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.
