Hi Guys,
I am looking for help with a flex fuel sensor issue. I enabled [flex fuel] and my flex [fuel sensor] in my E67 controller for my LSA engine for the first time. The car has 92 octane gasoline in the tank. With the key on, engine off, the scanner shows [Ethanol Fuel % (SAE)] at 100% and [Fuel Composition Sensor] at 179Hz. The car will flood if I try to start it with the Ethanol Fuel at 100%.
I understand the Conti sensor outputs >170Hz if the fuel is contaminated... however I am unclear how the fuel can be contaminated as I have less than 50 miles on the car (new car build). I confirmed the sensor is pinned correctly (Pin1-Vcc; Pin2-Grd; Pin3-Vout).
I'd like input if you have experience with the sensor outputting >170Hz frequency. Should I replace the sensor?
Thanks!
