Instantaneous Fuel Economy
The Instantaneous Fuel Economy is calculated from the fuel usage and the distance travelled information from the PCM. The vehicle fuel usage information is transmitted via class 2 to the DIC and the distance travelled is based on the 4 Kppm vehicle speed signal from the PCM.
Instantaneous Fuel Economy (IFE) is capable of displaying values from 0 to 99 in whole number increments. The minimum displayed data value for the IFE is 0 MPG (English) and 99 L/100 km (Metric).
Display appears as:
- INST FUEL ECON: ## MPG (English).
- INST FUEL ECON: ## L/100 km (Metric).
Values for the Instantaneous Fuel Economy vary in low speed conditions. If the vehicle speed is less than 1.2 mph, the IFE value will display 0 MPG.
