I just recently added an ms3pro pnp to my car. I have an LC2 wideband that I wired into the window switch 12v and ground. My tunerstudio AFR gauge is stuck and pegged at 7.4 afr. I made sure the correct I/O was specified under EGO control. I made sure the correct innovate preset settings were selected.

My signal wire is connected through the options port, on analog input 2.

I used a multimeter and saw that a constant 0.1v are going to the signal wire from the controller regardless of me changing my afr table and revving the car.

The yellow wire is by default the 0v = 7.35 and 5v = 22...

What could be the problem? Could it be the sensor itself?

Thank you.
