 This is a simple analog (0-5v) input to the ECU.  No significant load on the sensor is illustrated in this diagram. This is a simple analog (0-5v) input to the ECU.  No significant load on the sensor is illustrated in this diagram.

 This is a 0-5v input to the ECU but with a pull down through some resistor. ​ 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 through some resistor. ​ 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.

 +When nothing is connected to this input, the ECU is going to "​see"​ ground (0v).
