Hey all
I need help on the aem uego. Just installed it and all the guage read is 14.7 not even moving during driving or just idol. The question is do I have a bad o2 sensor.(o2 sensory is installed on a testpipe) I bought it new but let a friend used it for a summer. Tried searching but cant find any help.

thanks in advance

 

Make sure the plug where the 02 Sensor and harness for the gauge connect is together all the way. I suggest getting it as tight as you can, and then run a wire tie around it to make sure it stays together! That little clip is worthless. Then tape it up for protection. Mine has done this before and that was always the problem. Wire Tied it and havent had a problem for 7K+! Let me know if this doesnt work.

 

Very odd. I have never seen any problems with the gauge with the bunch of people i know have one. I would contact AEM. Maybe you got a bad unit. If you have power and the sensor is plugged in correctly it should work.

 

Thanks for you help. celica2evo you got it right on it was the two connectors not connected tight enough. That clip is worthless. once again thanks for your help would a never thought of rechecking the connectors.

 

when it goes bad it will do the same thing or read something constant most of the time!

i've been thru several sensors!
