You need to replace your ELD....I had the same code after turbo install oddly enough. Honda use to make you buy the entire fuse box....now you can just replace the ELD unit...here's part #
DTC P1298 Is Stored in the ECM/PCM
(Supersedes 05-006, dated February 25, 2005, to change the CR-V model-year range)
DTC P1298 (electrical load detector (ELD) circuit high
voltage) is stored in the ECM/PCM.
The electronic load detector (ELD) has a faulty solder
Replace the ELD.
NOTE: Previously, if an ELD required replacement, you
had to replace the under-hood fuse/relay box. To
reduce repair costs, replacement ELDs are now
Electronic Load Detector:
P/N 38255-S5A-003, H/C 7987571
You may have the high voltage for the 02 because of the ELD....I would replace ELD, reset ecm, & test drive....see what happens. Unless you have access to a scan tool with real time info to look at 02 sensor values.....

This thread is about a year old, but I have the same problem. Mine is a 2002 Civic Si. Is it the same part number? I also was advised that it was molded into the fuse box and the whole thing would need replacement. Can I dissassemble the fuse box- remove all the fuses/relays and connectors- and inspect the ELD? I can solder. What does it look like? Is it located between the alternator and the fuse box? Fuse box and battery? How common is this failure? I had 2-3 things go bad on mine all of a sudden at 90k miles. Did the faulty ELD distribute bad voltage and harm my sensors?
