I just had my check engine light go on in my 1998 civic and then at Autozone they plugged in their gadget and found out my civic had a bad O2 sensor. I then discovered that there are not one, but two O2 sensors. The Autozone manager said that we should replace the one closest to the engine first and then test it... he said that 90% of the time that one goes bad due to the heat of the engine. We did that and the engine now runs well.
It can actually be multiple things on a Honda. Typically, it will be your primary O2 sensor, your fuel filter being clogged, or the fuel pump not supplying enough fuel to get the job done. Also, contrary to what another answer had said, the O2 sensors are NOT in series. The front (primary) O2 is used to fine tune adjustments and the rear (secondary) O2 is used simply to verify the catalytic converter is doing its job.

* It could be a faulty check engine light or a light sensor problem . There's probably not a problem with the engine at all just the faulty sensor light problem most likely. * ----------------------------------------------------------------------------------------------------If your check engine light stays on with the engine running , a malfunction with the emission control system has been detected.
