Have used it for several tunes, now nothing showing up on the guage at all. Guage is less than 1 yr old...ideas?

 

Do you have any lights on the gauge? Maybe a wire came loose or unplugged. I'm pretty sure these gauges have diagnostics built in them and flash numbers when they detect an issue.

 

Rechecked to wires to the fuse box..looks intact. Nothing on the guage. No lights no readout...looks like it is sitting out of the car in a box.

 

run a wire from the battery to the power wire and see if it still works.

Anyone know what the resistance across the sensor should be? I need to check mine as well.

 

sounds like the gauge is either not powered or dead.
first thing i would do is use a multimeter to check if you are getting power.

could be the a bad ground.
if it was fused, it could be that popped.
if it wasn't fused, there is a small chance the gauge is popped.

 

Wow that is very strange, I've had my AEM UEGO in my car for a few year now with out an issue. Like the others say check out the basic and go from there.

 

Call aem get them to replace it, should still be under warrenty
