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.

DTC P1216 EDU
DTC P1216 EDU
PFP:22710
DescriptionEBS008X9
The ECM sends the fuel injection signal to EDU (Electronic Drive Unit). Then the EDU sends ON signals to
fuel injectors to operate them.
The EDU monitors injector ground circuit and sends the feed back signal to the ECM.
ECM Terminals and Reference ValueEBS008XB
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.

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".
