Car Forum / Honda Cars / December 2005Oxygen Sensor
Hello people! I have unfortunately fallen into the hapless section of society facing both a cash crunch and car trouble at the same time...looking for salvation here. :) I need to replace the oxygen sensor on my 1996 civic HX... is this a task uncomplicated enough for me to undertake armed with a set of tools? My skills : can use tools and can comprehend clear legible instructions. Will something like a Haynes Manual give me the required know-how for the job?? Suggestions/tips are highly appreciated. I'd be sure to soak it in a good penetrant (like Kroil) oil way in advance -- it will cause some smoke when you fire it back up, but it will be worth it. You'll need a special socket for it -- The do sell (possibly rent) these sockets at part places Sometimes you need to heat the socket to get it out. Also be sure to not crossthread the sensor - a friend of mine did that and it really didn't want to come back out well. I'd put some anti seize compount on the thread before you put it back in. Make sure that compound doesn't get in contact with the sensing portion, because that could ruin it. Also be sure to properly torque the sensor.

Also, is your rad and reservoir full, have you checked carefully for vacuum leaks under the hood? Give the actual CODE numbers too (not the interpretation). 'Curly' I'm interested in your comments below re Oxygen sensor..."is your rad and reservoir full". I recently had the check engine light come on in my '02 Toyota Sienna. The dealer is telling me it's the Oxygen Sensor and wants to charge me almost C $500 parts & labour to replace it. Your comment caught my eye because when I first got the warning light I looked under the hood and noted that the reservoir cover was off and there was No AF remaining in the container. I filled it as per owner's manual. The dealer insists this is unrelated to the Check engine light. I was wondering if you had some particular reason for asking if the rad & reservoir are full ? Thanks, Roni >> Hello people! >> [quoted text clipped - 11 lines] > >'Curly' > Hello people! > [quoted text clipped - 9 lines] > > Suggestions/tips are highly appreciated. It's simple to remove it. An O2 sensor wrench would be easiest if it's stuck on but mine came off easily with an adjustable wrench. If it's failing because it's slow, you might be able to clean it. Fill a stainless steel pan with 1/3 Lime Away tile cleaner (acid) and 2/3 purified water. Drop in the whole sensor and boil lightly for an hour or two. Rinse thoroughly and boil it two more times using only purified water. Mount it on the car and immediately drive to burn off the water. I've done it twice so far. I figured the second time would ruin it but it still works perfectly. That's a neat trick -- I'll have to remember that one. Thanks! Remco > That's a neat trick -- I'll have to remember that one.

My 88 Toyota Tercel cracked its sensor. There is a lot of mechanical, thermal, and chemical strain on it. Cleaning only works if the sensor is covered with ash but otherwise good. It could also destroy it. Try at your own risk :) no problem to replace,go to local auto zone and rent a oxygen sensor socket.clear code if ck engine light is on Hey guys! I finally managed to pull out the codes from my 96 Cvic. Only code that came up was PO135. It also says O2 sensor heater circuit malfunction (Bank 1 Sensor 1). This is just after I got a new post cat. O2 sensor. Can someone tell me whats goin on? My vehicles OBDII. > Hey guys! I finally managed to pull out the codes from my 96 Cvic.

My vehicles OBDII. boo-yah! i had the same exact thing, 98 civic hatch. you want the top O2 sensor, that screws into the exhaust manifold. the one youre staring at when you open the hood. why did you change the post cat one? did you get a code for that, too? my post cat is still good. anyhoo... mine started failing slowly, and resetting the light caused it to be OK for shorter and shorter amounts of time. a week, 3 days, 1 day, then the MIL stayed on. car wouldnt idle right, either. stalled at stop signs, etc. so i bit the bullet, and called around. i wanted an OEM one, since ive had the car since new. napa, autozone, etc didnt have one in stock- sold out. dealer had one, for bout $200. so i got it, and 10 mins later, everything was back to normal. BTW: that was last summer. took the biennual smog check (california) a month ago, and passed with lower numbers than i did 2 years ago! so yeah- the O2 sensor does something! > Hey guys!

This is just after I got a new post cat. > O2 sensor. Can someone tell me whats goin on? My vehicles OBDII. It means the UPstream (pre-cat) O2 sensor's heater has failed. This means the sensor is now relying on exhaust heat to warm it up, just as if it were a pre-'92 single-wire sensor. This will increase emissions for a minute or two after startup, so it doesn't mean much in the long run, except that you won't pass smog with error codes stored. The post-cat sensor just measures converter efficiency. SignatureTeGGeR? The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |
