Had a problem w/ no voltage reading on my B18C. Whenever I hook up the Hondata and look at the O2 voltage, it reads 0. I do not have any CEL.

So, I finally remembered that I used my 93EX 02 sensor for the swap. So, went ahead and ordered a new replacement for the GSR from NGK.

So while I am waiting for it to arrive, I took out the 02 sensor and started the car. Hondata is reading 3.8V steady. Weird. Also, CEL obviously comes on.

You guys know if the Civic EX 02 sensor is not compatible? Just curious while I wait for my new one to arrive.
