I said that was really bizarre as I had not had any trouble with the car before. Then, they said the check engine light was on, they couldn't get the OBD-II port to work, and I'd have to come back later for a full service appointment. I took the car and immediately found out a bunch more stuff was not working.

So, I found:

This FAQ is dedicated to new owners of the second generation Civic Hybrid who often have questions concerning their new car. It is also likely that existing owners may find a few informative bits in it as well. ;)


As before, I invite existing HCH-II owners to submit any additional tips/info that may be of help to the community.

Now I've decided to buy a grid charger for my '05 Civic Hybrid.

I've narrowed it down to either a Hybrid Automotive or a MAXX VOLTS.
They both appear to have many features in common, but I'm not sure exactly which features are best. I don't want to go cutting into wiring, or have to send anything back to the mfr.

From experience, can anyone weigh in and tell me which one is best?]]> 4 Question please: on my 2003 Insight, Wed, 15 Feb 2017 17:22:52 +0000 http://www.cleanmpg.com/community/index.php?threads/54012/ http://www.cleanmpg.com/community/index.php?threads/54012/ invalid@example.com (billy) billy 06 Civic Hybrid PCV Valve Replacement Sun, 23 Oct 2016 02:20:50 +0000 http://www.cleanmpg.com/community/index.php?threads/53771/ http://www.cleanmpg.com/community/index.php?threads/53771/ invalid@example.com (Mendel Leisk) Mendel Leisk
I'd done an earlier, exploratory attempt, found I could "reach" the PCV Valve from below, with the engine splash shield front end lowered, more easily with loosening of the frontmost splash shield and removal of a bracket attached to u/s of intake manifold: could actually get a 17 mm closed-end crescent wrench on it. But not a ratchet and deep socket, the latter banging into the adjacent intake manifold, groan...

Situation: Vehicle has 122,000 km. Purchased new in the US in May 2008. Had a $10k USD accident in 2012 (low speed side-swipe, two doors and rear quarter panel), however the repairs have held up wonderfully and the car is otherwise in really good condition. Legally imported into Canada in June 2012, Honda factory warranties transferred to Honda Canada and letter from Honda Canada obtained.

Is this correct?
Am I looking for relays, resistors, temperature sensor(s), voltage controller, current controller, pwm controller?

I assumed this is for heat dissipation from the electronics behind it, as the seatback does fit in the slots which hold it in place.
Non-hybrid models don't have this wider gap.
Can someone look at theirs and confirm this wider gap is normal? I'd never noticed it before until I put the seat back in.
