B2330: Telescopic Position Sensor Short
Diagnostic trouble code B2330 is triggered when the steering column control module (or associated memory module) detects an abnormally high voltage on the telescopic adjustment feedback potentiometer circuit, consistent with a short to power or battery voltage. This variable resistance sensor reports the column's longitudinal position to the module, enabling memory settings and easy entry/exit functions. When the signal is stuck at its maximum value due to the short, the system cannot determine the actual column position, disabling automatic movements and storing the DTC.
1. Commonly Affected Makes
2. Most Common Causes
- Short circuit in the reach potentiometer wiring to the reference voltage or battery power circuit.
- Faulty or worn internal telescopic adjustment feedback potentiometer in the steering column.
- Corroded, bent, or shorted connectors at the column position sensor.
- Internal failure in the steering column control module (SCCM) or associated memory module.
- Mechanical damage to the steering column harness from repetitive telescopic adjustment movement.
3. Symptoms You Will Notice
- Automatic telescopic adjustment inoperative or disabled.
- Memory position recall for steering column does not function.
- Easy entry/exit feature (column retract/extend) not working.
- Steering column may be stuck in one position.
- Check engine or service column light may illuminate.
4. Step-by-Step Diagnosis
Scan for DTCs and verify B2330 is present.
Inspect wiring and connectors between the telescopic position sensor and SCCM for shorts to power or battery voltage.
Test the feedback potentiometer resistance and voltage output per manufacturer specifications.
Check for mechanical binding or damage in the telescopic mechanism.
If wiring and sensor are OK, suspect a faulty SCCM or memory module.
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is generally safe to drive with code B2330. The steering column will remain in its current position, but automatic adjustments and memory functions will be disabled. Have it diagnosed soon to restore full functionality.
How much does it cost to fix?▼
Repair costs typically range from $150 to $600, depending on the cause. A faulty potentiometer or wiring repair may be on the lower end, while replacing the steering column control module can be more expensive.
