C0207 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 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.
