Three types of ethanol content sensor are supported, the Link Ethanol Content Sensor (#ECS), GM/Siemens ethanol sensor and the Continental ethanol content sensor. Both sensor types require the Digital Input channel to be set to 'GM Siemens Ethanol Sensor'.
The Siemens ethanol content sensor can be wired as follows:
The Continental Ethanol sensor has a part number of A2C53344228.
The Continental ethanol sensor can be wired as follows:
For the Continental Ethanol sensor set the ECUs internal pull-up resistor to ON.
