2007 Toyota Tundra check engine light

DTC’s P0418, P0419, P2437, all have to do with the secondary air injection system.

DTC P0300 is for random misfires detected.

The Vehicle Stability Control light is on because it won’t function as long as the Check Engine light is on.

The DTC code P0300 could be caused by the secondary air injection problem.
