Ethanol Sensor Voltage Adaptor

P3 Gauges Verified independent store

→

The ESVA is a purpose built device that converts digital signals from a GM Continental style ethanol sensor to linear voltages, allowing you to use devices that need 0-5v input. To use with the P3 Gauge, simply select the "EC" (ethanol content) or "FT" (fuel temp) option for one of the two universal analog inputs. Not required for Flex-Fuel tuned GM vehicles - The P3 Gauge will read ethanol content directly and automatically over obd2 when activated by your tune. **Ethanol sensor NOT included** Show more
