OBD II Drive Cycle Procedures

2. Evaporative emission control system leak monitor (P0442, P0450, P0455)

Test conditions and procedures
1. Perform a road test in a state where all of the following conditions are satisfied.
1. Engine coolant temperature: 45° C (113° F) or less (before starting drive test, engine stopped)
2. Atmospheric temperature: 5° C (41° F) or more, 45° C (113° F) or less
3. A/T conditions:
- Selector lever position: D range
- Overdrive switch: ON
2. One trip monitoring is completed by making a trip in the following pattern (from when the engine is started to when the ignition switch is placed in the OFF position). (Required time approx. 8 minutes)
*1: Check that both engine coolant temperature and air intake temperature satisfy requirement 1 (It takes approx. 8 minutes.)
*2: Monitor preparation period; Start the engine, and accelerate to 89 - 97 kph (55 - 60 mph). For this period, acceleration, deceleration, or braking may be carried out.
Continue driving between 89 and 97 kph (55 and 60 mph) for 200 seconds or more. For this period, braking or throttle operation may be carried out if vehicle speed is within the specified value.
*3: Drive between 89 and 97 kph (55 and 60 mph) at a constant throttle angle (by not moving the throttle pedal as much as possible) for 150 seconds or more during monitor. Moreover, do not turn the steering wheel suddenly.
*4: Decelerate and stop the vehicle. After stop, turn off the ignition switch.
