I am using several devices that use i2c to measure analog current and voltage from a pressure sensor(connected to ADS1015), position sensor (connected to ina219(0x41)), and to detect resistance on a gear motor (ina219(0x40)). All components have worked before many times, but now the current sensor that is connected to the position sensor is outputting "inf"" into the serial monitor. I have checked with a DMM that the position sensor and all current sensors are working normally. My code for my project is given below:
#include <Wire.h>
#include <Adafruit_ADS1X15.h>

//Adafruit_ADS1115 ads15;

Adafruit_INA219 ina1(0x41);
Adafruit_INA219 ina2;

I do not understand as to why the ina219 sensor is not responding to the position sensor. Any help tp troubleshoot is appreciated.
