(a) Preconditions

The monitor will not run unless:

- 2 minutes or more have elapsed since the engine was started.

- The Engine Coolant Temperature (ECT) is 75°C (167°F) or more.

- Cumulative driving time at a vehicle speed of 30 mph (48 km/h) or more exceeds 6 minutes.

- Air-fuel ratio feedback control is performed.

(b) Drive Pattern for front A/F sensor and HO2 sensor

(1) Connect the intelligent tester to the DLC3.
