Tests DB: Engine Fuel Temperature (EFT) Sensor




NOTE
This Pinpoint Test is intended to diagnose the following:
- Engine Fuel Temperature (EFT) Sensor
- Harness Circuits: EFT and SIG RTN
- Powertrain Control Module (PCM)

EFT Voltage And Resistance Chart:






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.

NOTE: The Engine Fuel Temperature (EFT) sensor will operate within the range of -4O°C to 135°C (-40°F to 275°F)
