5.10 O2 Monitor Tests
OBD II regulations require applicable vehicles monitor and test oxygen (O2) sensors to determine problems related to fuel and emissions. The O2 Monitor Tests allows retrieval of completed O2 sensors monitor test results.
• The O2 Monitor Tests is not an on-demand test. O2 sensors are not tested when selected via the menu.
O2 sensors are tested when engine operating conditions are within specified limits.
• If the vehicle communicates using a controller area network (CAN), O2 Monitor Tests are not supported by vehicle. A message is displayed. Refer to “5.11
Diagnostic Monitor Tests” on page 38 for O2 monitor data.
• O2 sensors are located before (upstream) and after
(downstream) catalyst(s). Sensors are named (xy) for their position to both cylinder banks and catalysts.
– The O2 sensor for cylinder bank 1 has prefix 1y while O2 sensor for cylinder bank 2 has prefix
2y.
– The O2 sensor upstream of catalyst (closest to engine) has suffix x1 while O2 sensor downstream of catalyst has suffix x2. If vehicle contains more catalysts, O2 sensor downstream of second catalyst has suffix x3 and O2 sensor downstream of next catalyst has suffix x4.
– For example, O2S21 is upstream O2 sensor for cylinder bank 2.
The following O2 Sensor Tests are available:
• Rich-to-lean sensor threshold voltage
• Lean-to-rich sensor threshold voltage
• Low sensor voltage for switch time
• High sensor voltage for switch time
• Rich-to-lean sensor switch time
• Lean-to-rich sensor switch time
• Minimum sensor voltage test cycle
• Maximum sensor voltage test cycle
• Time between sensor transitions
• Sensor period
• Manufacturer specific tests
From Special Tests Menu:
1. Select O2 Monitor Tests.
• Use the UP and DOWN keys until O2
Monitor Tests is highlighted.
