Diagnostic Mode 05 - Read Oxygen Sensor Monitoring Test Results

Diagnostic Modes 01 - 09

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.

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.
