Primary o2 sensor fault
i have aem ems with the aem wideband, i switched to stock ecu to pass inspection but i get a check engine for primary o2 sensor fault. i looked under the car and both the wideband and stock sensors are on the header.
what could be the problem?

if its an standalone AEM wideband connected to the AEM ecu its probably connected to the same pin as the factory o2 sensor. Unplug the AEM wideband control box.
Best to remove unused sensors as running them when they are not connected to a wideband controller tends to soot them up.
