AEM Wideband sensor replacement

I have the same AEM wideband and mine uses the 4.9 sensor. Mine was stuck at 14.7 and my sensor was bad. I bought replacement from amazon. Just bought a sensor, it was $38 I believe. There are some good videos on how to check it before you declare it bad. The new sensor cured my issue and it has been working so far, 2 months or so.
