Will low power steering fluid cause check engine light? This is a common question among vehicle owners who notice their check engine light illuminated on the dashboard. Understanding the relationship between low power steering fluid and the check engine light is crucial for diagnosing and resolving potential issues with your vehicle.
Power steering fluid plays a vital role in the power steering system of your car. It helps to reduce the effort required to turn the steering wheel, making driving more comfortable and easier. However, when the power steering fluid level drops below the recommended level, it can lead to various problems, including the activation of the check engine light.
How does low power steering fluid lead to the check engine light?
When the power steering fluid level is low, it can cause the power steering pump to work harder than usual. This increased workload can lead to overheating and eventually damage the pump. The engine control unit (ECU) detects this abnormal behavior and triggers the check engine light as a warning sign.
Moreover, low power steering fluid can also cause air to enter the system. Air in the power steering fluid can disrupt the smooth operation of the system, leading to poor steering performance and potentially triggering the check engine light.
What should you do if your check engine light is on due to low power steering fluid?
If you suspect that your check engine light is on because of low power steering fluid, follow these steps:
1. Check the power steering fluid level: Open the hood of your car and locate the power steering fluid reservoir. Check the fluid level and color. If it is low or appears to be dark and dirty, it may be time to top it up or replace it.
2. Top up or replace the fluid: If the fluid is low, add the appropriate type of power steering fluid to the reservoir until it reaches the recommended level. If the fluid is dirty or has a burnt smell, it is best to replace it entirely.
3. Check for leaks: Inspect the power steering system for any signs of leaks. Leaks can cause the fluid level to drop and may require repairs to the system.
4. Reset the check engine light: Once you have topped up or replaced the power steering fluid, reset the check engine light using a scan tool or by following the manufacturer’s instructions.
Conclusion
In conclusion, low power steering fluid can indeed cause the check engine light to illuminate on your vehicle. By addressing the issue promptly and maintaining the appropriate fluid level, you can prevent potential damage to the power steering system and ensure safe and comfortable driving. Always consult your vehicle’s manual for specific instructions on maintaining the power steering fluid level and addressing any related issues.
