OBD II Drive Cycle Procedures

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

Test conditions/procedure
1. All of the following conditions should be satisfied when the drive test is carried out.
1. Engine coolant temperature: 45°C (113°F) or lower (before carrying out testing while engine is stopped)
2. Outside air temperature: 5°C (41°F) or higher, 45°C (113°F) or lower
3. A/T condition:
- Selector lever position: D range
- Overdrive switch: ON
- Power/economy changeover switch: Power
2. Carry out one trip monitoring according to the following drive pattern (from starting of the engine until ignition is turned off). (Takes approximately 8 minutes.)
*1: Check that both the engine coolant temperature and intake air temperature satisfy the conditions in 1. above (when engine is stopped).
*2: Monitor pre-preparation period: start the engine and accelerate to a speed of between 89 - 97 kph (55 - 60 mph). Acceleration, deceleration and braking can be carried out during this period. Drive for 60 seconds or more while maintaining the vehicle speed at between 89 - 97 kph (55 - 60 mph). Braking and throttle operations can be carried out during this time as long as the vehicle speed remains within the specified range.
<>3: Monitoring period: drive for 150 seconds or more while maintaining the throttle opening angle at a constant angle (keeping throttle variations as small as absolutely possible) and the vehicle speed at between 89-97 kph (55 - 60 mph). Drive as consistently as possible during this time, without making any sudden steering wheel movements.
<>4: Decelerate to a stop. After the vehicle has stopped, turn the ignition switch to OFF.
