Hi there my 2010 civic was doing the same problem I replaced the ECM still had the same results as you I work in the Nissan dealership shop next to a Honda shop they have never seen this code in a Honda so we started eliminating things checking all the ground wires then pull the spark plugs and found that my spark plugs had burnt down to twice the gap that they was supposed to be I replaced the plugs fix the problem must have been putting a lot of strain on the coils causing the e c u to go into limp mode so your problem is probably your spark plugs are good be your coil on plugs
GuruWM5V6, I can't thank you enough for the recommendation to change the spark plugs. I had been looking for some online help for a few weeks for a similar issue I was having with my 2007 Honda Civic Hybrid. This car has 185k miles. I've never had an issue with this care, but over the past month, whenever I would quickly accelerate past 3,500RPM, the gas pedal would stop responding, the RPM temporarily rose to 4,000RPM, and then the RPM would fall back to idle and the car would roll to a stop. If I put the car in park and then back into drive, the car would be in limp mode and go no faster than 10mph. If I shut the car off, it would work normal again unless I again crossed 3,500RPM. I thought I had a transmission slipping. The check engine light came on with the error code P0606 (ECM). I took it to a Honda dealership who after a $125 diagnostic fee just told me to replace the computer for $1600. The answer was basically "well, it's a computer problem, there is nothing you can do except try to replace the computer". I decided to hold off. I found this message board and the mention about bad spark plugs sending some kind of shut down to the computer. I'll admit that I purchased the car with 40k miles and never changed the spark plugs, so they were definitely needing replaced either way at 185k miles. I've never had any codes from the computer suggesting misfires or symptoms of bad plugs except it being a little jerky during initial acceleration. Anyway, I replaced the 8 spark plugs myself for about $70. I'm now 2 weeks after replacement, I've challenged the acceleration up to 5,000RPM multiple times, and I can no longer reproduce the "computer failure". Thanks for saving me some money and headaches! I'm curious to hear if anyone else has the same problem. I really struggled to find an answer online.
tenho o mesmo problema no meu civic 2008 ja foi substuiudo o modulo eo codigo p0606 voltou depois de 1 mes
I replaced the spark plugs on my 08 civic and used the cheaper plugs bought online ( looked like originals ). went through the same situation as GuruK 831p except I replaced computer and same problem happened , so I replaced all the spark plugs to honda original plugs and has been fine since. The online plugs lasted no time, electrode was burnt away ,never got 15k out of plugs. I would of never thought that a 606 code would be thrown because of a spark plug issue. Check or replace plugs and buy from honda
