DTC P0181-P0183: Engine Fuel Temperature (Eft) Sensor: Description

Engine Fuel Temperature (EFT) sensor is located on the fuel rail and informs ECM when fuel rail temperature is high. Because of fuel vaporization and possible bubbles in the fuel rail, ECM will increase injector pulse width during hot engine restarts to clear bubbles. During engine operation fuel circulation keeps fuel rail temperature low. There is no default strategy for the EFT sensor. An EFT sensor fault may result in a hot engine restart problem. A fault is indicated by illumination of the MIL.
