Check Engine Light After Car Wash

Last Updated on April 25, 2023 by Ryan

The Check Engine Light (CEL) coming on after a car wash is usually caused by moisture getting into the electrical system. This can happen when water enters through an open window, or if the vehicle has been sitting outside during a rainstorm while being washed. To resolve this issue, dry off any wet areas with a towel and check for any exposed wires that may have gotten wet.

If this doesn’t solve the problem, it’s best to take your vehicle to a mechanic who can diagnose and repair the issue at hand. It could be anything from worn spark plugs to faulty wiring or damaged sensors; professional advice is recommended in these cases.

Driving through a car wash is one of the most convenient ways to keep your vehicle clean and looking great. However, after you finish washing your car, it’s always a good idea to check for any signs that something may be wrong with your engine. One of these signs is the dreaded “check engine” light on your dashboard.

If this light appears after a car wash, it could mean there was an issue with the water or soap getting into certain parts of the engine and causing it to malfunction. It’s important to have this checked out by a professional as soon as possible in order to avoid any further problems down the road.

Can a Car Wash Damage Your Engine?

It is possible for a car wash to damage your engine if the wrong type of cleaning products, equipment and techniques are used. For example, high-pressure washing can cause water to enter the air intake system or other areas it shouldn’t be in and cause corrosion or electrical issues. If brushes are used they may scratch paintwork or worse still scrape essential components of the vehicle leading to further problems.

To avoid any potential damage, use an automated brushless car wash, preferably one that uses soft cloths rather than hard bristles which could potentially scratch surfaces on your car and lead to rusting over time.

Why is My Engine Light Flashing After Car Wash?

The engine light can flash after a car wash for a variety of reasons. The most common cause is that water got into the engine bay, either through loose seals or through an open hood during the washing process. Other potential causes include damage to electrical components due to pressure washing or chemical residue left behind from cleaning products.

If your engine light comes on after a car wash, it’s important to take your vehicle in for service as soon as possible so that any issues can be identified and resolved before they lead to more severe problems down the road.

How Long Does It Take for a Check Engine Light to Come Back on After Erasing It?

The amount of time it takes for a check engine light to come back on after erasing it varies depending on the cause of the issue. Generally speaking, if an underlying problem has been resolved and all necessary repairs have been made, then the check engine light should stay off indefinitely. However, if there is still an unresolved issue or defect that triggered the warning in the first place, then it may reappear shortly after being reset—sometimes even as soon as you start your car again.

It’s important to remember that resetting a check engine light won’t actually fix any underlying problems with your vehicle; instead, you must identify and address any issues before they can be properly remedied.

Why is the Engine Check Light on After Auto Care?

The engine check light, also known as the “check engine” light, typically illuminates when there is an issue with the vehicle’s emissions system or other monitored systems. After auto care service such as oil changes and tire rotations, it is possible for the sensor to be disturbed which can cause the engine check light to illuminate. It might also indicate a more serious problem such as a faulty oxygen sensor, loose gas cap or failing catalytic converter.

If your car has recently had any type of maintenance done on it and you notice that your check engine light is now illuminated, have a qualified mechanic inspect your vehicle right away.

Conclusion

In conclusion, it is important to pay attention to your car’s check engine light after a car wash. It could be an indication of something bigger and more serious than just water getting into the system from the wash. Have a mechanic inspect your vehicle as soon as possible if you experience this issue in order to ensure that no further damage is done or additional repairs are needed.
