The reasons for this message vary, but common culprits include:
* Low power steering fluid: This is the most common and easiest to fix. Check the fluid level in the power steering reservoir (usually a small clear or translucent tank). If it's low, add the correct type of power steering fluid (consult your owner's manual). However, if the level is low and you don't know why, there's likely a leak somewhere that needs to be addressed.
* Power steering pump failure: The pump is what circulates the fluid. A failing pump can lead to low pressure and the warning light. This requires replacement.
* Power steering pressure sensor malfunction: This sensor monitors the system's pressure and can cause the warning light even if the pump itself is functioning. It might need replacement or just cleaning.
* Faulty wiring or connector: Problems with the wiring or connectors to the power steering system can also trigger the warning light.
* Internal leak within the power steering system: A leak within the power steering rack or hoses will also cause low fluid and ultimately affect the power steering.
What to do if the warning light comes on:
1. Pull over safely as soon as possible. Steering will be significantly more difficult, especially at low speeds.
2. Check the power steering fluid level.
3. If the fluid is low, add fluid (but only if you are sure you know why it is low; otherwise do not add fluid). Don't overfill.
4. Have the vehicle inspected by a qualified mechanic immediately. Don't continue driving for extended periods with this warning light on, as damage to the power steering system can increase the repair cost.
Ignoring the warning light could lead to complete power steering failure, making the vehicle extremely difficult and dangerous to control. Professional diagnosis is essential to identify the root cause and ensure a safe repair.
