cwingert Report post Posted July 25, 2011 Thanks BB, I found that information already. I was more interested in hearing what caused the problem. Disconnected hose? Bad valve? Pump? Thanks, Chris Quote Share this post Link to post Share on other sites More sharing options...
BLACKBULL Report post Posted July 25, 2011 cwingert.....can you give more details?? Under what conditions is this occurring? How often?? What happens (i.e car shuts down, etc) With only the information provided I would suggest you have your o2 sensors checked.

cwingert Report post Posted July 25, 2011 Hi BB, So I clear the codes on a run and then it appears the second start after that (according to that table its only read on start up). I don't think its the O2 sensors, because it happens on both banks. It must be some that there is just one of (like the pump) or the pipes. The car was recently services by Lambo of Beverly Hills maybe they forgot to hook something back up. Are you a Lambo mechanic? I'll bring it in for service today.

BLACKBULL Report post Posted July 25, 2011 cwingert I am NOT a lambo mechanic; don't want to misrepresent myself. My experience & knowledge comes from my project 350Z TT . I have the code reader and monitor my set-up regularly. I m assume you have a factory set-up. Have you had rough idle???.....what about hesitation?? If so does it occur when engine is hot?????......or cold???? What kind of gas used.. Just throwing out a few questions as food for thought.

cwingert Report post Posted August 6, 2011 Turns out that a line from the secondary air injection system was disconnected. Pretty sure it happened at the full service at BH Lambo. Symbolic Motors fixed it for me. Thanks for your input BB! Quote Share this post Link to post Share on other sites More sharing options...

Hi, I have the same code on my 06 6speed manual (P0492) just on today and I was wondering if you have any idea where is that secondary air system location? I want to make sure if it was unplugged from last service. Thank you Quote Share this post Link to post Share on other sites More sharing options...
