The car didn't lose actual power. I took it to my mechanic and the PCM code came up and said update possibly available from Honda. so he said I needed to take it in to the dealer. They did the update and the next afternoon it did the same thing again and the check engine light came back on. I just would like some possible answers before i take it back so I am more informed and don't get something I actually don't need.

Thank you for your help

honestly ive never heard of a code stating you need an update.... get it scanned at your local parts store, and get us the actual code... we can help from there.

Hi,

First, we need to determine what code was actually set. Here is a link that shows how it's done:

I realize most people don't have a scanner. However, most parts stores will do it free of charge. So try to have that done and let me know what the code is.

Next, there are two fuses I want you to check. They are both in the under dash fuse box. Now, I don't suspect the fuses are bad, but I need you to make sure they are tight and there is no corrosion where they plug in.

If you look at the attached picture, it shows the two fuses I am referring to. Check those and in addition to looking at the fuses, make sure power is equal on each side of the fuse. Something could be making intermittent connections.
