  1. P0420 and options

    Honda Insight Forum 1st-Gen Discussion
    So, I'm getting the dreaded P0420 code on my 2001 (M/T) Insight and have been getting noticeably lower mileage for the past few months. Wanted to know what my options are. I'm approaching 260K miles, and am not really aware of much about the car's previous life (don't have the previous owner's...
  2. Insight G2 a catalytic converter theft target?

    Honda Insight Forum 2nd-Gen Discussion
    Hello everyone! Most news articles on catalytic converter theft in the UK are about Toyota Prius, Honda Jazz, and Honda Accord. There’s literally no mention of Honda Insight being a target. Do you think this is because there are fewer Insights out there compared to Jazz, or is it because...

    I've got a 2006 Insight with 217,000 miles on it. After a P2000 error code, I replaced the secondary catalytic converter a couple of years ago at around 180k miles. Two years later, this same catalytic converter is failing again with the same error code. (I'll note that I had the software...

  8. Catalytic converter source

    Honda Insight Forum 1st-Gen Discussion
    Anyone knows whether a different then OEM catalytic converter can be used on a European insight 1 (only 1 catalytic converter) and if so, if it's a drop in replacement? Mine is throwing the P420 code (especially in humid conditions). I suspect the converter and not the O2 sensor because the...

My MPG went up somewhat after that back into the upper 40s and...
