Other than that, the TSRM details all of the troubleshooting steps you need to accurately diagnose any problem (this one included).

hi mate, I need your help again. Today I found my check engine will on if I drive over 140Km/h, but if I shut it down and restart the engine, the light will go away, I think might be a false o2 sensor. Anyway I try to diagnostic what the problem really was, but the weird thing happen.

engine light flash once, after one second, it keeps flash 4 times quickly, after one second, it flash two times more quickly as well, then go back to beginning.

I looked up the table and I couldn't find any condition of 2,


do you have any ideas what that was? I am very appreciated.
