Solution

1. Preparation

Gather tools and parts before starting the repair.
Tools required: OBD-II scanner, multimeter, socket set, torque wrench, steering wheel puller.
Safety warning: Disconnect the battery before working on electrical systems.

2. Remove Steering Wheel

a. Disconnect the battery and wait for at least 10 minutes to allow the airbag system to discharge.
b. Remove the steering wheel retaining nut using a socket.
c. Use a steering wheel puller to safely detach the steering wheel from the steering column.

3. Remove Steering Angle Sensor

a. Locate the steering angle sensor on the steering column.
b. Disconnect the wiring harness from the sensor.
c. Remove the mounting screws securing the sensor using a socket set.
d. Carefully pull the sensor free from the steering column.

4. Install New Steering Angle Sensor

a. Position the new sensor onto the steering column.
b. Secure it with the mounting screws and tighten them to the manufacturer’s specified torque (usually around 89 in-lbs).
c. Reconnect the wiring harness to the new sensor.

5. Reassemble Steering Wheel

a. Align the steering wheel correctly and press it back onto the steering column.
b. Replace the steering wheel retaining nut and tighten it to the specified torque (approximately 35 ft-lbs).
c. Reconnect the battery.

6. Recalibrate Steering Angle Sensor

a. Use an OBD-II scanner to access the steering angle sensor calibration function.
b. Follow the prompts to calibrate the sensor according to the manufacturer's instructions.
