What does the Service Power Steering Warning Light Look Like?

The Service Power Steering Warning Light is typically represented by an illuminated icon of a steering wheel on your vehicle’s dashboard. This visual indicator is designed to catch your attention and signal potential issues with the power steering system. The steering wheel icon is distinctive, making it easily recognizable among other dashboard symbols.

Here is what the power steering warning light looks like.

What Causes the Service Power Steering Light?

Low power steering fluid, power steering pump malfunctions, faulty steering gear, damaged PS hoses, and electrical malfunctions can contribute to the service steering light. There can be a few additional factors as well. Let us explain these factors a wee bit. 

Low Power Steering Fluid

If you notice the Service Power Steering Light, it could be due to insufficient power steering fluid. Low fluid levels may result from leaks or gradual evaporation. So, add power steering fluid if needed or fix the leaks to get rid of the power steering warning light.

Power Steering Pump Malfunction

A failing power steering pump can lead to the illumination of the power steering warning light. Issues such as a worn-out pump or a malfunctioning pressure control valve may be the culprits. Read our guide on “Can you rebuild a power steering pump” for more details. 

Faulty Steering Gear/Rack

Problems with the steering gear or rack, such as leaks or internal damage, can cause the Service Power Steering Light to activate.

Damaged Power Steering Hoses

Cracked or damaged power steering hoses may lead to fluid leaks, triggering the warning light. We recommend regular inspection to identify and address power steering hose-related issues promptly.

Electrical Malfunctions

Electronic components, sensors, or wiring related to the power steering system may develop faults, causing the Service Power Steering Light to illuminate.

Belt Issues

A loose or damaged serpentine belt that connects the power steering pump to the engine can result in reduced power steering functionality and activate the warning light.

Steering Angle Sensor Problems

Modern vehicles with electronic power steering systems may experience issues with the steering angle sensor, leading to the activation of the Service Power Steering Light.

What to do If the Service Power Steering Warning Light Appears?

If the Service Power Steering Warning Light appears, check the power steering fluid levels to ensure they are adequate. If power steering fluid levels are low, top up the fluid with the recommended type.

However, if you notice persistent issues or if fluid levels are normal, we urge you to consult a professional mechanic as soon as possible. Ignoring the Service Power Steering warning light can lead to potential steering problems or even a loss of power steering ability of your vehicle affecting your vehicle’s safety and performance. The repair cost also can be significant.

Is it Safe to Drive with the Service Power Steering Light?

Although you can drive with the Service Power Steering warning light, it is not something we recommend. We say this because this warning light indicates a potential issue with your power steering system, which can compromise your ability to steer the vehicle easily.

If you continue to drive with the Service Power Steering light, it may increase steering effort, making it unsafe, especially in emergency situations. It’s advised to address the problem promptly by having a professional mechanic inspect and repair the power steering system if the warning light doesn’t go off when you top up the power steering fluid. 

This ensures your safety on the road and prevents further damage to the vehicle’s steering components. Your prompt attention to the Service Power Steering Light is crucial for a secure driving experience. Read our guide on “Can you drive without power steering” for more info.
