### PWM signal

#### Ethanol content

- Frequencies between 50 and 150 Hz correspond to ethanol content between 0 and 100%

- Frequencies between 170 and 190 Hz are reserved for sensor faults.

#### Fuel temperature

- Fuel temperature is transmitted as duration of low pulse

- 1ms pulse corresponds to -40*C (-40*F)

- 5ms pulse corresponds to 125*C (257*F)
