Diagnostic Mode 05 - Read Oxygen Sensor Monitoring Test Results






Diagnostic Modes

The information provided in Modes 01 through 09 displays the various levels of emission related data that may be monitored, as well as the ability to retrieve and read stored DTC trouble codes , erase stored DTC trouble codes, generate readiness codes, and select the various PIDs and Test-IDs used within the modes to monitor the engine, and emission related component parameters.

The following table provides a link to all diagnostic modes that monitor all components and systems which influence the emission quality.

Depending on scan tool and protocol used, the information in diagnostic mode 01 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), or On-Board Diagnostic Monitor Identifier (OBDMID).

Diagnostic Mode 05 - Read Oxygen Sensor Monitoring Test Results

Mode 05 may not be supported on all systems. On systems where Diagnostic Mode 05 is not supported, refer to Diagnostic Mode 6 for Oxygen Sensor Monitoring Test Results.

Mode 05 allows access to the Oxygen Sensor test results. Mode 05 is divided into test identifiers (TIDS).

Depending on scan tool and protocol used, diagnostic mode 05 and the information provided may be referred to by a different name.
