    Problems & Issues
    My 2001 CRV with 197000 miles is rattling upon start up. I checked the exhaust and its fairly tight, the heat shield on the converter is tight. I have no codes, even though check engine light is on. I had two places scan it with handheld, and my own and nothing. I had a weird chassis code a long...

  6. Why 2 catalytic converters in crv.

    Under The Hood / Performance
    What is the purpose of having 2 3-way catalytic converters in my 2010 cr-v? Only the first one, called the warm-up CAT, has O2 sensors mounted before and aft. The second CAT, called the under-floor CAT, has no O2 sensors. Obviously the shapes of the 2 CATs are different, but are 2 really...

  9. Catalytic converter replacement

    Maintenance and Service
    Hello, I have 2004 CRV and ended up replacing the cat. I got a walker OEM replacement with gasket. I got after market spring bolts. They were collared too long so I added a .25 inches worth of washers on each at the bolt head to create more gasket pressure. I have done the work and driven...

    Planning to replace the catalytic converter heat shield soon to get rid of a rattle that's developed. Already have all the parts, just looking for a free weekend. Just wondering, does the O2 sensor need to be removed in order to get the old heat shield off? Or is there a way to easily unplug...
  11. What to do about a disconnected Catalytic converter?

    Problems & Issues
    The CC got disconnected from the exhaust system (not from the engine, but the downstream pipe), and it now sounds like a motorcycle. How fast do I need to replace this? Should I remove the CC while I wait for repairs? Should I wait till after I get my belts changed (they need to be replaced) or...

  13. Loose hose near my catalytic converter.

    Problems & Issues
    So my V has been feeling sluggish and seems like there is some resistance when I press the gas. Went over to my cousin who has an obd2 scanner and code p0134 came up so I changed the 02 sensor. There was no change and the idle looks like its high. It goes to about 1.5k rpm when I turn it on and...

    Maintenance and Service
    So here's my sad story. CEL on my 2004 CRV came on, 116K. Ran codes that indicated the problem was the upstream O2 sensor. Bought a Desco sensor online. My parents recommended a guy who could do the replacement for cheap. Guy starts to work on it. Says that the bolt was really rusted and...
  15. Best catalytic converter for the money?

  16. Catalytic converter light help!

    Under The Hood / Performance
    I am trying to figure out how to shut off this light on our 1996 Honda CRV. I learned before that it is for the catalytic converter, which seems to be free and clean. I do not know if perhaps it is something that it is designed to go on after a certain time to tell you to replace it, or if it...

  20. Catalytic Converter

    Problems & Issues
    In my 2002 CRV the Catalytic Converter has gone out, my Honda Mechanic said to run premium gas through the car and it takes care of the problem since my city does not do emission testing. Then when talking to another Honda mechanic he said it doesn't matter what gas I use. They both said I do...
