My check engine light has been coming on intermittently. On my second visit to the Honda service center about this, a diagnostic test was run. The result: “CHECK AND FOUND O2 SENSOR BAD RECOMMEND REPLACING ($608.88)”.
I asked for a diagnostic code, but I was told that their system doesn’t give codes - only interpretations. From what I’ve gleaned from my web searches, however, there isn’t just one O2 sensor on the car. And from what I’ve read in this forum regarding other Hondas, sometimes a sensor is just loose or the O2 sensor code is triggered on the diagnostic test, but is not really the root cause of the problem.
I’ll have to resolve the problem because my car won’t pass inspection for registration renewal, but $600+ is a lot of money and I’m not really trusting the diagnosis. It cost a lot just to get the first diagnosis, so I’d like to get more information before I proceed with getting another, possibly conflicting diagnosis.
Can anyone suggest something I might check out for myself? I’m not a mechanically-inclined, but I can sure try if I only need simple tools and can locate the parts.
I don’t know if it’s relevant, but since I started commuting via a mass transit system 7 months ago to a new job , I usually drive only 8 miles round-trip per day. My car seems to run normally, though, even on longer trips.
