About P0723

P0723 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 P0723 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

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 P0723 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 P0723 fault code is triggered when the Transmission Control Module (TCM) detects intermittent signals from the output speed sensor circuit. The output speed sensor measures the rotational speed of the transmission's output shaft, which is crucial for the TCM to manage gear shifting and ensure optimal transmission performance. An intermittent fault in this sensor circuit indicates sporadic disruptions in signal transmission, which can arise from loose or poor connections, wiring issues, or intermittent sensor failures. These intermittent signals can lead to erratic vehicle behaviour, such a...
