What's wrong with my AEM UEGO?

[Tranman324]

Ever since I installed my gauge it does this. I thought it was a bad O2, but still does it when the new one arrived. So both my old O2 and new O2 sensors don't make a change.

When I unplug the sensor, it seems like the gauge works fine. It goes though the "111, 222, 333...." cycle and then displays "---"

At initial start-up, with the O2 plugged in, the gauge does not cycle through the start up... "111,222,333...". It just flashes the 1's like the clip before, but when I unplug the O2, everything is "normal"

Tried calling AEM three times, no luck.

PLEASE PLEASE PLEASE help.

i dont know much about the gauge itself, but if its brand new i would double check your power and ground. make sure they are good sources.

when i installed my friends i went to the ignition harness and had no problems are all. good luck

Oh yeah, i also tried wiring it up directly to the battery as well. No dice.

interesting.... is it new?

[Tranman324]

About a year old, I'm really really hoping it isn't bad. I would think AEM would have some kind of warantee or something....

[motoman399]

interesting.. i dont know if they would. a lot of time with electronics there is no guarantee cause there is so many people that know absolutely nothing about wiring and try to do it and screw it up. im not saying that is what you did, but that is why most places dont guarantee electronics.. good luck and let us know what aem says if you get through to them.

Odd.
It seems these have a 12 month warranty though, according to the manual.
