Power steering warning light on? What it means & what to do

If the power steering warning light comes on, steering assistance may be reduced or lost. The steering can feel very heavy at low speed, making parking and manoeuvres harder. AutoAid can diagnose electric or hydraulic power steering faults on site in Warrington.

Heavy steering

Assistance reduced or off — drive carefully.

Most common

Low voltage or low fluid (hydraulic systems).

Best message

Reg + postcode + light on + steering heavy?

What to do first

Drive cautiously and avoid tight turns/parking until checked.
If steering becomes suddenly very heavy, stop somewhere safe.
If it’s a hydraulic system, check for fluid leaks under the front of the car.
If you also have battery/charging warnings, book diagnosis ASAP (low voltage can disable steering).

Important: You can usually still steer the vehicle, but it may require much more effort. Don’t ignore the warning — especially if the steering changes suddenly.

Electric vs hydraulic power steering

⚡ Electric power steering (EPS)

Uses an electric motor and sensors. Very sensitive to low battery voltage and electrical faults.

💧 Hydraulic power steering

Uses a pump and fluid. Low fluid, pump issues, belt problems and leaks are common causes.

🧠 Electro-hydraulic

Some cars use an electric pump with fluid — a mix of both systems.

Common causes of a power steering warning light

🔋 Low battery voltage

EPS systems often disable assistance when voltage drops (weak battery / alternator issues).

💧 Low power steering fluid

Hydraulic leaks can cause heavy steering and noise. Check for wet patches under the front.

⚙ Pump fault (hydraulic)

A failing pump can reduce assistance, cause whining noises, or intermittently cut out.

🧷 Drive belt issue

On belt-driven pumps, a slipping or snapped belt stops pressure building.

📟 Steering angle/torque sensor

EPS needs sensor signals. Faults can trigger the light and disable assistance.

🔌 Wiring / module fault

Corrosion, water ingress or module faults can cause intermittent steering warnings.

Can I keep driving?

If steering is only slightly heavier: short careful drive may be OK — book diagnostics.
If steering suddenly goes very heavy: stop safely and get it checked.
If combined with battery light: urgent — low voltage can cause multiple systems to fail.

How AutoAid diagnoses steering faults

We scan for steering fault codes, check battery/charging voltage, inspect fluid/belts where applicable, and confirm whether the motor, pump or sensors are behaving correctly. You’ll get a clear explanation and price before any work.

✅ Diagnostic scan

✅ Battery/charging voltage test

✅ Fluid/leak/belt checks (if hydraulic)

✅ Clear pricing before work
