Can My Car Pass Emissions with Check Engine Light On?

Introduction

The check engine light is one of the most dreaded sights for any car owner. It can be a sign of a minor problem, or it can indicate a major repair is needed. If your check engine light is on, you may be wondering if your car will still pass emissions. The answer to this question depends on a few factors, including the severity of the problem and the type of emissions test your car is required to pass.

What Does the Check Engine Light Mean?

The check engine light is an indicator that there is a problem with your car’s emissions control system. This system is responsible for reducing the amount of pollutants that your car releases into the atmosphere. When the check engine light is on, it means that the system has detected a problem that could be causing your car to emit more pollutants than allowed by law.

Can I Pass Emissions with Check Engine Light On?

Whether or not you can pass emissions with the check engine light on depends on two factors:

1. The severity of the problem: Some problems with the emissions control system are more serious than others. If the problem is minor, you may still be able to pass emissions even with the check engine light on. However, if the problem is more serious, you will likely need to repair it before your car will pass emissions.
2. The type of emissions test: There are two types of emissions tests: tailpipe tests and evaporative emissions tests. Tailpipe tests measure the pollutants that are coming out of your car’s exhaust pipe. Evaporative emissions tests measure the pollutants that are leaking from your car’s fuel system and other components. If your car is required to pass a tailpipe test, you will likely need to repair the problem before your car will pass emissions. However, if your car is only required to pass an evaporative emissions test, you may still be able to pass even with the check engine light on.

What Should I Do If My Check Engine Light Is On?

If your check engine light is on, the first step is to have the problem diagnosed by a qualified mechanic. The mechanic will be able to determine the cause of the problem and recommend the best course of action. If the problem is minor, you may be able to repair it yourself. However, if the problem is more serious, you will likely need to have it repaired by a mechanic.

Conclusion

Whether or not you can pass emissions with the check engine light on depends on the severity of the problem and the type of emissions test your car is required to pass. If you are unsure whether or not your car will pass emissions, it is best to have the problem diagnosed by a qualified mechanic.
