DTC P0182, P0183 FUEL PUMP TEMPERATURE 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.
Diagnostic ProcedureEBS0119B
1. CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Loosen and retighten ground screws on the body. Refer to EC-1055, "
Ground Inspection" .
OK or NG
OK >> GO TO 2.
NG >> Repair or replace ground connections.

DTC P0192, P0193 FRP SENSOR

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.
On Board Diagnosis LogicEBS0119G
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-1240, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
DTC Confirmation ProcedureEBS0119H
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 E C - 111 3 , "
Diagnostic Proce-
dure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.
