I am using a 4 IR Avoidance Module. When I am using 2, it works fine, but when I insert a 3rd one, the sensor is not working properly. I tried calibrating it with the potentiometer but there is no luck. I transferred IR no2 to no3 to test if no3 port is working, and it is working well. Any fixes?

Any code ?
Any schematic ?

You have not provided any of circuit any of the code or also detail of your project

Is your code looking only at the first two sensors and not the third one?

Hello @idontknowhowtouse
I am quite sure I found your code... perhaps your #3 IR Avoidance Module is not plugged in correctly. Check again, or maybe post a photograph here.
