C0607 Steering Wheel Angle Sensor Circuit High

Check engine lightUsually off
EmissionsNot relevant

Limp modePossible

C0607 is the mirror image of C0606: the steering angle signal sits above its allowed ceiling. Usual reasons are a signal wire shorted to the sensor supply or to battery voltage, an open ground at the sensor, after which the line drifts up, or an internal fault driving the output to its top end. In the Kelsey-Hayes quadrature sensor a valid high state is near 4.4 V and readings beyond the upper limit are faults; in the Bosch PWM concept a line stuck at battery level yields no valid duty cycle, and the patent names a short to battery as detectable. HELLA points out that a redundant double angle sensor lets such single-channel failures be caught. No maker publishes C0607. The ESC lamp lights and stability control stays off until the fault is gone.

Likely causes

Signal wire shorted to the sensor supply or battery voltage
Open sensor ground, signal floats high
Sensor output stage failed high

Symptoms

  • ESC and traction control warning lamps on
  • Steering angle shown at an implausible maximum value
  • Lane keeping or park assist switched off
