The MIL is on. Codes P0135 and P0141 are reported for each sensor. The sensors have been replaced. The PCM has been updated. The fuse box has been replaced. The problem persists.
Honda isolated the problem to no communications signal at fuse 4 in the cabin fuse box and recommended replacing the fuse box. That was done along with all their other suggestions. All that has been accomplished is that Honda has drained more money out of my economy.

P0141 code, replaced sensors multiple times, checked fuses, wiring, measured O2 sensors w/ meter,computer o.k., just bought another sensor from dealer (no warranty...go honda!) going to replace sensor in cat. again. If it doesn't fix problem car is going for a downhill drive off of a short pier!!! NEVER OWN A HONDA AGAIN!
