBS01KF1
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.
On Board Diagnosis LogicEBS01KF2
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 the trouble diagnosis for
DTC P0652 or P0653. Refer toEC-227, "
DTC P0652, P0653 SENSOR POWER SUPPLY".
