Column Tilt Feedback Potentiometer Circuit Failure
The steering column tilt motor has a position sensor (potentiometer) that tells the computer where the column is adjusted; when this sensor fails or its circuit breaks, the ECU can't confirm the column's location. Think of it like a dimmer switch that's broken—the light won't respond properly because feedback is lost.
The ECU monitors analog voltage from the tilt potentiometer as the column moves up and down, expecting a smooth voltage sweep from approximately 0.5V to 4.5V as the mechanism reaches its limits. If voltage is out of range, stays constant, or is missing entirely, the ECU detects a circuit failure and sets the fault code.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Potentiometer Output Voltage | 0.5V to 4.5V (proportional to column position) | Below 0.2V, above 4.8V, or stuck at one value |
| Circuit Resistance | Variable (100–10kΩ range typical) | Open circuit (infinite) or short to ground |
Code B2332 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, B2332 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.
