I have this AEM EUGO gauge for over a year, now all it's showing is a constant 14.8, no matter what, even with sens unplugged. I tired disconnecting it and reconnecting it a couple of times but it's always the same reading 14.8
Anything that can be done to fix this?

 

Most likely your sensor is bad. You just need a new sensor. You can get it for around $69.93 from aemonly.com or you can look around they also have free shipping.

Check the link below to find out how to check the sensor.

I know this is old, but I can't seem to find any other thing to help me out. My gauge is doing the same thing. Mine is reading a constant 14.6-14.9 no matter what I do. If the sensor is in the exhaust, in my hand, in a rag with brake cleaner or completely unplugged, it reads 14.8. I've tried 2 different wideband sensors and still have the same issue. Any suggestions? Thanks

 

If you tried a new sensor and it still is acting like this. Take the gauge out and make sure all your wiring connections are correct and not pinched, cut through anywhere or simply unplugged from the back of the gauge. If everything is good just give aem a call at 310-484-2322
