Why Your Steering Feels Weak on Turns (Causes & Fixes)

Weak or unresponsive steering when turning often indicates issues with the power steering system, suspension components, or tire conditions that reduce steering assist or feedback.

Potential Causes

Low power steering fluid (hydraulic) High Probability

Insufficient fluid reduces hydraulic assist, making steering feel weak or heavy at turns

Electric Power Steering assist system fault Medium Probability

EPS motor or control unit malfunction reduces assist torque, leading to weak steering feel

Tire pressure imbalance or incorrect pressure Medium Probability

Underinflated or uneven tires increase resistance and reduce steering responsiveness

Worn suspension/steering linkage Medium Probability

Worn ball joints, tie rods, or bushings cause loose steering feel and poor response

Diagnostic Steps

  1. Check Tire Pressure and Condition

    Measure tire pressures and adjust to manufacturer specifications; inspect tires for uneven wear

  2. Inspect Power Steering Fluid or EPS Status

    For hydraulic systems, check fluid level and condition; For EPS, scan for EPS-related codes

  3. Scan for DTCs and Live Data

    Connect OBD scanner to read EPS and steering angle sensor data

  4. Inspect Steering Linkage

    Raise vehicle and check tie rods, ball joints, and bushings for play

OBD-II Live Data Analysis

Use a scan tool to monitor these parameters. Comparing live values against the normal range can help identify the root cause.

PID

Steering Angle Sensor

Normal Range Consistent with wheel position
Abnormal Condition Erratic or offset values without turning
Technical Insight: Indicates sensor or alignment issue affecting steering feedback
PID

EPS Torque Assist

Normal Range Within manufacturer spec
Abnormal Condition Low assist torque at low speeds
Technical Insight: Suggests EPS assist motor or control problem affecting steering assist

Frequently Asked Questions

Why does my steering feel weak when turning?

Weak steering during turns can be caused by low power steering fluid, a fault in the electric power steering assist system, or an imbalance in tire pressure. It's important to diagnose the issue to ensure safe driving.

How can I check if my power steering fluid is low?

To check your power steering fluid, locate the reservoir under the hood, remove the cap, and check the fluid level against the markings on the side. If it's below the recommended level, top it up with the appropriate fluid.

What should I do if my electric power steering is not working properly?

If your electric power steering (EPS) is malfunctioning, you should connect an OBD scanner to check for EPS-related codes and inspect the steering angle sensor data. If issues persist, consider consulting a professional mechanic.

How do I fix weak steering caused by low tire pressure?

To fix weak steering due to low tire pressure, measure the tire pressures using a gauge and adjust them to the manufacturer's specifications. Also, inspect the tires for uneven wear, which may indicate other issues.

Can I fix weak steering myself?

Yes, you can address weak steering by adjusting tire pressure and topping up power steering fluid if it's low. However, if the problem persists, it's advisable to seek professional help to diagnose and fix underlying issues.
