removed my downpipe with my 02 in it... threw it in the trunk. swapped the engine, put it all back together and now...

the AEM wideband ONLY displays 3 dashes. it does not go thru the start up procedure of counting down, and the little light for lean/rich flying back and fourth. even AEM couldnt tell me what they think it is.


this sensor/gauge has never given me issues before... i just cant understand what could have gone wrong. AEM says that with the 02 unplugged, it should still display 14.7, and go thru startup procedure.

its wired into my other AEM gauge power/ground/ecu, and that gauge is working fine, no issues, so i dont see there being a power/ground issue... but maybe im wrong?

any help is great,

thanks

 

So you tried it with both sensor connected like it should be and also with sensor disconnected and still same result?

 

***okay im about to do the internet version of a walk of shame... i am better than this. lol.


soooooo turns out its an autometer wideband, not an aem. i use an aem multi gauge above that and forgot i was running 2 different brands... but it gets worse.


i was only testing it with the key ON>... and i have the white wire tied into the AEM V1.... so it wasnt getting signal until the engine was running! once i started the engine for the first time, it immeadiately worked. i feel very stupid.

but, i appreciate your response in trying to help this dummy.

 

It was an easy fix at least
