OBD-II Drive Cycle Recommendations

Most OBD-II monitors will complete more readily driving with a "steady throttle" during acceleration or cruise modes. Smooth throttle operation will minimize the time required for monitor completion. Fuel tank level should be 1/2 to 3/4, with 3/4 being the optimum desired level. The evaporative monitor may only operate during the first 30 minutes of engine operation. When executing the evaporative monitor, stay in part throttle and drive steadily to avoid fuel slosh.
