Diagnostic Mode 05 - Read Oxygen Sensor Monitoring Test Results

Diagnostic Mode 05 - Read Oxygen Sensor Monitoring Test Results

NOTE: 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. Diagnostic Mode 06 - Read Test Results For Specific Diagnostic Functions

The individual tests in Diagnostic Mode 05 display the results of emission related components and systems which are not continuously monitored.

The min max values for each individual test in Mode 05 represent the min max operating values for a properly operating system. This data is provided to the individual aftermarket scan tool companies for development of their scan tool. Depending on the scan tool being used, the min max values shown may vary, or be rounded up or down to the nearest decimal point depending on the aftermarket scan tool company development process. e.g.:

Minimum Value
GST documentation 0.3499
Aftermarket Scan Tool display 0.35

Depending on the scan tool and protocol used, the information displayed in Diagnostic Mode 06 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and may be referenced by only a number.

Test-ID (Hex-ID) Component or System
