wizard- yes, very easily, do u have o2 extensions on it? if so, unplug em let em dry out or blow them out, and fill them with di-electric grease, the water gets the connectors wet. happened to mine everytime id get the undercarriage wash at the car wash, lol. its also possible for them to get wet where the wire goes into the top of the o2. shrink wrap is your best defense in that case. lmk if u got ne other ?s
