Where is the OBD interface located on the Cavalier?

[LaCourtney]

The OBD interface of the Cavalier is located inside the interior trim panel below the steering wheel, near the driver's knee area. Here is more information about the OBD system: 1. The OBD system continuously monitors the engine's operating condition to check if the vehicle's exhaust emissions exceed the standard. If they do, it will immediately issue a warning. When a system malfunction occurs, the malfunction indicator light or check engine warning light will illuminate, and the powertrain control module will store the fault information in memory. The fault codes can be read from the PCM through a specific procedure. Based on the fault code prompts, maintenance personnel can quickly and accurately determine the nature and location of the fault. 2. The OBD system monitors the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, fuel system, EGR system, and other components in real-time. By connecting to the ECU through various emission-related component information, when an emission fault occurs, the ECU records the fault information and related codes and alerts the driver by illuminating the malfunction indicator light.
