Hi, I own a 2006 Insight with roughly 70,000 miles on it. I often lurk on the board and frankly my Honda has given me little trouble for the two years I've owned it. I did replace the O2 sensor last month after the CEL came on. The code was cleared and things were running fine. Shortly thereafter the CEL came back on and this time it was the fuel cap. Once I unscrewed it, I noticed the retaining cord had broken and was twisted into the threads of the cap, presumably causing the error code. I went home and removed the negative battery cable, let it sit for 15-20 minutes and reattached it. The CEL did not come back on and again the car drove well.
Then the other day I received a notice in the mail that my registration was coming due. In Oregon we have to pass an emissions test before we can renew our tags for another two years. I went to DEQ and when they plugged into the OBDii, the car failed to download any information. They tried twice..still nothing. I was in a hurry to get to work but they said it may well just be a fuse. I drove less than a block when the Insight went into auto stop mode and suddenly it began chiming at me. It's never done that in the two years I've owned it. Also, the reminder chime that tells you the lights are on and the chime for leaving the key in the ignition after turning the car off and opening the door aren't working.
Mechanically the car seems to drive as usual, although without power to the OBDii, the CEL isn't on. I pulled the negative battery cable again tonight, and my boyfriend and I cheched any obvious fuses (all that we checked were fine) but the same symptoms remain. I was going to go to Autozone in the morning to see if maybe they could get a reading. If not, I think it's back to the dealership to try and figure out what happened. I'm wondering if the tech at DEQ somehow short circuited the PCM when he tried testing it? What are your thoughts? I plan on calling DEQ on Tuesday when they are open and try and find out what they did. Just seems odd that all these things started happening minutes after they said they couldn't read anything when a month ago, codes were pulled by both the dealership and Autozone. Anyhow, thank you guys for taking the time to read this and I appreciate any advice.
That was one of the first things Dave and I checked. That fuse and the others we pulled (based on doing a forum search for beeping auto stop) appeared completely intact. I'll pull it again in the morning and look again. Frankly, I would love for it to just be a fuse and a 5-10 dollar fix rather thsn a new ECM that would be way more expensive. Thanks again guys, I'll keep you posted on what I find.
Bad news..Dave and I changed out the fuses and still nothing. Any other ideas?
This isn't particularly helpful but you (read: Dave, lol) really need to buy a code scanner. They're cheap enough now (online and brick&mortar) that anybody who intends to "DIY" their repairs has to have one.
I agree with you about the scanner but my last car was an '89 Chevy Cavalier Z-24 that didn't use OBDii. Also, up until a month ago, the Insight hadn't given me a single problem. I will be buying one at some point.
Incidentally, I went to Honda this afternoon and they couldn't get any sort of power from it either. I have an appointment to drop it off Friday. Thanks for all the ideas. I really appreciate it.
