Can You Smog a Car with Check Engine Light On?
The short answer is no, you cannot smog a car with the check engine light on. California’s smog test requires that all emission control systems be working properly, and a check engine light indicates that there is a problem with one or more of these systems.
Why Can’t You Smog a Car with Check Engine Light On?
California’s smog test is designed to measure the amount of pollutants emitted by a vehicle. These pollutants include hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx), and they are all harmful to human health and the environment.
Emission control systems are designed to reduce the amount of these pollutants emitted by a vehicle. These systems include the catalytic converter, the oxygen sensor, and the exhaust gas recirculation (EGR) system. When one of these systems is not working properly, it can cause the vehicle to emit more pollutants than it should.
A check engine light indicates that there is a problem with one or more of these emission control systems. This means that the vehicle is not operating as efficiently as it should be, and it is likely to be emitting more pollutants than it should.
What Should You Do if Your Check Engine Light Is On?
If your check engine light is on, you should have your vehicle inspected by a qualified mechanic as soon as possible. The mechanic will be able to diagnose the problem and make the necessary repairs.
Once the repairs have been made, you can then smog your vehicle.
Can You Drive a Car with Check Engine Light On?
