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, "

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.
