My wideband has worked perfectly for months but now it is starting to act up. When I first tturn on the car it will work and read the right afr but about 2 minutes later it will just turn all the way lean and not read the afr anymore. Im not sure what happened. Has anyone had this happen to them before? Can anyone help me try and figure out how to fix this. Did my wideband completely fail on me?

 

Be sure to check the connections, and the grounds etc....... When the sensors are done they usually read lean none stop in my experience.

 

you could at least mention what brand of wideband

do you run...
meth?
race gas?

 

I have AEM and run pump gas. The car will read normal settings and then just stop reading altogether. On the ride home just right now it was reading perfectly for 15 minutes and then just went back to going lean. When I unplug the connection in the wideband it reads 14.7 nonstop and once I plug it back in it will read fine again for a while then go straight to lean.

^ good info

 

if my sensor went out already that is really weird. I've only put like 5000 miles on it.

 

5000 miles or 5 miles. Between race gas and it being electronic, stuff happens. There's been guys that have bought BNIB electronics and they were bad. Luck of the draw I guess.

 

I don't know about the AEM one, but the innovative motosprts LC1 WB could be recalibrated, I had to do that a few times. It was called free air calibration

 

aem uego is not capable of being recalibrated
