DTC P0192, P0193 FRP SENSOR
PFP:16638
Description
EBS014V0
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 Mode
EBS014V1
Specification data are reference values.
ECM Terminals and Reference Value
EBS014V2
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 Logic
EBS014V3
The MI will not light up for these self-diagnoses.

Trouble diagnosis name
DTC detecting condition
Possible cause
P0192
Fuel rail pressure sensor
circuit low input
An excessively low voltage from the sensor is
sent to ECM.
●
Harness or connectors
(The sensor circuit is open or shorted.)
●
Fuel rail pressure sensor
P0193
Fuel rail pressure sensor
circuit high input
An excessively high voltage from the sensor is
sent to ECM.
