Column Reach Feedback Potentiometer Circuit Short to Battery
The steering column reach adjustment motor's position sensor is sending a constant high voltage signal to the ECU, like a stuck accelerator pedal. This means the sensor wire is touching the positive battery voltage instead of properly varying its signal.
The ECU monitors the potentiometer voltage output from the steering column reach motor feedback circuit. It expects a variable voltage signal between ground and battery voltage that correlates to the column's physical position. When a short to battery occurs, the voltage remains pinned high, preventing the ECU from detecting position changes.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Feedback Voltage | 0.5V to 4.5V (variable based on position) | Constant 12V or above 4.8V |
| Voltage Sweep Range | Full range variation during motor movement | No voltage variation; stuck high |
Code B2330 is a low-severity fault. Your vehicle is generally safe to drive to a workshop for diagnosis. However, do not ignore it indefinitely — low-severity codes often indicate developing problems that become expensive if neglected. Book a diagnostic appointment within 2–4 weeks. If you notice any additional symptoms (rough running, power loss, unusual smells), treat it as higher priority.
Once the fault is repaired, B2330 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
