Aem wideband
I have a aem wideband air fuel gauge I use on my 93 , it reads 14.9 and won't move. I have checked the wiring, it's good, its plugged in good. It will turn on and go through the motions but stays at 14.9? Any ideas ?

Yeah iv been trouble shooting left and right and can't figure it out yet. When the O2 sensor is unplugged it still reads 14.9? not sure if the gauge is stuck , bad sensor? I am not seeing anything wrong the wiring at the moment. My car was down over a year and now that im getting it back up and running, it's doing this. Before the gauge would read as should.

I would also reach out to AEM on this, give them a call. They may have some further troubleshooting steps to see if it's the sensor, the control unit, etc.

So I ordered a new Bosch LSU 4.9 sensor, plugged it in and the gauge started working again. So buying a sensor is the cheaper route then buying another gauge if anyone encounters a similar problem. Thanks again guys!
