Check Engine Light After Car Wash
What Causes the Check Engine Light to Come On After a Car Wash?
There are a few possible reasons why the check engine light might come on after a car wash.
- Water getting into the engine: If water gets into the engine, it can cause the engine to misfire, which can trigger the check engine light. This is especially likely if the car wash uses high-pressure water.
- Electrical problems: The car wash’s water can also cause electrical problems, which can also trigger the check engine light. This is especially likely if the car has any exposed wires or connectors.
- Loose gas cap: If the gas cap is not tightened properly, it can allow water to get into the fuel tank, which can cause the check engine light to come on.
What to Do If the Check Engine Light Comes On After a Car Wash
If the check engine light comes on after a car wash, it is important to take the car to a mechanic as soon as possible to have it diagnosed. The mechanic will be able to determine the cause of the problem and fix it.
In the meantime, there are a few things you can do to try to fix the problem yourself.
- Check the gas cap: Make sure the gas cap is tightened properly.
- Dry the engine: If possible, try to dry the engine with a towel or a hair dryer. Be careful not to get any water on the electrical components.
- Disconnect the battery: Disconnecting the battery can reset the check engine light. To do this, disconnect the negative terminal of the battery for about 10 minutes and then reconnect it.
If none of these solutions work, it is important to take the car to a mechanic to have it diagnosed.
