Contrary to public belief, the Check Engine light being illuminated anytime
during the smog inspection is automatically a smog failure. Vehicle
manufacturers have placed the Check Engine light inside the passenger
compartment to inform the driver there has been or is an engine or drive
train malfunction. Very often you may not notice an engine problem, but this
is only because your engine's computer is operating under pre-programmed
information rather then of real-time. In other words the problem still
exists but your engine learns to live with it. In this particular case you'll absolutely need to fix your Toyota Tundra's speed control problem and make sure the check engine light turns off before having your truck retested.
