B2330 – OBD-II DTC

OBD-II DTC B2330 – Column Reach Feedback Potentiometer Circuit Short to Battery

DTC B2330 meaning

DTC B2330 refers to a diagnostic trouble code indicating a problem with the column reach feedback potentiometer circuit. This circuit is responsible for providing feedback to the vehicle’s control module regarding the position of the steering column. A short to battery condition suggests that there is an electrical fault, causing the circuit to receive an unintended voltage directly from the battery, which can lead to incorrect readings and potential malfunctions in steering column adjustments.
