P0823 — Gear Lever X Position Circuit Intermittent

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0823

P0823 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0823 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0823 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0823 fault code is set when the control module detects intermittent readings in the gear lever X position circuit. This typically indicates an issue in the circuit's ability to consistently transmit the gear lever's position to the control module. The inconsistency can be due to electrical interruptions or poor connections within the circuit. The gear lever X position is a critical input for the transmission control module, as it uses this data to determine the selected gear.
