[DeTomaso] NPC Check Engine Light

[Art Stephens]

Hello guys,
I was driving my new Honda CR-Z  Hybrid thru Death Valley the other night when I came around a curve and found a rock in the middle of my lane. I wasn’t able to avoid it so I straddled it but it was too tall and banged up the bottom of my car. As soon as that happened I got a check engine light which turns out to be a Secondary HO2S Circuit Fault (sensor2), O2 sensor as near as I can figure. I can see no apparent damage to the sensor but the muffler has a big dent in it. Is the dented muffler the likely cause of the problem, increased heat due to the restriction, or does the circuit fault mean there is no signal from the sensor, or something else? I know if I take it to the dealer that they will want to replace the muffler and tail pipe for a thousand dollars and still no guarantee of solving the problem. Any thoughts?

Thanks,
Art
