I’m writing this as I sit in the service department of my Honda Dealership. My car (LINK: http://www.thetruthaboutcars.com/piston-slap-the-annoying-lazy-civic/) was due for a service, and I had enough: I was going to get results from the dealership regarding my lazy drive by wire system in my 2007 Civic. Long and short, they test drove my car against a new 2009 Civic, and (finally) found that there is definitely something wrong with my car.

So they tried to see what they can swap (from the 2009 model) to rectify the problem, but the biggest step of all is that they have admitted there is a problem. This was a major victory for me.

They contacted the Honda techs, and found out what (if any) hardware changes occurred between the 2007 and 2009 model. They started swapping sensors, driving the car, and so on. Bottom line, they replaced the O2 sensor, which was throwing readings all over the place. They also reset the engine computer. It’s been 5 days now, and I have not yet experienced any of the issues that I had been complaining about.

Sajeev replies:

So let me get this straight: you had to waste time with several dealership visits while a faulty O2 sensor threw codes all this time? Codes that AutoZone employees find blindfolded with their fingers duct taped together?

And instead of checking for codes (or testing the engine computer if it didn’t generate anything) they swapped sensors all willy-nilly like? Talk about a needle in a haystack method of diagnosis. But I’m a firm believer in the mantra of “there’s always more to this story.”

Perhaps the O2 sensors only threw codes the last time you visited the shop. Still, this diagnostic tree sounds like a cactus: full of costly pricks. So much for the Civic being annoying and lazy, that statement fits Honda’s factory-backed service department. Like, wow.

    While the O2 sensor maybe only throwing codes at a particular moment, the engine computer should be logging these. Most of the time, a faulty 02 sensor will throw a code and a CEL light will show on the dash. I just don't think that the codes would go away unless they were cleared. Restarting the car doesn't clear codes. I would find a different service department and fast.

      Correct: OBD-II systems log stuff (like O2 faults) and keep it for anyone with an advanced scan tool (not the free one at AutoZone) to see. Question is, did they understand it?

    A co-worker of mine has been complaining about the poor fuel mileage (19-21mpg) that he's been getting from his 4-month-old 4-cyl/5 auto Accord Coupe - it's not throwing any CEL's, and runs fine. He does not drive the car hard at all. When I was considering the same car last year, my research on the 'net gave me pause; several complaints about poor gas mileage from Honda fours (even the Fit's 1.5l) - but I figured that people were just beating the crap out of them; now I'm wondering about Honda's veracity regarding their ECM and sensors.

  • ChristianWimmer I don’t want this autonomous driving garbage technology in any car.My main fear is this. Once this technology is perfected, freedom-hating eco hysterical governments (crap hole Germany, UK and the European Union in general) will attempt to ban private car ownership because “you don’t need to own a car anymore since the car can come to you, drop you off and then proceed to service the next customer”... no thanks. Having your own car is FREEDOM.Go away, autonomous driving. I also enjoy the act of driving a car. I want to drive, not be driven.
  • Mike-NB2 The solution is obvious here. Everyone should be raised in an Irish Catholic family and then all it takes is a sideways glance from mom and you're atoning for that sin for the rest of your life. My mother has been dead for decades and I still want to apologize to her. Catholic guilt is a real thing. 😁
  • Wjtinfwb A good car. I don't find Accord's as appealing as they were a decade or two ago, not that they've gotten worse, but the competition has gotten better. It would be my choice if I had to pay for it myself and maintain it for 10 years and 150k miles. They'd be very reliable and no doubt inexpensive miles, but probably a pretty boring 10 years.
  • Lou_BC "augmented reality" Isn't that a mamoplasty?
  • Lou_BC Nice to see car companies still building cars. If I ever desired a new car, a Camry and Accord would be on the list if not the only 2 cars on the list. Who else makes a decent 4 door sedan?
