Fuel+Temp+Sensor

toc The **Fuel Temp Sensor** is a temperature sensor mounted to the fuel rail on the Z32. It reads the fuel temperature to determine whether or not to raise the fuel pressure using the PRVR Solenoid



=Function= The **Fuel Temp Sensor** employs a thermistor to return a variable voltage to the ECU which is translated into a temperature reading by the ECU. The ECU uses the temperature value to determine whether or not to activate the PRVR Solenoid when starting the engine.

It uses the same voltage - temperature conversion as the coolant temp sensor. In fact, aside from its shape and form factor, it is functionally identical to the coolant temp sensor.

=Location= The Fuel Temp Sensor is located on the driver's side fuel rail, near the Cylinder 2 fuel injector. Its mounting position in the fuel rail is sealed. That is, it can be removed without any fuel escaping.
