    Wideband 02 sensor bad?? Crazy AFR reading

    I got a power commander with the wideband 2 had it on my grom bout a year and a half and just recently the gauge reads normal 13.5 but now it starts to jump to full rich then back then lean its all over the place. I took it out it was somewhat carboned up sprayed it with some brake cleaner made sure it was dry and put it back in. And still doing the same thing maybe worse now. Not sure if itís good yet might just buy a new one. Anyone else have a problem like this???

    I've been through 5 or 6 wideband sensors in just under 2 years. If they get wet, they're done. I use a Brock's exhaust, which has the opening facing up. If I ever forget to cover it and it gets rained-on, my sensor will be dead the next day. Expensive lesson to learn for me!!! Did yours maybe get wet?

    Just go down to AutoZone or any of those box auto store and get a Subaru O2 sensor, I posted the part number on here some years back I think they were Bosch 17018 and the other p/n on the box is 02580070184UG they were like $54-64 back in 2015-16 time fame

    Yep. Gotta be careful with the rain and these sensors. I actually made a tail pipe plug and a waterproof sock for the end of exhaust for overnight and whenever it might rain. Combine that with a bike cover and you're golden. The Bosch 17018 will work well, but make sure to price it out at a few different auto stores (O'Reilly's, Autozone, Advance, Napa, etc....). I've seen the pricing vary by $50 at those stores for some reason?
