C0207 Saturn 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 Saturn 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 Saturn Code

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

The C0207 code indicates a fault with the Steering Wheel Position Sensor, which monitors the position and rotation of the steering wheel to assist with systems like stability control.

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

Common symptoms include the ABS or traction control warning light illuminating, reduced stability control performance, or inaccurate steering feedback.

3. What causes the C0207 code to trigger?

This code can be caused by a faulty steering wheel position sensor, damaged wiring or connectors, or an issue with the electronic control module (ECM) or associated systems.

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

While the vehicle may still be drivable, safety systems like the ABS and traction control may not function properly, so itâ€™s advisable to address the issue promptly.

5. How do you diagnose the C0207 code on a Saturn?

Diagnosing involves scanning the vehicle with an OBDII tool, inspecting the steering wheel position sensor, checking for damaged wiring or connectors, and verifying related system functionality.

6. How do you fix the C0207 code in a Saturn?

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

7. How much does it cost to fix the C0207 code on a Saturn?

The repair cost varies but typically ranges between $150 and $400, depending on whether the sensor, wiring, or control module needs replacement.

8. Can a C0207 code be caused by low battery voltage?

Yes, low battery voltage or electrical issues can sometimes cause this code, as the sensor relies on consistent power for accurate readings.

9. Does the C0207 code affect other vehicle systems?

Yes, it can impact the performance of ABS, traction control, and electronic stability control systems since those rely on accurate steering position data.

10. How can I prevent the C0207 code from recurring?

Regularly inspect the sensor and related wiring for damage, keep the ECM updated, and ensure proper vehicle maintenance to prevent electrical or mechanical issues.
