DTC P0182, P0183 FUEL PUMP TEMPERATURE SENSORPFP:16700
DescriptionEBS01195
Fuel pump temperature sensor is built in the fuel pump. The sensor detects the fuel temperature in the fuel
pump and calibrates the fuel injection amount change by fuel temperature.
CONSULT-II Reference Value in Data Monitor ModeEBS01196
Specification data are reference values.
ECM Terminals and Reference ValueEBS01197
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 LogicEBS01198
DTC Confirmation ProcedureEBS01199
NOTE:
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.
3. Wait at least 5 seconds.
4. If 1st trip DTC is detected, go to EC-995, "
Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

DTC P0192, P0193 FRP SENSORPFP:16638
DescriptionEBS0119D
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 ModeEBS0119E
Specification data are reference values.
ECM Terminals and Reference ValueEBS0119F
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.
