Standard Ignition Flex Fuel Sensor P/N:FFS3
Standard Ignition FFS2 flex fuel sensor for the 1999-2003 Ford Ranger V6 3.0L and other vehicles reports the fuel's ethanol content to the engine computer.
A failing flex fuel sensor can show up as a check engine light, rough running or poor fuel economy. Other faults produce these symptoms too, so start with a look at the connector and wiring with the engine off, checking for corrosion, bent terminals or damage. A shop can test the sensor itself.
It fits the 1999-2003 Ford Ranger V6 3.0L and the 2001 Ford Explorer V6 4.0L. This listing is one sensor, and the 2001 Ford Explorer V6 4.0L takes one.
