UEGO Wideband Problems

Hopefully Im posting this in the right section.

Anywho, I have an AEM UEGO wideband gauge that has been giving me issues since I installed my Apexi TT. The gauge didnt display at all after I installed the TT. Come to find out, the power wire had come out of the fuse slot. Problem fixed right? Well, not really. Now the gauge displays, but its stuck on lean. I noticed the white wire (0-5v) was unhooked and hanging. The AEM manual says its optional, primarily for data logging so that shouldnt be the problem, right?

Any suggestions?

I don't know much about those gauges but it sounds like you may have shorted it out, more then likely shes gone?

Might try that. It seems to want to read a lil better today. Its actually reading where it should at idle (between 14.5-15) still getting shotty readings at WOT and partial throttle though. Im still leaning towards a sensor.

I would check the power and ground over again.. The white wire isn't used on the stock ecu and the blue wire is for logging.

Cheers!
