what does it mean when the EPS light comes on in my Toyota Camry XV70 (2018-2024)?

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.
• Safety Warnings: Ensure the vehicle is on a flat surface and the ignition is off before beginning work.

2. Address Error Codes

• Use the OBD-II scanner to read and document any error codes.
• Clear the codes and test drive the vehicle to see if the EPS light returns.

3. Check Power Steering Fluid

• Locate the power steering fluid reservoir.
• If the level is low, top it off with the recommended fluid type (refer to owner's manual).
• Inspect for leaks in hoses or connections.

4. Inspect Wiring and Connections

• Visually inspect the wiring harness connected to the EPS motor for fraying or disconnections.
• Check the connectors for corrosion; clean and reconnect if necessary.

5. Test EPS Motor

• Disconnect the EPS motor and measure the voltage and current with a multimeter while turning the steering wheel.
• If the readings are outside the manufacturer specifications, replace the EPS motor.

6. Check Steering Angle Sensor

• Use the OBD-II scanner to verify the steering angle sensor's calibration.
• If out of specification, recalibrate the sensor using the scanner or replace it if faulty.
