Thread: wideband all used up?!?!

how can you tell when your wideband is shot?

It doesn't work.

Depends on the wideband, some have tests or calibrations you can do to the sensor.

But if the sensor itself is over 15-20k miles, you should replace it anyway.

i have had it since 2008 and have probably put 20,000+ miles on it since i got it. it reacts a bit odd sometimes but doesnt lock up but seems to jump around more then it should. i dont have anything to compare it to as i havent been on a dyno with the new trans yet. i do remember the last time i was on a dyno the afx the dyno operator used reacted considerably slower then my innovate. its a bosch sensor.

wrap a rag in break cleaner and hold the sensor in it, if the gauge doesnt change then replace

I noticed mine reads lean almost all the time. Happened right at the end of the season. Hoping a new sensor will correct this.
