I'm trying to help my brother-in-law diagnose his 2000 4WD 3.0 liter Ranger with flex fuel. I pulled out 4 codes the other day, one of which was P0176 Flex Fuel Sensor.
Does anyone know the procedure for checking this sensor and associated wiring? What resistances or voltages should I be getting when I check them. Any diagrams related to the checking procedure are greatly appreciated.
Also, if it is found that the sensor is bad, does anyone know where to get a cheap one? It appears the sensor is between $600-700. I found a company that lets you "bypass" the sensor and fool the computer Flex Fuel Sensor Replicator for a Ford
Has anyone used this product? Has anyone made their own? I don't think it would be too hard.
It seems like unplugging the sensor will just make the truck randomly shut off which is not good.
Thanks for the help!
