Nissan Note [1734/1872] Dtc p0180 fuel pump temperature sensor
EC-1734
[K9K]
DTC P0180 FUEL PUMP TEMPERATURE SENSOR
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.
Diagnostic Procedure
