How much to replace 2001 Honda CR/V Catalytic Converter

    Two separate Honda dealers have diagnosed a failed catalytic converter
    on my daughter's 2001 Honda CR/V. One wants $1,100 to fix it. The
    other simply says, "Thousands." The catalytic converter needs to be
    replaced. The car has 105,000 miles on it.

    Can anyone give me an authorative real world estimate of what this
    repair should cost, including if done by someone other than a dealer?

    Thanks

    Hi,
    Tried wrecking yard for a good used one? Wonder what caused it?
    There must have been warning symptoms B4 it failed.

    Thanks for the prompt response. The Check Engine light had come on.
    She brought it into the Honda dealer where she bought it to have it
    checked out.
    They said they checked it out but made no mention of a catalytic
    converter problem and also suggested she have he 100,000 mile
    servicing done. She did have it done at a cost of $400 and went on her
    merry way. Two days later the Check Engine light came on again. It was
    a few weeks before she could get back to the distant dealer. When she
    bought the car used she got a 100,000 mile warranty, which is moot
    because this failure occurred after 80,000 miles, the point at which
    even under the 100,000 warranty the CC is no longer covered.

    I somehow doubt it would be wise to buy a used CC at a junk yard not
    knowing whether it is any good. For many parts that is a prudent
    option. But not, I think, for a CC.

    Thanks for your help, though

    There are aftermarket cats that I assume would be less than an OEM
    one. Did the deal give you a parts and labor breakdown? I would go to
    an exhaust shop (Mida, Meineke, etc) and get an estimate. If would
    have to be less than the dealer, I would think.

    The dealer will replace the cat with a new OEM one, which is why you're
    quoted that figure. Aftermarket cats will be a third that.

    Before you actually get it replaced though, read this, from Honda
    ServiceNews from Oct '98:

    Before you troubleshoot an OBD II vehicle that stores DTC P0420 catalyst
    system efficiency below threshold), run these quick checks:
    1. Check for a leak in the exhaust system. If you find one, repair it,
    clear the DTC, and test-drive the vehicle.
    If the DTC doesn’t come back, return the vehicle to the customer.
    If the DTC returns, go to step 2.
    2. Connect the PGM Tester, and test-drive the vehicle while an assistant
    monitors the voltage signal from the secondary oxygen sensor (HO2S S2).
    After the catalyst reaches operating temperature, the HO2S S2 voltage
    should stay between 0.5 and 0.8 V at steady cruising speed. During
    deceleration, the voltage should be steady at 0.1 V or less.
    If the voltage readings are OK, clear the DTC, and return the vehicle to
    the customer.
    At cruising speed, if the voltage fluctuates or stays below 5 V, go to
    step 3.
    3. Measure the inlet and outlet external temperatures of the catalytic
    converter with a thermometer capable of reading up to 500°F.
    If the outlet temperature is more than 100°F hotter than the inlet
    temperature, the converter is OK; clear the DTC, and return the vehicle to
    the customer.
    If the outlet temperature is less than 100°F hotter than the inlet
    temperature, replace the converter.

    @g4g2000hsf.googlegroups.com:


    It is illegal in the United States to install used cats that have not been
    certified and labeled with a special EPA sticker.

    If the cat has the EPA sticker, it's OK.

    -----------------------------------

    The dealer probably didn't even ask whether she's ever had her valves
    adjusted. On the first generation CR-V they need to be adjusted to the
    loose side of the specs every 30,000 Miles (50,000 Km). There's a big
    fat lie in the (North American versions of the) Owner's Manual.

    An aftermarket cat will be OK, but don't bother replacing the cat if you
    haven't isolated what caused it to fail. Has her car ever stalled within
    the first five minutes of start-up? That's the other most important
    symptom of tight valves.

    Here's an older thread you could start with:

    When you quote ENGINE TROUBLE CODES, it's very helpful to give the
    actual numeric code. The 'interpretation' is often found to be meaningless.

    Hi,
    My concern is finding the cause of failure B4 replacing it. Otherwise
    new cat may go bad soon too.
