catalyst efficiency below threshold,look for physical damage on the bottom of the converters. Physical damage,excessive misfire events,stuck open injectors will cause catalytic converters to go bad. If you get the code for catalyst efficiency below threshold it's pretty much a done deal for the converters,you just have to make sure you know and correct the root cause.

There has been no misfiring.. I bought it at 109K I drive a lot with my job...should I get a 2nd opinion if and when the check engine light comes on again? I've ruled out which gas station's attendant doesn't put gas cap on I posted. Was hoping for something a lot less expensive L O L Thanks for your reply!

On the advise of a male friend..I did go to Auto Zone and asked them to read the codes.....PO 705 (Honda code I think) Short in transmission 661 short circuit condition 662 Faulty transmission range switch I believe I read about a recall for trans, for this year 2000 odyssey. Emmission control system leak detected: 661 loose fuel cap 662 vapor canister saturated 663 failed vent solenoid 664 failed purge solenoid Catalyst system effenciy below threshold bank 2 661 A/F ratio concern 662 Air leak near HO2S bank 2 663 Ignition system concern 664 Faulty catalytic converter So, my question is....shouldn't the other "probable causes" be ruled out before spending $$$$$$ on something it "might" not be Thanks for any input........
