Engine light 2006 pontiac g6(reset)

First be sure that its the engine light and not the "service" light. the service light will usually illuminate if its time for an oil change. if its the service light ur owners manual should tell u how to reset it. if its ur engine light then try disconnecting ur positive battery cable for 1 minute. that should reset ur ecm and get rid of the engine light. if the engine light comes back on then have a diagnostic scan done to determine whats causing it.

Take the negative battery terminal off the battery for one minute. Then replace the Battery terminal carefully, always use caution when taking off the positive battery terminal, and make sure the metal wrench you are using does not touch a metal part on the car. Always take off the negative battery terminal for one minute, then replace the negative battery terminal. This should clear your fault code and automatically reset your check engine light. If your check engine light come's back on. Your vehicle has another fault code that need's servicing on your vehicle. Sincerely Crystopper.

After replacing the gas cap .. unscrew the terminal from the battery for a minute. The easiest one is the one away from air intake from the air filter box. Just set it aside gently. Of course you need to reset your clock and your radio stations after screwing the wire back on.
