P0176 Flexible Fuel Sensor.
The sensor input signal to PCM is continuously moniterod. The test fails when the sensor exceeds or falls before a max. or min. calibrated range.
FF = flexible flue
Causes
-Open or short in FF sensor VPWR circuit
-open in battery ground to FF sensor circuit
-open in FF sensor signa; circuit
-short to ground in FF signal circuit
-fuel contamination
-short to VPWR in FF sensor battery ground circuit
-short to VPWR in FF sensor signal circuit
-fuel seperation
-damaged FF sensor
-damaged PCM
If it were me I would find out where the hell the sensor is and clean out the contacts and make sure it is plugged in snugly.
