Code 43 is often due to running too rich or could also be a variety of fuel system related issues… Clogged fuel filter, bad O2 sensor/wiring defects, valve adjustment, dirty air filter, etc. Change the filters if dirty and perhaps do a valve adjustment if due. Check O2 sensor readings/check for wiring damage before moving on to more expensive tests/repairs.

Hi simple conclusion it is now only fit to make beer cans. As it has done it's job exceeded the design life that honda intended of 8 years or 100 k miles. So is now a scrapper.
A check engine light tells you drive slowly to a dealer or mechanic.
- Check engine light, open door light, and batterie light all came on and won't go off? 2000 Honda Odyssey I already had the altinator replaced it a month old. The batterie almost a year old. Would the belt need be changed or something else?
- Does a broken muffler/exhaust cause a check engine light to turn on on a 97 Honda civic? Recently my muffler broke and snapped off my 97 honda civic and a day later my check engine turned on, i just got the muffler welded back on. Was the broken muffler the cause of the check engine light to turn on? Will it turn off now that i got the muffler welded back on?
- Check engine light turns on for a few days and then turns off for weeks/months? Code P0420 on a 2004 Honda Civic Hybrid? Over the last year my check engine light has come on about 3 or 4 times for a few days at a time and then turns off again for a very long period of time. I know the code means my catalytic converter is below threshold but why would it turn off? Could it be something else? Should I look into replacing it or wait it out? Any advice is appreciated!
- Bought a 2006 Honda Civic ex about a month ago, the check engine light came on and it was throwing code p0133 o2 sensor slow response? Bank 1 sensor 1. Now I checked again and it's a P0171 code as we'll System Too Lean Bank 1 . My friend looked at it and said it's my oxygen sensor. Could that be the reason, and is that way it threw the other code as well? The car runs pretty good, does guzzle has a little.
