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".

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.

DTC P1217 OVERHEAT (COOLING SYSTEM)
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in theMA-27,
"Changing Engine Coolant". Also, replace the engine oil.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer toMA-19, "
Engine Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS004QV
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WAR NIN G:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go toEC-764,
"Diagnostic Procedure".
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go toEC-764,
"Diagnostic Procedure".
3. Turn ignition switch “ON”.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II and make sure that cooling fans operate when touching
“HIGH” or “LOW”.
If NG, go toEC-764, "
Diagnostic Procedure".
