DTC P0190 COMMON RAIL FUEL PRESSURE SENSOR
DTC P0190 COMMON RAIL FUEL PRESSURE SENSOR
PFP:16638
DescriptionEBS004RD
The common rail fuel pressure sensor is placed to the common rail. It measures the fuel pressure in the com-
mon rail. The sensor sends voltage signal to the ECM. As the pressure increases, the voltage rises.
The ECM controls the fuel pressure in the common rail by the suction control valve. The ECM uses the signal
from common rail fuel pressure sensor as a feedback signal.
CONSULT-II Reference Value in Data Monitor ModeEBS008YH
Specification data are reference values.
ECM Terminals and Reference ValueEBS008YI
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.
