C0607 is set when the steering‑wheel‑angle sensor circuit reports a voltage that exceeds the normal operating range, indicating a high‑side fault. The fault is usually electrical in nature (short to voltage, open ground, or sensor failure) and often forces the stability and traction‑control systems into a fallback mode. In most cases the vehicle remains driveable but with reduced safety‑control functionality.
Internal short or open circuit in the sensor that forces the signal voltage high.
A short to a higher‑voltage source, an open ground, or corroded/broken wires in the sensor harness.
Loss of the sensor’s reference voltage due to a blown fuse or poor power supply.
Corroded or loose ground connection at the sensor causing an abnormal voltage reading.
Installation of a non‑OEM steering wheel or other devices that alter the sensor wiring or interference.
Internal fault in the control module that misinterprets the sensor data; this is the least common cause.
No. While a faulty control module can set this code, it is rarely the cause. The sensor or its wiring is the far more common source of the problem.
The vehicle will usually remain drivable, but stability and traction‑control systems may be disabled or limited. It is advisable to repair the issue promptly for safety.
Most vehicles require a calibration or relearn procedure after the sensor is replaced to ensure accurate angle readings.
Extremely low voltage can affect sensor operation, but a clean high‑voltage reading (circuit high) points more directly to a wiring or sensor fault rather than a simple voltage drop.
