You have 1 O2 sensor.

It's located underneath the car, just before the catalytic converter.

As I just posted in a thread about running rich...
DO NOT USE A BOSCH O2 SENSOR. It will not sovle your problem, I tried 3 of them.
Get an NTK from Summit Racing ( cost me $70 shipped to Ga.) it was actually cheaper than the Bosch and solved all of the O2 related codes and the rich condition.

x2. Never use Bosch o2 sensor for OBD I cars, especially Preludes. Always NTK(NGK) OEM O2 sensors.

It's not that they are bad, it's more of a, "hit or miss" by using a Bosch O2 sensor for an OBD I Honda. For OBD 0 (88-89) Bosch o2 sensors are okay.

I was running a Bosch O2 sensor for about a year or so until it gave out and gave me code 43. They also make the car run more richer than necessary.

Re: O2 sensor

OBD stands for On Board Diagnostic. The "0" is the first generation of OBD(more or less), so mechanics would and can diagnose cars easier by checking fault codes and then referring to their manuals to pinpoint the problem(s).

OBD I is an upgraded version found up until 1995 or so(in the US). After 1995, OBD II was introduced...instead of looking up blinking codes, technicians plug in a diagnostic tool which just tells them what's wrong lol!


...this is why the correct o2 sensor is important for optimum performance of your Prelude. :scratchchin:

Re: O2 sensor

If the motor is OBD I, then you need to convert via a conversion harness.

We're getting off topic...
