    Hi - I have the same problem. I was at the dealer and asked if they could tell me what was wrong. They charge 99 dollars but I opted out of this. What a rip off!

    Okay this may sound like a stupid question..... how long can I go without really replacing the Oxygen Sensor?

I got the same computer reading on my 2002 rsx-my emissions reading was just fine. i have done nothing about replacing and/or repairing the oxygen sensor for the past year and no surging or anything. i also wondered if using ethanol gas had anything to do with messing up the sensor as it was too much of a coincidence that after using two tankfuls of ethanol gas, the engine light came on

If you have an Autozone nearby, they will read the problem code from cars computer for free. I've got 2002 RSX base with 71 K and the problem code I have is the oxygen sensor. I looked around and found one for just under $200, and I plan to install it myself. All needed is a sensor wrench that I think I can either buy for under $10 or borrow it from one of the auto parts stores that lend tools.

Mine had the same problem at 30,000 miles, it was in fact the O2 sensor. I had it replaced and haven't had the CEL since. I've noticed that RSX's have this problem quite often, so don't be too surprised.
Let me know if this helps.

I replaced the serpentine belt on my 2002 accura rsx type s it sqeaks and seems loose is there any way to tighten it....tks

The tentioner should keep the belt at the right tention. Are you sure its the belt? I had some squeaking in my 05' RSX and replaced the Tentioner Pulley and the squeaking went away. Maybe this could be the same case. Hope this helps.

2003 acura rsx. my maint. light just came on the other day. my stock alarm only works when it wants to and the passenger side air bag light comes on randomly. im thinking there is some kind of electrical...

It's possible that there's a short someplace. You'd have to take it to the dealership for a diagnostic check. This will cost you money. Electronics in these cars is not an easy fix. The random side air-bag thing happens in our cars often. It's a bug in the system but doesn't mean anything is really wrong with it. Happens to everyone I know that has an RSX, which is about half the people on the forums in (your problem may be different than anyone elses)
Check the forum there, people may be able to help you far more than here.

I have an acura rsx type s 2003 and the fan that blows the ac and heat stopped working. The mechanic says there is a computer in the dash that controls this and it will cost 450 dollars. Is he being...

It doesn't sound good, does it. I honestly couldn't tell you, but he should have checked the fuses, resistors, and your blower motor before he told you that one. If he didn't, go elsewhere. What you should do is get a Hayne's repair manual, and check it out. Or, get a test light, and do some checking. First check the fuse and see if there is power to the blower motor. If there is, then check the resistors, and if they are okay, then the blower motor itself is no good, and will need to be replaced.
Going to a mechanic is just like going to the doctor. It's always good to do your homework before you go so that the doctor and his best friend at the drugstore don't get too many free trips to Hawaii.
I really think a repair manual would help you.

Regarding the heating issue, sounds like your thermostat is stuck open so the coolant isn't heating up. (May need replacement) Does your engine temp guage show it running colder than normal?
