Po176 code in 2000 ford ranger 3.0l
P0176 - Flexible Fuel (FF) Sensor Circuit Malfunction
"The FF sensor input signal to PCM is continuously monitored. The test fails when the signal falls out of a maximum or minimum calibrated range."
This sometimes requires replacement of the FF sensor which is part of a larger assembly. It is very expensive ($400?). Before throwing any parts at it, I would run some more fuel through it and reset the PCM by disconnecting the negative battery cable for a minute or two.
Here is the complete list of possible causes from Ford:
-Open or short in FF sensor VPWR circuit
-Open in battery ground to FF sensor circuit
-Open in FF sensor signal circuit
-Short to ground in FF sensor signal circuit
-Short to VPWR in FF sensor battery ground circuit
-Short to VPWR in FF sensor signal circuit
-Damaged FF sensor
