* The check engine light indicates a problem: The light is triggered by a malfunction in the car's emissions system. This could be anything from a faulty oxygen sensor to a clogged catalytic converter.
* Emissions testing checks for specific issues: During emissions testing, technicians check for specific pollutants in your car's exhaust. These pollutants are directly related to the components the check engine light is signaling a problem with.
* The test will likely fail: The test will most likely fail because your car's emissions are not within the acceptable range.
However, there are some rare exceptions:
* The problem is minor: Sometimes, the check engine light might be triggered by a minor issue that doesn't directly affect emissions, like a loose gas cap. This is unlikely, but possible.
* The test isn't thorough: In some areas, emissions tests are less stringent and may not catch the issue causing the check engine light. This is also uncommon.
The best course of action:
* Get the problem diagnosed: Take your car to a mechanic to diagnose the issue causing the check engine light. They can use a code reader to identify the specific problem and recommend a solution.
* Fix the problem: Repair the issue to ensure your car passes emissions testing and runs properly.
Remember: Driving with a check engine light on can damage your car and contribute to pollution. It's always best to address the issue as soon as possible.
