- Procedure
- Evaluation of output of oxygen sensor signals:
- Evaluation test-ID 01 Bank 1 Sensor 2: rich to lean sensor barrier voltage
- Evaluation test-ID 02 Bank 1 Sensor 2: lean to rich sensor barrier voltage
- Evaluation test-ID 07 Bank 1 Sensor 2: Minimum voltage at sensor for test cycle
- Evaluation test-ID 08 Bank 1 Sensor 2: Maximum voltage at sensor for test cycle
- Evaluation test-ID 129 Bank 1 Sensor 1: Actual value of oxygen sensor voltage
- Evaluation test-ID 130 Bank 1 Sensor 1: Control barrier voltage
- Evaluation test-ID 131 Bank 1 Sensor 1: Dynamic value
- Evaluation test-ID 132 Bank 1 Sensor 1: Oxygen sensor shift via oxygen sensor control behind Three Way Catalytic Converter (TWC) (bank 1 sensor 2)
- Diagnostic mode 6: Check test results of components that are not continuously monitored
