Diagnostic Mode 05 - Read Oxygen Sensor Monitoring Test Results

Diagnostic Modes 01 - 09

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.

• Depending on scan tool and protocol used, the information displayed 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 be referenced by only a number.

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 Diagnostic Mode 06 - Read Test Results For Specific Diagnostic Functions ] for Oxygen Sensor Monitoring Test Results.

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's development process. e.g.:





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 requirements

• Exhaust system must be properly sealed between the catalytic converter and the cylinder heads.

• No DTCs stored in the DTC memory.

• Coolant temperature at least 80° C.

Work procedure

- Connect the scan tool.

- Start the engine and run at idle.

• If the engine does not start, crank the engine using starter for at least 5 seconds, do not switch the ignition off afterward under any circumstances.

- Select "Diagnostic Mode 05 - Check Lambda Test Results.".

- Select the desired "Test-ID" of the component or system that is to be monitored, e.g. "Test-ID 01: Oxygen Sensor Monitor Bank 1 - Sensor 1".

- Select the desired "Test-ID".

The current minimum and maximum values will be displayed on the scan tool screen.

The following table is a numerical list of all"Test-IDs" or " Hex-IDs" that may be selected.
