Check Engine Light Came On After Car Wash
What Does It Mean?
The check engine light is a warning light that indicates a problem with your car’s engine or emissions system. When the light comes on, it means that your car’s computer has detected a problem and has stored a trouble code in its memory.
There are many possible causes for the check engine light to come on, including:
- Loose gas cap
- Faulty oxygen sensor
- Spark plug problems
- Ignition coil problems
- Mass airflow sensor problems
- Throttle position sensor problems
- Catalytic converter problems
- Exhaust system problems
If the check engine light comes on after you wash your car, it is possible that water has gotten into the engine or emissions system and caused a problem. This is especially likely if you washed your car with a high-pressure hose.
What Should You Do?
If the check engine light comes on after you wash your car, you should:
- Stop driving your car immediately.
- Check the gas cap to make sure it is tight.
- Call a mechanic and schedule an appointment for them to diagnose the problem.
It is important to have the problem diagnosed and repaired as soon as possible to prevent further damage to your car.
How Can You Prevent It From Happening Again?
There are a few things you can do to help prevent the check engine light from coming on after you wash your car:
- Avoid using a high-pressure hose to wash your car.
- If you do use a high-pressure hose, be careful not to spray water directly into the engine or emissions system.
- Dry your car thoroughly after washing it.
By following these tips, you can help keep your car running smoothly and prevent the check engine light from coming on.
