Check Engine
Hi
I have a 2002 RSX Type S
My Check Engine light went on after 60K miles. I took it to a mechanic he said its the o2 censor. Then I went to another mechanic he said there is nothing wrong with my car.
Is the O2 censor really necessary to have? Seems like mechanic didn't even know where to get one.
I also changed my battery and now my radio is not working. Asking for some code.
Does anyone knows how can I fix that.
Any idea on how to reset the computer so the check engine light goes away.
Thanks

It'll go on and off as the O2 sensor fails, then eventually it'll just stay on. I had mine replaced at 125k miles and my mpg has gone up considerably.
If you don't have the radio code in your manual or written down somewhere, the dealer can get it for you but they'll need the serial number of the radio which is on a sticker on top of it. I highly recommend pulling the radio out yourself or else they'll charge you labor for it.

36531-PRB-A01, it's 242.56 at acuraoemparts.com. And they sell a Denso OEM replacement for 180 at ... well, just search for "Denso OE Replacement Primary O2 Sensor" on google and you'll find it.

If the CEL came on a code was stored, without knowing what code was in the computer there is no way of diagnosing this. There are literally thousands of trouble codes for OBDII cars, many items are very simple, others are much more involved. Based on years of working on a garage I would estimate 80% of all CEL codes are related to the Evap system, which is usually simply fixed by tightening the gas cap or the customer admitting they filled the car with gas while it was running, or over filled it and flooded the charcoal canister, with the remaining 20%, I'd say 40% of those were simply glitches in the system, often the tolerance for the system to throw a code is very slim, if water can work its way into a plug/socket and changes resistance for just a millisecond when the computer is checking that system it will throw a code. If voltage is higher or lower then it is suppose to, if the planets are not aligned it may throw a code... In short, I wouldn't go throwing an O2 sensor in the car unless you can verify by code number what the problem was. If it is a faulty O2 sensor, it will certainly come on again, go to autozone or some place like that after it comes on, they check codes for free and find out what the actual problem is.

If it's the code for an upstream oxygen sensor (pre-CAT), you should replace it as it's potentially harming your fuel economy. When the oxygen sensor on my car was failing, the CEL would come on. I reset it, but it came back on after a few months so I just replaced the sensor. It's a fairly easy job if you use an oxygen sensor socket, which is available for free rental at AutoZone.

As to the radio: If it's the same radio the car came with, try this site:
