Econoline E350 1 Ton V8-5.4L CNG VIN M (1999)
Fuel Temperature Sensor: Description and Operation
Engine Fuel Temperature Sensor
The engine fuel temperature sensor is located on the fuel injection supply manifold, and is used to provide a signal to the powertrain control module
that indicates the temperature of the fuel in the fuel injection supply manifold.
Tank Temperature Sensor
The tank temperature sensor:
-
changes resistance in response to the temperature of the fuel in the fuel tank; as the surrounding temperature increases, the resistance decreases
(the voltage signal also decreases).
-
provides a signal to the NGV module that indicates the temperature of the fuel.
-
is mounted in the high-pressure fuel line downstream of the coalescer filter.
