Many car owners have experienced the frustration of their check engine light coming on after driving through heavy rain. But, is there a direct correlation between heavy rainfall and the check engine light? Let’s find out.
Why does the check engine light come on when it rains?
Driving through water can lead to a check engine light coming on. Water entering the engine can cause various issues, such as misfires and damage to electrical components.
When rainwater enters critical parts of the car, it can damage the engine and other essential components beyond one’s control. For instance, if water enters the engine inlet air tubing, it may result in permanent damage, making the car unstartable or slower than usual.
In some cases, water can get into electrical components or sensitive parts of the car, leading to electrical issues or corrosion. This can trigger the check engine light as a warning sign of potential damage.
Preventing check engine light during heavy rain
While it may not be possible to completely prevent the check engine light from coming on during heavy rain, there are a few precautions you can take to minimize the risk:
- Inspect and maintain your vehicle regularly to ensure all seals and connections are intact.
- Avoid driving through deep standing water, as it can increase the chances of water entering critical parts of the car.
- Keep your ignition system well-maintained to prevent misfires caused by water damage.
- If your check engine light does come on, it’s important to have it checked by a mechanic to diagnose any potential issues.
What to do if the check engine light comes on after driving through heavy rain
