DB: Engine Fuel Temperature (EFT) Sensor Introduction

DB: Pinpoint Tests See: DB: Engine Fuel Temperature (EFT) Sensor - Pinpoint Test

Note

This Pinpoint Test is intended to diagnose the following:

• Engine Fuel Temperature (EFT) Sensor (9F951)
• Harness Circuits: EFT and SIG RTN
• Powertrain Control Module (PCM) (12A650)

Tables and Graphs

Note: The engine fuel temperature (EFT) sensor will operate within the range of -40°C to 135°C (-40°F to 275°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.
