Wideband reading wrong(I think) HELP
I bought a Autometer Ultralite Wideband... Its reading stays between 14.6 and 14.9 all the time.. Does anybody know how to fix this or calibrate it? I tried their website to no avail.. Any help is appreciated

to check the sensor take it out of the exhaust spray a rag with some breakeen and put the tip in the rag it should go full lean, if it does not double and triple check all your wiring, if still nothing try another 02 sensor, my AEM did this and ended up being the sensor was shot
also im not sure on this but i know my AEM didnt need free air calibration but maybe the autometer does check the directions

You should put the O2 sensor as close to the engine as possible. Mine is the first sensor, followed by primary, than secondary. I get P0420 from "high-flow" cat, shouldn't matter to O2 sensor.

i was gonna say move your wideband sensor to before the cat and not after as you'll be getting scewed readings that way. and would make sense especially if your second O2 sensor is before the cat then that will through the P0420
