AEM Wideband weirdness

[Smilez]

it just started today. car runs and feels normal. BUT the gauge is only moving a between 14.8 and 15.3 regardless of how much gas I give it. hooked up my laptop to the datalogit box and it's telling me the voltage of the sensor is only moving between 2.5 +/- .3

is my wideband o2 sensor done? gauge busted?

after watching that video, I went and turned my ignition to the ON position, which should send the o2 sensor to the --- full lean setting, which it used to do. now it doesn't stay there, it goes to 14.9 a few seconds after having power. then it just stays at 14.9. I'm going to send an email to AEM to confirm it, but it looks like the sensor is shot.

ew AEM!!!

It's common that the sensors bugger up after some time. I forget which tuner told me that. Anyways, they're cheap enought to replace if the sensor is bad. Check connections and cleanliness first.

When o2 sensor stops fluctuating quickly = o2 sensor is stuffed.

Most widebands use Bosch LSU4 wideband o2 sensor. The part number is etched on the side of o2 sensor.

is it fixable or do I have to replace it?

Replace it. Some say you can run engine lean?, burn off the deposits (I wouldn't do it). Normally the heater stops the o2 sensor from getting clogged.

hey man i had the exact same problem with my aem wideband on my integra. would go to 14.9 and stay there or it would either go to 14.9 than slowing count 15.0,15.1,15.2..... all the way to lean. basically my sensor was shot. i just warrantied mine at lordco but i think the guys above are right about a replacement sensor. you dont need to replace the gauge.
