C0207 Buick Code - Steering Wheel Position Sensor

Quick Answer

The steering wheel position sensor produces 2 separate voltage signals to indicate steering wheel position to the Real Time Damping (RTD) module. Common causes include Faulty Steering Wheel Position Sensor, Steering Wheel Position Sensor harness is open or shorted, Steering Wheel Position Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C0207 Buick Description

The steering wheel position sensor produces 2 separate voltage signals to indicate steering wheel position to the Real Time Damping (RTD) module. The RTD module converts each signal into a Pulse Width Modulated (PWM) signal to indicate steering wheel position to the Electronic Brake Control Module (EBCM). The EBCM supplies 5 volts to the RTD module on each steering wheel position PWM serial data circuit. The RTD module toggles each of these voltages to ground in order to create the PWM signals. Each PWM signal must have a frequency of 121-134 Hz and a duty cycle of 9-91 percent in order to be a valid steering wheel position signal. With each 360 degree rotation of the steering wheel, each signal transitions from the minimum duty cycle to the maximum duty cycle and then back to the minimum duty cycle. The steering wheel position signals are spaced 90 degrees apart. Therefore, the duty cycles of the 2 signals usually differ, depending on steering wheel position.

Frequently Asked Questions about C0207 Buick Code

1. What does the OBDII code C0207 mean on a Buick?

C0207 indicates a problem with the Steering Wheel Position Sensor, which monitors the angle and rotation of the steering wheel for stability control systems.

2. What are common symptoms of the C0207 code in a Buick?

Symptoms may include the stability control or traction control warning lights turning on, erratic steering behavior, or issues with electronic stability system performance.

3. What causes the C0207 code to appear on a Buick?

Common causes include a faulty steering wheel position sensor, damaged wiring or connectors, or issues with the stability control system module.

4. Can I drive my Buick with a C0207 code?

While you can drive with this code, it is not recommended, as it may disable important safety features like traction and stability control.

5. How is the C0207 code diagnosed in a Buick?

A technician will use a scan tool to confirm the code, inspect the steering wheel position sensor and its wiring, and perform tests to determine if the sensor is functioning properly.

6. How do you fix the C0207 code on a Buick?

Repairs may include replacing the steering wheel position sensor, repairing damaged wiring, or reprogramming the stability control module if necessary.

7. What tools are needed to repair the C0207 code on a Buick?

You may need an OBDII scan tool, a multimeter for testing wiring, and potentially specialized tools to remove and replace the steering wheel position sensor.

8. How much does it cost to fix the C0207 code on a Buick?

The repair cost can vary, but replacing the steering wheel position sensor typically ranges between $200 and $400, including parts and labor.

9. Can a dead battery cause the C0207 code on a Buick?

A dead or weak battery can sometimes cause electrical issues, but it is less likely to directly trigger a C0207 code unless it affects the stability control system.

10. Does the C0207 code reset itself after repairs on a Buick?

In most cases, the code will need to be cleared using an OBDII scan tool after the issue is resolved.
