| This is a 0-5v input to the ECU but with a pull down to ground **and** a pull up to +5v through some resistor combination. The implication here is that any voltage source (sensor) connected to this input will be expected to drive the load of that pull down. Some sensors simply can not do this. You can get more info on our [[ecuinputdata|ECU Input Data]] page. | This is a 0-5v input to the ECU but with a pull down to ground **and** a pull up to +5v through some resistor combination.
