B3mwe Posted October 16, 2020 Report Share Posted October 16, 2020 I'm in the process of my g4 install, I have an fault AN V2 at GND I had an Alcatel ecu previous and it has the iat 2 pin sensor wired into the maf wiring What have I missed Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 16, 2020 Report Share Posted October 16, 2020 AN Volt 2 is the original MAF input. The error means there is zero volt coming in on that pin. If it has a temp sensor connected it would have needed a pull-up resistor wired in. Maybe the Alcatek had a pull-up resistor fitted internally to that pin so it could only be used as a temp input and nothing else? Your option would be to either fit a pull-up resistor in to the wiring (probably near the header plug on the ecu is easiest), or get an expansion loom and connect your temp sensor to that instead (it has 2 dedicated temp sensor inputs).
