I came across this with my 98 Civic a few years ago. It should have 3 or 4 problem codes, and when I googled all of those together, I found someone who had a webpage for that exact problem. Its a very cheap fix. There's a wire harness behind/below your intake manifold that is rubbing against a steel bracket and its shorted out, causing that problem. I don't remember which fuse it was, but if you check your fuses under your dash you'll also notice one has blown.
Because of its location I couldn't easily get to the harness without tearing alot of stuff out. I could, however, get to the bracket, so I unbolted it and wrapped it about 1/8" thick with electrical tape and put it back on. Looking back, putting a split piece of radiator hose or something slipped around it would've been better, but this has worked fine for me for about 4 years.
Hope you see this fast enough.
