Ok well the other day i spilt anti freeze on my car and it got into the connects of my 02 sensors. I cleaned them out after my cyclinders had been misfiring. After i cleaned them i waited for them to dry and all the antifreeze looked like it was out. But now when i leave my house at the same place a mile down the road my car starts misfiring and screwing up for about 1 mile. The check engine light is on and my scanner says 02 sensor High Voltage can anyone help me out here. Is there any fuses that i could check or what can i do?

alright i will replace it which one is it the one on the top or bottom???

the bottom one is just emission related and doesn't really determine how the car runs.

can you buy them like at a car quest or pepboys i am tired of ordering things and waiting

 
Rep Power: 811

I think so. Just ask them to look up your car info.

So the top one is the o2 sensor and whats the bottom one?

also gearbox what do you think do you think i need to replace it?

 
Rep Power: 811

yes you do if it says hi voltage, its not working right. bottom one is a secondary 02 sensor. if that breaks, the cel comes on and you won't pass emissions. but it doesn't affect performance. it's an "everythings okay" sensor. The top one determines a/f and stuff.

alright well i called carquest they estimated anywhere from 138 to 256 so i am gonna get it at torringtonhonda for 50 bucks after i replace it i will let you guys know if it stops. Do you think my dropping antifreeze on it caused this?

the crazyest **** just happened i lifted up the car to mess around with some stuff and i touched the 02 sensor i fired up my car and drove it i noticed it didn't bog i look down and the check engine light had gone of how the hell is this possible? I didnt unplug the battery and i didnt fix anything all i did was touch it and now its running good again. What sucks is i had already ordered the new o2 sensor

You should still change it anyways to just be on the safe side of things.
