Code Definition

P062C — ECM vehicle speed control performance error.

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

About P062C

P062C 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 P062C is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour.

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 P062C 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 fault code P062C is set when the Engine Control Module (ECM) identifies a performance issue with the vehicle speed control system. This diagnostic trouble code indicates that the ECM's ability to monitor or control the vehicle's speed is not functioning as expected. The problem could be due to issues in the ECM's processing capabilities, faults in the vehicle speed sensors, or discrepancies in the speed control system that the ECM is unable to correctly interpret or manage.
