Pinpoint Tests DA: Fuel Rail Temperature (Frt) Sensor: Introduction: Tables
WARNING: This page is about a different car, the 2004 Ford Pickup Heritage. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The fuel rail temperature sensor will operate within the range of -40 °C to 150 °C (-40°F to 302 °F).
Table and Graph voltage values are calculated for VREF = 5.0 volts. These values may vary up to 15% due to sensor and VREF variations.
