Diagnostic Mode 05 - Read Oxygen Sensor Monitoring Test Results: Notes
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 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.:
| Minimum Value | |
|---|---|
| GST Manual 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 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.

If the engine does not start, crank the engine using starter for at least 5 Sec, do not switch the ignition off afterward under any circumstances.
-- Select "Mode 5: 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.
| Test-ID (Hex-ID) | Component or System |
|---|---|
| Test-ID 01 ($01) Test-ID 01 ($01): Oxygen Sensor Monitor Bank 1 - Sensor 1 | Oxygen Sensor Monitor Bank 1 - Sensor 1 |
| Test-ID 02 ($02) Test-ID 02 ($02): Oxygen Sensor Monitor Bank 1- Sensor 2 | Oxygen Sensor Monitor Bank 1- Sensor 2 |
