meangreenmachine Posted February 25, 2007 Share Posted February 25, 2007 Here in northeast iowa it is blizzard conditions but I can drive anywhere because I own a pathfider! So im playing in about 8 inches of slush on a main road when my cel comes on and I have no power in the low rpm range. I have a whole new tune up: plugs wires cap rotor air and fuel filters. I noticed while puting exhaust on that the metal insulator on my o2s is loose and slides around. Could water be getting in there and shorting something out? It almost acts like a bad tps or map sensor but it is very intermittent. Thinking back I also had this problem puddle jumping when I first got it but then I tuned it and it hasn't happened since but I haven't really gotten it wet since then. Does the ecu store history codes as the cel comes on then goes out again whenever it feels like. Link to comment Share on other sites More sharing options...
denisb Posted February 25, 2007 Share Posted February 25, 2007 If it's an O2 code I'd suspect an engine code afterwards. I'd suspect wet plugs, alternator and/or alternator if you were going through the water/slush fairly quick. Denis Link to comment Share on other sites More sharing options...
88pathoffroad Posted February 25, 2007 Share Posted February 25, 2007 Yes, the ECU stores error codes. Check them and report back! Link to comment Share on other sites More sharing options...
meangreenmachine Posted February 27, 2007 Author Share Posted February 27, 2007 Well I pulled the codes out today code 33 o2s. So tommorrow I get to battle getting the original one out. I have planned on putting one in and have had it sitting on my toolbox for quite awhile but put it off because the original is rusted in pretty good there are no flats left for the 7/8 wrench. I guess its time for the gas hatchet and my trusty vice-grip! Hopefully this will take care of my no power problem I have found a nice deep puddle to test it out so we shall see.

nissandoms47 Posted February 27, 2007 Share Posted February 27, 2007 just rent the 02 sensor removal tool from autozone. Link to comment Share on other sites More sharing options...
meangreenmachine Posted February 28, 2007 Author Share Posted February 28, 2007 Well my memory served me wrong. The o2s was in good enough shape to get a wrench on but the o2s bung was just about rotted away. I didn't think there was much material left for the threads but with a little finesse and some patience I was able to heat it up and get the old one out! I used an ac delco universal sensor. Screwed right in. Connected the wires and out for a test drive. Hit every piece of slush snow or puddle I could find for about 30 min. No hesitation or cel :cool2: The old sensor had broke right where the three wires go in. I could pull the piece of metal up and see the three wires where the were connected to the sensor. Slush or water must have been getting in there and the only thing I can think of is that it shorted betweeen the heater and sensor signal. Link to comment Share on other sites More sharing options...
k9sar Posted February 28, 2007 Share Posted February 28, 2007 good deal. My pathy gets tempermental until I hit mud puddles. damndest thing. At the NorEaster, it ran like crap after the first day at Rausch Creek until I got to Paragon and hit the first puddle. CEL went out and she ran like a champ all day. My gal just likes to get dirty I guess. Link to comment Share on other sites More sharing options...
