why does my Toyota RAV4 Fifth Generation (2019-present) have a delayed steering response

Solution

1. Preparation

• Gather tools and parts: OBD-II scanner, socket set, power steering fluid, and safety gloves.
• Ensure the vehicle is parked on a level surface with the engine off and the keys removed from the ignition.

2. Check Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level against the dipstick.
• If low, add the recommended power steering fluid type (refer to the owner's manual for specifics).
• Inspect the fluid for contamination; if dirty, a fluid change may be necessary.

3. Inspect and Tighten Connections

• Visually inspect the wiring harness connected to the EPS unit for wear or disconnections.
• Use a socket set to tighten any loose bolts on the steering column or steering gear that may contribute to play or instability.

4. Testing Power Steering Pump

• Start the engine and turn the steering wheel from side to side to observe any changes in responsiveness.
• Use a pressure gauge to measure the output pressure of the power steering pump; it should fall within the manufacturer's specifications.

5. Replace Faulty Components

• If the EPS module is faulty, replace it by disconnecting the battery, removing the module, and installing a new one according to the manufacturer's instructions.
• Reconnect all electrical connections and ensure they are secure.

6. Final Assembly and Testing

• Reassemble any components that were removed during the repair.
• Start the vehicle and perform a test drive to ensure steering response is normal and there are no unusual noises.
