DTC P1180 FUEL TEMPERATURE SENSOR
DTC P1180 FUEL TEMPERATURE SENSOR
PFP: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 to EC-1498, "

DTC P1217 OVERHEAT (COOLING SYSTEM)
PFP:00021
DescriptionEBS004QR
SYSTEM DESCRIPTION
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air condi-
tioner ON signal. The control system has 3-step control [HIGH/LOW/OFF].
OPERATION
CONSULT-II Reference Value in Data Monitor ModeEBS004QS
Specification data are reference values.
ECM Terminals and Reference ValueEBS004QT
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 LogicEBS004QU
This diagnosis continuously monitors the engine coolant temperature.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
