How can I help my vehicle pass a Smog Check?
Performing regular and proper maintenance according to your owner's manual and not tampering with the emissions-control equipment will help improve your vehicle's chances of passing a Smog Check. If the "Check Engine" light comes on, take your vehicle to a licensed repair station as soon as you can to have the problem diagnosed-do not wait for the vehicle's next scheduled Smog Check. A blinking or flashing light indicates a malfunction that should be addressed immediately to avoid serious damage to the engine or emission-control systems. Check your owner's manual for repairs that may be covered under your vehicle manufacturer's emissions warranty.
