Bad Flooding Yesterday.

I had some bad flooding yesterday, the truck had to end up going through some heavy water.

Since today, on first restart. The car didn't run smoothly. It seemed to hestitate on first drive alot. Once it got running it seemed to become smoother. Also I noticed, I don't know if im just being parniod that when I put the car in N the car stayed at above 2k rpm. Now as the car idles right now, its not doing that in N its operating apprently fine.

I've been home for 15minutes or so, and have been letting it idle. Its sounding alot better now, but a error code has poped up with check engine light.

Its reading P0134, "H02S Circuit No Activity Bank 1 Sensor 1".

Anyone start me in the right direction . And what I may need to replace, I know water got in the engine area. My battery was wet but could be splashing. I can't remember how high the water was, but there was a stuck bmw in front of me lol.

My baby was running smooth as can be in the mornings before this.

Now again, this is the first start after the rain flood thing.

I have a 99 Honda Passport.

That much water would submerge you O2 sensor and its wiring harness. Crawl under your rig, disconnect the harness, clean it up, put some dielectric grease in there, and see if your sensor starts sending its signal again.

Is there anywhere to tell if its the back sensor or front? Becuase I JUST recently had the back replaced. The Front are the orignal ones.

I just reset the error code. The car is running perfectly fine right now. It was just this mornings cold start, its starting fine right now to.

Ill give the cleaning job a go.

Sure. It's the front one for bank one (passenger side). It may be fine when it all dries out.

If you went through enough water that your battery is wet; I'd also check and change your air filter for sure, if this got wet, and you're running it, you could be sucking in water - not a good thing.

Also check 1 or 2 spark plugs to make sure they didn't get wet; you should be ok on auto tranny fluid, as long as the truck wasn't submerged for more then 3-5 minutes or so.
