Oxygen sensor in 2004 Honda CRV?

Question

How do you tell if it's bad? Can it be tested?

Honda guy, the check engine light was on/went off the day before the 60K checkup. I mentioned this to the dealor and was later told it needed replacing (it cost a fortune, by the way) and I'm not sure if it really needed to be replaced or if it was replaced for pure profit motivation.

Zephyr, I agree with you. I feel like I made a boat payment for someone. I bought the Honda because I had a '91 Integra that I sold with 312,000 miles and no major issues the 12 years I had it. I will take your advise and find a Honda shop that isn't a dealer.

Brandon, I wasn't trying to belittle you, but was making fun of the ultra goofy who pollute with impunity because they bought a carbon credit to do so. I've seen bumper stickers on gas hog cars that say "I've negated my carbon footprint by using carbon credits" Not exactly quoted, but this is the jist of it. I use the flourescents also, but only when the original bulb dies. I'm not throwing them away until I use them up.

Answer 1

the oxygen sensor can be tested for response rate but you in all probability don't have the tools to do the test.

On the 2004 CRV the on-board diagnostic system tests both the O2 sensor heater circuit and the operation of the O2 sensor every time the vehicle is driven. If there were a problem with the sensor the check engine light would be turned on by the OBD II system.

I don't know what problem you're trying to fix or why you ask, but if there were a problem with the O2 sensor the check engine light would be ON. That sensor is under factory warranty for 3 years or 50,000 miles whichever comes first.

hope that answers your question

Answer 3

Did you ask for the print-out of their diagnostic report? If the O2 sensor was bad, the report would show that. Sorry, but You just might have been ripped off like I have been before. I am the original owner of a 1985 Honda CRX-Si with 290,000 miles on it and did not have to replace my factory O2 sensor until around 100,000 miles and I actually replaced it myself using an O2 socket that is similar to a spark plug socket, but has an opening down the side of it to accomodate the wire. No check engine light...just did it because of the milage. From my personal experience, I learned long ago not to go to the dealers in my area (Georgia, USA). Every time I took my car to one of them, they always 'found' something wrong with it. $$$$$ I guess. I asked around, did my research and found trustworthy independent shops and finally a Honda specialist repair shop to do the work. Also, I never followed the 15, 30,60,90,120 thousand mile maintenance schedule and my CRX still purrs like a kitten and runs like a mini-rocket. If you look at what they do for your hard earned money, it is 80% 'CHECKING' things...like 'check' fluid levels, 'check' belts, 'check' tire pressure, 'check' brake pads, 'check' air filter, 'check' wiper blades, etc...etc. Get my point? You can do most of what they 'check' and it would be free! Just my personal experience and I know everyone is different. Hope this helps somehow, and enjoy that Honda...they are awesome vehicles.

Answer 4

Hello you have recently answered one of my questions I've posted about Barack Obama and the issue's on global warming. I would like to reply to your response.

First of all I haven't bought any carbon credits

Second of all I believe in reducing my carbon footprint in other ways such as driving less, buying LED and Fluorescent light bulds, recycling, and use the least amount of energy as possible.

I just thought you should know the facts about me.

look up the drive cycle for that car and match that for 3 days. after that, all of the monitors should have run to completion. a scanner can only check for codes and clear them but that would put you right back to where you are now.
