Continental 13577379 flex fuel sensor

Hi.

I just fitted a continental 13577379 flex fuel sensor, the link storm is reading between 30 to 32% of ethanol on the pump fuel.

The tank was drained today and I put in a new fuel (99 oct E5) and it is still reading over 30%.

The reported ethanol content comes from the frequency of the signal from the sensor.  They all use the same calibration as far as I have seen, 50Hz = 0% Eth and 150Hz = 100%.  You can see the frequency that is being received on the Digital tab of the runtimes screen.  I would say if you have more than about 60Hz showing on the DI then either the fuel is contaminated or it is a fake or faulty sensor.

Hi Adamw, I replaced the sensor and it works fine now thanks for your help, not sure if it was faulty or fake but I bought an innovate sensor(SE1004S), at least it should be genuine sensor.
