#112 of 116 the secondary cat converter and drive cycle info
May 05, 2012 (7:56 am)
The dealer told me $1100 for the secondary (rear) catalytic converter and 3000 for the IMA battery. I bought the rear catalytic converter on line at RockAuto.com for 169.00 for the cat plus shipping plus I got a gasket I wasn't sure I needed for 3.90... just in case. I attempted to put in myself but if you don't have it up in the air (higher than jacks) it's nearly impossible especially for someone my size! After a couple of busted knuckles and many choice words, I called a muffler place and told them I had the parts... they put it on for $100.00 and reset the check engine light. Total was under $300.00. Oddly enough, my IMA light hasn't come back on either and I'm getting slightly better gas mileage. The better mileage makes some sense but my IMA battery light staying off does not and I can only hope it stays off! Also, I read something about the drive cycle on line and it seems to be true. The actual drive cycle is a wide variety of speeds and such - some highway, some in town stop and go. But, this may be useful... IF you put the key in and the engine is cold and turn it but DON'T start the engine you'll see the check engine light come on steady for about 10 seconds. IF it goes off and blinks 5 times - that means the drive cycle in NOT completed. It it goes off after the initial 10 seconds and doesn't blink - that means the drive cycle IS complete. It took about 50 miles... I drove it home from the muffler shop about 30 miles and the next morning I checked and got the 5 blinks. The I drove to work about 20 miles and check it many hours later after it cooled and it did NOT blink the 5 times. I took it straight to the emissions place (another 20 miles) and it passed. I hope this helps!

Well, a few days later my IMA light came back on then went off again. Likewise with the check engine light. But, I passed inspection as I mentioned above! I going to trade the PoS in before the next inspection and I think I'll try a Ford. They get as good or better mileage than this Civic hybrid.... and Ford didn't take a bailout from what'shisname in DC! Good luck to you all!

I am having a similar problem and want to get the CC replaced and observe before I spend the 3k for the IMA batt. Have you had any problems since this posting? Thanks

Unrelated to cc, air conditioning went out last fall. IMA battery light has been on a few months, but given the age of my vehicle and milage, I don't plan on replacing the Hybrid batteries. On a positive note, Honda did finally reimburse me for the cost of replacing the cc. This was after a couple of nasty letters to Honda and filing an offical complaint with the BBB. I understand there is also a class action lawsuit against Honda for this very problem, as a lot of Civic Hybrid owners have had the same problem with the cc.
Hope this helps,
#116 of 116 2004 HCH - IMA & Catalytic Converter Failures
Jan 10, 2013 (8:20 am)
I bought a 2004 HCH for my son about a year and a half ago. The check engine light has been off and on along with the IMA light. We had the recent update done by the local dealership as well which turned off all the lights but within a week they were back on. He drove the car to NY last weekend and on his way home the car started knocking badly then died in the middle of Manhatten traffic. After the cost of a tow bill to get it off the street ($70), a plane ticket home ($250) and the cost to haul the car back to TN ($750), I get an estimate on repairs from the local dealer to the tune of $4956 - PRICELESS!
The IMA battery needs to be replace as well as the catalytic converters. Though the car will actually start now and we were able to drive it home (5 miles away), I am at a total loss on what to do. With 194,000 miles on it, I'm not sure it's worth investing another $5K in!
I've been told two different things as far as options: Per the dealer, everything has to be replaced and done at once. Another mechanic has told me to just fix the CCs and not the hybrid batter and run it as a gas vehicle. I've done some research and have found some comments that these cars do not have an alternator and without the hybrid battery, the main battery won't charge.
Maybe I should just consider it a loss and try to sell it for parts. Any thoughts or similar experiences?
