- Vehicle is in a closed-loop operation.
- Vehicle has been driven at greater than 1000 RPM for more than 35 seconds.
- Air flow parameter is less than 8 g/s.
- ECT is 158-257°F (70-125°C).
- IAT is -6 to 176°F (-21 to 125°C).
- Barometric pressure is greater than 21.3 in. Hg (72 kPa).
- Ignition voltage is greater than 9 volts.
- TWC calculated temperature is 1112-1247°F (600-675°C).

This DTC is sampled once at an idle when the above conditions are met. If the first test fails, the ECM will take more samples during the current ignition cycle or may take samples for up to 6 ignition cycles. The extra sampling is to ensure that a converter has failed, not just temporarily poisoned.
