Want to run E85 and pump gas, or anything in between?
This sensor is a MUST HAVE!
This Ethanol Content Sensor measures the ratio of ethanol to petrol in a flex fuel vehicle. In order to adjust the ignition timing, fueling and boost levels, the engine management system requires information about the percentage of ethanol in the fuel.
A digital output signal is produced by this sensor, which can then be used by an aftermarket ECU (with appropriate flex fuel functionality) to determine both the ethanol content and the fuel temperature using just a single digital input on the ECU.
Using this information, the ECU can make necessary changes to the engine’s tune (ignition timing, fueling, boost pressure etc.) Even on applications where only one ethanol/petrol ratio is ever used, this sensor can still be very useful for monitoring and data logging purposes.
The sensor is installed anywhere in the return line between the fuel pressure regulator and the fuel tank.
3-Pin electrical connector included. Electrical connection consists of 12V, ground and signal wire.
The pinout is indicated on the sensor itself (from left to right looking into connector on sensor) as :
1.) Vcc ( 12V supply)
2.) GND (ground)
3.) Vout (digital signal out)
This Kit comes with a plug and the crimps, No wires included
Genuine GM sensor.
