DTC P1180 FUEL TEMPERATURE SENSORPFP:16700
DescriptionEBS004T2
Fuel temperature sensor is built in the fuel supply pump. The sensor detects the fuel temperature in the fuel
supply pump and calibrates the fuel injection amount change by fuel temperature.
CONSULT-II Reference Value in Data Monitor ModeEBS004T3
Remarks: Specification data are reference values.
ECM Terminals and Reference ValueEBS004T4
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 LogicEBS004T5
DTC Confirmation ProcedureEBS004T6
WITH CONSULT-II
1. Turn ignition switch “ON” and wait at least 2 seconds.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and run it for at least 2 seconds at idle speed.
(If engine does not run, turn ignition switch to “START” for at
least 2 seconds.)
4. If DTC is detected, go toEC-753, "
Diagnostic Procedure".

gram.
3. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check harness for open or short to between ECM and fuel temperature sensor.
>> Repair open circuit or short to ground or short to power in harness or connectors.

DTC P1233 - P1234 SUCTION CONTROL VALVE
DTC P1233 - P1234 SUCTION CONTROL VALVE
PFP:16700
DescriptionEBS008XG
To control the amount of the fuel inhalation of the fuel supply pump, a suction control valve is built into the fuel
supply pump. When the amount of the fuel inhalation of fuel supply pump increases, the fuel supply pump
raises the fuel exhalation pressure. As a result, the fuel injection pressure is raised. When the load of the
engine increases, the ECM sends a signal to the suction control valve to raise the injection pressure.

Remarks: Specification data are reference values.
ECM Terminals and Reference ValueEBS008XI
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.
