FUEL SYSTEM (DFI) 3-65
Water Temperature Sensor (Service Code 14)
•
Turn the ignition switch OFF.
If the output voltage is out of the specified, check the ECU
for its ground, and power supply (see ECU Power Supply
Inspection). If the ground and power supply are good,
replace the ECU (see ECU section).
If the output voltage is far out of the specified (e.g. when
the wiring is open, the voltage is about 5V), check the
wiring (see wiring diagram in this section).
If the wiring is good, check the water temperature sensor
resistance.
•
Remove the needle adapter set, and apply silicone
sealant to the seals of the ECU connector for waterproof-
ing.
