Hi,

I think you should use the Sensor Request Form. Be sure to ask about your rear o2 sensors.

We have found a few Hondas that are using both sensors for air/fuel ratio calculations. You may need to treat both.

You definitely must treat the upstream AFR sensor. For that, you need the Wide Band EFIE.

But just last week we had a couple of guys with late model Hondas get check engine lights, that were saying the downstream o2 sensors were showing too lean. When we looked them up, it turned out they were being used in air/fuel calculations.

So, to be sure, get your particular car looked up.
