So I have an AEM wideband gauge that is a few years old. I have replaced the sensors about 2 or 3 times, no big deal. Fast forward to today. I replaced this sensor and the gauge worked perfect (perfect as in it was telling me the sensor was bad by how it was reading) before I replaced the old. Now my gauge just reads like 14.9 or abouts. I was told if things werent connected it could do this, but I have triple checked everything and I am thinking the gauge is bad. I am going to check to see with one of my friends who has the same gauge and see if it is truley the gauge or if it is something else, before I go buy a new gauge. LMK if anyone has any comments or thoughts. Thanks.

mine sensor just failed.... it oscillates quickly between 14.9 and 15.6 or so. On the data log it will show 14.2 during pulls.

 

When my gauge failed it completed stopped working & nothing showed up on the gauge...I had to replace both the sensor & gauge...I've had my AEM Wideband in my car for probably 3.5 yrs now...

 

Well the sensor is new and the gauge itself is quite a few years old, so idk. It looks and sounds like it might be the gauge, but we'll see after I check a few things. Thanks for the replies.
