How do I interface a sensor as shown below to ECU pin which has pull up resistor? Sensor is shown below, it is 3 terminal potentiometer. Inside ECU, before microcontroller pin there is a pull up resistor. We use this circuit normally to interface resistive input.
One way that I thought was to put a voltage follower circuit between sensor pin and before pull up. Please guide
